Need help coding MorseCode in JavaCreate Class MorseCodeClient. T.pdffastechsrv
Need help coding MorseCode in Java:
Create Class MorseCodeClient. This represents a Client that allows a user communicate with a
server across a network. The server saves the message and then relays the message to another
client This is a JFrame application and should extend JFrame and Implement Runnable. The
client application should allow the user to type English-language phrases in a JTextArea. When
the user sends the message, the client application encodes the text into Morse code and sends the
coded message through the server to the other client. Create class MorseCodeClientTest, this is a
test class for morse code client and uses the main method to created new instance of
MorseCodeClient.

Leveraging Scala Macros for Better ValidationTomer Gabel
A talk given at Scalapeño 2014 and JavaOne 2014 (video links to follow).
Data validation is a common enough problem that numerous attempts have been made to solve it elegantly. The de-facto solution in Java (JSR 303) has a number of shortcomings and fails to leverage the powerful Scala type system. The release of Scala 2.10.x introduced a couple of experimental metaprogramming features, namely reflection and macros. In this talk I'll introduce macros by way of a practical example: implementing a full-blown data validation engine, utilizing def macros and a Scala DSL to enable elegant validator definition syntax and call-site.
Below is the assignment description and the file I have written..pdfinfo673628
Below is the assignment description and the file I have written. I would love to test this file to
make sure that everything is satisfied (vector with all modes in ascending order). I\'m having a
really hard time constructing a main method to test it. Help!!
-------------------------------------------------------
The mode is the value that appears most often in a set of data. Write a function named findMode
that takes as parameters an array of int and the size of the array, and returns a vector containing
the mode(s). If there is just a single most frequent value, the vector will only contain that one
value, but if multiple values tie for maximum frequency, the vector will need to contain all such
values. This includes the case where every number in the array appears only once. Each mode
should appear only once in the vector. The values in the vector that is returned must be in
ascending order. If you need to sort a vector, it\'s similar to sorting an array, but specifying the
beginning and end of the vector look a little bit different. If your vector is named result, then it
would look like this: \"std::sort(result.begin(), result.end());\".
-------------------------------------------------------
#include // needed for the sort() function
#include // needed to use the vector type
#include // needed for the main function
using std::vector;
using std::sort;
vector findMode(int array[], int size)
{
int maxFreq = 1; // initalizing the largest frequency to be 1
vector result; // results is an empty vector
//Initializing the loop through the integer array
for (int i = 0; i < size; i++)
{
int count = 1; //started the counter at 1
//started the the loop after the 1st entry, looking for matches with the value at index i.
for (int j = i + 1; j < size; j++)
{
//if an entry matches another, then add one to the counter
if (array[i] == array[j])
{
count++;
}
}
//when the counter is equal to the max frequency, the integer is added to the result vector.
if (count == maxFreq)
{
result.push_back(array[i]);
}
//when the counter for i is greater than the max frequency, updates the maxFreq, clear the values
stored in the result vector, and push the value to the empty vector.
if (count > maxFreq)
{
maxFreq = count;
result.clear();
result.push_back(array[i]);
}
}
//sort the modes in ascending order
sort(result.begin(), result.end());
return result;

“The Meaning of July Fourth for the Negro” by Frederick Douglas
1. What is the event or rhetorical moment I will be analyzing and why. Give a brief summary.
· I will be analyzing a speech by Fredrick Douglas that he gave on July 5th in 1852 called, “The Meaning of July Fourth for the Negro”. I chose this speech because I first read this speech this past spring semester in my gender studies class and it was so well written and worded that it literally just brought me to tears with so much emotion behind it. I want to analyze how Douglas put this together and his rhetorical process that he used in order to touch so many people with his words.
2. What methods of evaluation will I be looking for?
· The methods of evaluation I will be looking for in this speech are the following:
(I) The speech objective
(II) The audience and context of the speech
(III) The speeches context and structure
(IV) The delivery skills and techniques he used
(V) Intangibles

Deforestation
The Amazon forest alone creates 20% of the worlds oxygen. It has decreased by 17% in the past 50 years because of deforestation (conserve-energy-future.com). Forest’s in general only cover 30% of the world (conserve-energy-future.com ). Deforestation is killing the trees that produce oxygen, without it humans can’t survive. Deforestation should be prohibited because large plants such as trees recycle air.
If deforestation is such a problem, why does it happen? Deforestation extracts the forest of its resources. It turns the forests into farms, ranches, or urban areas. The wood from trees are used for building or could be sold as fuel. Another big cause of deforestation is quarry’s. Quarry’s take up a lot of land, and once the quarry is abandoned is almost impossible to fix. Hydropower requires dams to be built. Dams create an enormous amount of flooding, which kills thousands of trees. The increase of population is also a cause of deforestation. The more people that are on earth the more land and resources we demand.
If deforestation continues it will have a huge negative impact on our air supply. Everyday a piece of the forests is being destroyed. The more trees that are being destroyed the less oxygen can be produced. Trees use photosynthesis to covert carbon dioxide into oxygen. Photosynthesis is the main producer of oxygen, and respiration and decay remove it. Urban areas have less oxygen then rural areas, because they don’t have many plants. Throughout history oxygen levels have been steadily decreasing. Once the oxygen levels hit 7% the air is too low to support human life (thenaturalhealthplace.com). Finding ways to apply reforestation would help increase oxygen.
There are many ways to apply reforestation to reverse the harm that’s been don’t to the world. One way is to plant trees. There are some cities who have made vertical forests. They plant trees and plants that surround the building. Going paperless would help as well. Since technology has advanced, paper isn’t really needed as often. Recycling and buying recycled products will help as well. The more that people recycle there will be less demand for natural resources and trees. Reforestation will help to reduce the concentration of carbon dioxide in the air.
Deforestation does have a huge negative impact on our world, but there are quite of bit of positive too. The positive effects of deforestation are that it does gives humans space to grow. With growth comes civilizations which means more jobs and revenue. Deforestations also gives us more food and resources to satisfy our needs. It means a more comfortable life for humans. The consequences of deforestation is not worth the temporary comfort that humans get from it.
Deforestation is a serious problem to maintain life on this planet. The decrease in oxygen could eventually mean the end to human kind. If we don’t do anything abo.

· I will be analyzing a speech by Fredrick Douglas that he gave on July 5th in 1852 called, “The Meaning of July Fourth for the Negro”. I chose this speech because I first read this speech this past spring semester in my gender studies class and it was so well written and worded that it literally just brought me to tears with so much emotion behind it. I want to analyze how Douglas put this together and his rhetorical process that he used in order to touch so many people with his words.
2. What methods of evaluation will I be looking for?
· The methods of evaluation I will be looking for in this speech are the following:
(I) The speech objective
(II) The audience and context of the speech
(III) The speeches context and structure
(IV) The delivery skills and techniques he used
(V) Intangibles

Deforestation
The Amazon forest alone creates 20% of the worlds oxygen. It has decreased by 17% in the past 50 years because of deforestation (conserve-energy-future.com). Forest’s in general only cover 30% of the world (conserve-energy-future.com ). Deforestation is killing the trees that produce oxygen, without it humans can’t survive. Deforestation should be prohibited because large plants such as trees recycle air.
If deforestation is such a problem, why does it happen? Deforestation extracts the forest of its resources. It turns the forests into farms, ranches, or urban areas. The wood from trees are used for building or could be sold as fuel. Another big cause of deforestation is quarry’s. Quarry’s take up a lot of land, and once the quarry is abandoned is almost impossible to fix. Hydropower requires dams to be built. Dams create an enormous amount of flooding, which kills thousands of trees. The increase of population is also a cause of deforestation. The more people that are on earth the more land and resources we demand.
If deforestation continues it will have a huge negative impact on our air supply. Everyday a piece of the forests is being destroyed. The more trees that are being destroyed the less oxygen can be produced. Trees use photosynthesis to covert carbon dioxide into oxygen. Photosynthesis is the main producer of oxygen, and respiration and decay remove it. Urban areas have less oxygen then rural areas, because they don’t have many plants. Throughout history oxygen levels have been steadily decreasing. Once the oxygen levels hit 7% the air is too low to support human life (thenaturalhealthplace.com). Finding ways to apply reforestation would help increase oxygen.
There are many ways to apply reforestation to reverse the harm that’s been don’t to the world. One way is to plant trees. There are some cities who have made vertical forests. They plant trees and plants that surround the building. Going paperless would help as well. Since technology has advanced, paper isn’t really needed as often. Recycling and buying recycled products will help as well. The more that people recycle there will be less demand for natural resources and trees. Reforestation will help to reduce the concentration of carbon dioxide in the air.
Deforestation does have a huge negative impact on our world, but there are quite of bit of positive too. The positive effects of deforestation are that it does gives humans space to grow. With growth comes civilizations which means more jobs and revenue. Deforestations also gives us more food and resources to satisfy our needs. It means a more comfortable life for humans. The consequences of deforestation is not worth the temporary comfort that humans get from it.
Deforestation is a serious problem to maintain life on this planet. The decrease in oxygen could eventually mean the end to human kind. If we don’t do anything abo.

Question 1 [14 marks]
Financial statement disclosures
You are the financial accountant for Superstore Ltd, and are in the process of preparing its financial statements for the year ended 30 June 2018. Whilst preparing the financial statements, you become aware of the following situations:
1. On 1 July 2017, the directors made a decision, using information obtained over the last couple of years, to revise the useful life of an item of manufacturing equipment. The equipment was acquired on 1 July 2015 for $800,000, and has been depreciated on a straight-line basis, based on an estimated useful life of 10 years and residual value of nil. Superstore Ltd uses the cost model for manufacturing equipment. The directors estimate that as at 1 July 2017, the equipment has a remaining useful life of 6 years and a residual value of nil. No depreciation has been recorded as yet for the year ended 30 June 2018 as the directors were unsure how to account for the change in the 2018 financial statements, and unsure whether the 2016 and 2017 financial statements will need to be revised as a result of the change.
2. In June 2018, the accounts payable officer discovered that an invoice for repairs to equipment, with an amount due of $20,000, incurred in June 2017, had not been paid or provided for in the 2017 financial statements. The invoice was paid on 12 July 2018. The repairs are deductible for tax purposes. The accountant responsible for preparing the company’s income tax returns will amend the 2017 tax return, and the company will receive a tax refund of $6,000 as a result (30% x $20,000). No journal entries have been done as yet in the accounting records of Superstore Ltd, as the directors are unsure how to account for this situation, and what period adjustments need to be made in.
3. Superstore Ltd holds shares in a listed public company, ABC Ltd, which are valued in the draft financial statements on 30 June 2018 at their market value on that date - $600,000. A major fall in the stock market occurred on 10 July 2018, and the value of Superstore’s shares in ABC Ltd declined to $250,000.
4. On 21 July 2018, you discovered a cheque dated 20 April 2018 of $32,000 authorised by the company’s previous accountant, Max. The payment was for the purchase of a swimming pool at Max’s house. The payment had been recorded in the accounting system as an advertising expense. You advise the directors of this fraudulent activity, and they will investigate.
Assume that each event is material.
Required:
i) State the appropriate accounting treatment for each situation. Provide explanations and references to relevant paragraphs in the accounting standards to support your answers. Where adjustments to Superstore Ltd’s financial statements are required, explain which financial statements need to be adjusted (ie. 2016, 2017, 2018 or 2019).
ii) Prepare any note disclosures and adjusting j.

Anna in the Tropics
Literature has the power to affect even the humblest of lives. Anna in the Tropics
presents the story of a family of Cuban cigar rollers whose lives in the 1920s Florida are
brightened up and disturbed at the same time by a stranger, a lector, who reads aloud about
the passions of Tolstoy and his heroine Anna Karenina. It is common practice for employees
at the factory run by this Cuban family to be entertained by as they carry out the mundane
chores at hand – those of rolling of cigars and sorting tobacco leaves. But as those in the
factory begin to get caught up in Tolstoy’s classic, willingly or not, the book begins to work
subtle and profound changes in their emotional lives. This essay will analyze the themes
covered in Anna in the Tropics, even as it seeks to explore the various ways in which the
play’s characters are affected as the lector reads to them – along with their fellow workers, to
educate and stimulate their minds in the course of the doldrums of their repetitive tasks.
One of the very first things to note in this story is how certain tensions between old
traditions and new ways are reflected. The factory workers, for instance, are threatened by
new, mechanical cigar rolling machines because they themselves roll cigars by hand, which is
the traditional way (Cruz 19). It is not just the workers whose future is uncertain, however.
Even the very tradition of the lector, who reads out loud to the cigar rollers so that any tedium
in the factory may be broken, while at the same time facilitating the ease of passing time, is at
risk (Cruz 8). Since listening to the lector is often the closest thing to a formal education that
cigar-rollers might experience, the ending of this tradition, in particular, could signify the
demise of an informal method of learning (Aiello).
The significance of the lector is not only about giving factory workers some
semblance of an informal education, however, but it is also reflective of the theme of Cuban
heritage that is present throughout the play. The Cuban culture and traditions comprise a key
theme because first, the play is set within the Cuban American community which is living in
Ybor City in Tampa, Florida (Cruz 2). Second, it is apparent that Cuban Americans prefer to
stay within their own cultural community whenever they can help it, which explains how they
have been able to keep their old traditions. Their cigar-rolling factory, for instance, is not run
in the same fashion that American companies are, what with a lector being availed to
entertain the workers – as demanded by Cuban traditions (Cruz 9). The characters in this
story are defined and destroyed against the standard of Cuban heritage.
As the play begins, the previous lector has jus.
All models are wrong. Some models are useful.—George E. P. B.docxsimonlbentley59018
All models are wrong. Some models are useful.
—George E. P. Box (1919–2013)
Statistician
Describing and explaining social phenomena is a complex task. Box’s quote speaks to the point that it is a near impossible undertaking to fully explain such systems—physical or social—using a set of models. Yet even though these models contain some error, the models nevertheless assist with illuminating how the world works and advancing social change.
The competent quantitative researcher understands the balance between making statements related to theoretical understanding of relationships and recognizing that our social systems are of such complexity that we will always have some error. The key, for the rigorous researcher, is recognizing and mitigating the error as much as possible.
As a graduate student and consumer of research, you must recognize the error that might be present within your research and the research of others.
To prepare for this Discussion:
Use the Walden Library Course Guide and Assignment Help found in this week’s Learning Resources to search for and select a quantitative article that interests you and that has social change implications.
As you read the article, reflect on George Box’s quote in the introduction for this Discussion.
For additional support, review the
Skill Builder: Independent and Dependent Variables
, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.
By Day 3
Post a very brief description (1–3 sentences) of the article you found and address the following:
1. Describe how you think the research in the article is useful (e.g., what population is it helping? What problem is it solving?).
2. Using Y=

(X) +E notation, identify the independent and dependent variables.
3. How might the research models presented be wrong? What types of error might be present in the reported research?

All Wet! Legacy of Juniper Utility has residents stewingBy Eri.docxsimonlbentley59018
All Wet!
Legacy of Juniper Utility has residents stewing
By Erin Foote Marlowe
·
·
Last Friday, a collection of men and women sat in Marion Palmateer's plush Southeast Bend living room and told a story of frustration, talking over one another and becoming increasingly angry about their understanding of the legacy of Juniper Utility and what it means to them.
These folks who gathered on Palmateer's soft white couch and chairs consider themselves the modern-day victims in the more- than-a-decade-old saga of Juniper Utility Co., a water service provider formerly owned by housing developer Jan Ward in Southeast Bend. In 2002, it was condemned by Bend for what the city said was risk of catastrophic failure.
Money and "authority" are at the core of the story now for this group, as opposed to the low water pressures of a decade ago—a problem that became so egregious that, by 2001, it became a challenge to take a shower or fill a washing machine. Water lines routinely broke down.
The people in Palmateer's living room, "a loose collection of individuals," as they call themselves, are residents of neighborhoods formerly served by Juniper Utility, including Timber Ridge, Mountain High, Tillicum Village and Nottingham Square. They are frustrated with a history they felt they had no control over but is now costing them in water bills they believe will cost them thousands more per year than they ever expected.
In 2004, homeowners association representatives from their neighborhoods signed an agreement with the city that said the owners of the roughly 700 homes of the neighborhoods would pay 100 percent of the costs associated with providing water to the neighborhoods, including making improvements to the system.
But this group of residents feels the agreement wasn't in their best interest and they had no say in the decision. An HOA board member at the time said a ballot was not sent out to homeowners for approval and, because there was no vote of homeowners, these frustrated residents believe this 2004 agreement could be illegal. Further underscoring the issue, it appears the agreement was never recorded with the county clerk's office. So, when these new people bought houses in these neighborhoods, the tab for paying to upgrade the water system didn't show up in their title searches.
"Think of the banks that lent against it," said Dan Kehoe, a resident of Mountain High who has taken a lead role in challenging the agreements between the HOAs and the city. "That's called bank fraud and people go to jail for it."
But although frustrations over this agreement are evidently fresh for these residents, it would appear that the issue should be moot because in 2011 the HOAs and the city reached a new agreement—one that should reduce costs for residents.
"We moved them from a bad agreement to a good agreement," said city of Bend Finance Director Sonia Andrews. "From something that would cost them a lot to something that would be more reasonable."

The event industry is navigating through the strongest wave of change of
the past 10 years. Never before has this industry experienced this level
of transformation in so many aspects of the event planning process.
Attendees, suppliers and event planners have to deal with ‘new’ and
‘different’ on many levels.
As a segue from last year’s report, we are again looking at the five major
areas impacted by this change:
G TECHNOLOGY
G EVENT MARKETING
G VENUES
G DESTINATIONS
G EVENT DESIGN
We are also looking at two new categories of trends:
G EVENT STYLING
G DESTINATION MANAGEMENT COMPANIES
(DMCS)
The spend for these items represent a massive input for the industry and we
feel times are mature enough to analyze developments on a yearly basis.

MACRO TRENDS AFFECTING THE
EVENT INDUSTRY. A FORECAST.
There are common themes you will find in the following categories of
trends. We refer to these as macro trends. They are inherent to the
economic, political, social and technological developments happening
around us. Here are the most significant affecting the event industry:
G Sexual Harassment. With the explosion worldwide of the #metoo
movement and the very public charges against many celebrities,
politicians and people of influence, it seems it is finally time for the event
industry to reflect on sexual harassment. Many reports have popped up
of events being at the ideal stage for harassment or violence to happen.
As a result there is increased pressure to step up the measures to protect
attendees against perpetrators. A mo.

Program Leadership and Governance
Leadership
The All of Us Research Program (AoURP) is a large collaborative initiative sponsored by the
National Institutes of Health (NIH). The research program functions as a consortium of awardees
from multiple institutions. Its governance involves representation from each awardee and
participant representatives. The consortium also includes the program director and project
scientists/specialists from NIH. Each awardee has responsibilities commensurate with expertise. See
Table 0–1: Program Unit Awardees for a list of NIH-funded awardees and contact Principal
Investigators (PIs).
Dr. Joshua Denny of Vanderbilt University Medical Center serves as the Principal Investigator on
behalf of the consortium.
Governance
The Steering Committee (SC) is the primary governing body of AoURP. The SC recommends
strategic directions for the program and oversees planning, coordination, and implementation of the
program’s overall operations. Its 50 voting members include PIs from each awardee as designated
in the notice of award; representation from NIH, comprising of the deputy director and chief
officers of AoURP; representation from community partners and participants (see section 3.1); and
additional representation as needed to ensure balanced representation of stakeholders. The
governance also includes an Executive Committee (EC) which is a small governing body composed
of 17 members, that ensures the program is effectively meeting its objectives and mission. The EC
proposes solutions to challenges and provides the Director with strategies, options, and information
to aid in programmatic decisions. The Director has discretion to delegate specific decisions to the
EC. Membership of the EC is determined by the Director and reflects the awardees within the
consortium with balanced interests to ensure effective deliberation.
The Steering Committee may appr.

Creating the ideal marketing plan requires many steps and gathering data. “Knowing the needs of the customer and having a clearly articulated mission will help to target the message to an audience who will be most interested in the service that is being provided” (Sciarra, Lynch, Adams, & Dorsey (2016) p. 340). To find these needs, a needs assessment can be done. After gathering the results, a plan can start to form. Creating a Strength, Weakness, Opportunities, and Threats chart (SWOT) will give you a broader view on how to target your population.
“The first step in conducting SWOT analysis is to identify your stakeholders and data that has already been collected” (Sciarra, (2016) p. 340). Your stakeholders will guide you into the right direction for a plan of action. Looking at the type of population including the children, families, and staff members will give you the data to create your SWOT. Moving forward with the data, now to breakdown your SWOT data analysis and create a marketing plan. Strengths; reviewing this section will give you an objective overview of any changes needing to be made. Strengths can consist of staff, location, cliental, and possibly opportunities. If there are areas of weakness this gives us the ability to make changes. Moving forward with those changes leads us to Weakness, do we see a pattern of areas? What can we do to upgrade or change these areas we have identified? Moving on next to Opportunities, what options do we have beyond what we have now? Is there room for growth both financially and structurally? Finally, Threats to evaluate. Are we looking at opening a facility next door to two other highly rated centers that may cause us competition and difficulty building a successful business? Is there a possibility that the area is losing population and economic strength? Gathering the data and taking a step back and reviewing all the pro’s and con’s will give us a bigger picture when deciding which way to market our audience.
Taking a look at the strengths from all the gathered data will give you a good direction to follow for reaching protentional public relations opportunities. For an example, location, your childcare facility has a prime location in your town and your coming up on your grand opening soon. Planning an.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

mesAll ClassesHow This API Document Is Organized
This API (Application Programming Interface) document has
pages corresponding to the items in the navigation bar,
described as follows.
Package
Each package has a page that contains a list of its classes and
interfaces, with a summary for each. This page can contain six
categories:Interfaces
(italic)ClassesEnumsExceptionsErrorsAnnotation Types
Class/Interface
Each class, interface, nested class and nested interface has its
own separate page. Each of these pages has three sections
33. consisting of a class/interface description, summary tables, and
detailed member descriptions:Class inheritance diagramDirect

descriptionNested Class SummaryField SummaryConstructor
SummaryMethod SummaryField DetailConstructor
DetailMethod Detail
Each summary entry contains the first sentence from the
detailed description for that item. The summary entries are
alphabetical, while the detailed descriptions are in the order
they appear in the source code. This preserves the logical
groupings established by the programmer.
Annotation Type
Each annotation type has its own separate page with the
following sections:Annotation Type declarationAnnotation Type
descriptionRequired Element SummaryOptional Element

Enum
Each enum has its own separate page with the following
sections:Enum declarationEnum descriptionEnum Constant

Deprecated API
The Deprecated API page lists all of the API that have been
deprecated. A deprecated API is not recommended for use,
generally due to improvements, and a replacement API is
usually given. Deprecated APIs may be removed in future
implementations.
Index
The Index contains an alphabetic list of all classes, interfaces,
constructors, methods, and fields.
Prev/Next
34. These links take you to the next or previous class, interface,
package, or related page.
Frames/No Frames
These links show and hide the HTML frames. All pages are
available with or without frames.
All Classes
The All Classes link shows all classes and interfaces except
non-static nested types.
Serialized Form
Each serializable or externalizable class has a description of its
serialization fields and methods. This information is of interest
to re-implementors, not to developers using the API. While
there is no link in the navigation bar, you can get to this
information by going to any serialized class and clicking
"Serialized Form" in the "See also" section of the class
description.
Constant Field Values
The Constant Field Values page lists the static final fields and
their values.
This help file applies to API documentation generated using the
standard doclet.

Commenting guidelines
Documenting Your Classes and Methods
It is important always to document your code clearly. For Java
programmers, some general commenting conventions have been
established by a tool called javadoc (Links to an external
site.)Links to an external site., the Java API documentation
generator. This tool can automatically extract documentation
comments from source code and generate HTML class
descriptions, like those in the Sofia API (Links to an external
site.)Links to an external site.. This tool is so popular and so
commonly used that it has set the standard for how people
document the externally visible features in their Java code. (See
the Sun article on "How to Write Doc Comments for the
Javadoc Tool" (Links to an external site.)Links to an external
site..)
JavaDoc (Links to an external site.)Links to an external site.
Comments
The javadoc tool expects comments to be written in a particular
way--other comments are ignored. JavaDoc comments (also
called just "doc comments") always start with "/**" and end
with "*/". Any other comments are ignored when generating
documentation for your code. Further, a JavaDoc comment
describing something always appears immediately before the
thing it documents.
Within a JavaDoc comment, special tags can be embedded to
signal particular kinds of information. These doc tags enable
59. complete, well-formatted API documentation to be
automatically generated from your source code. All JavaDoc
tags start with an at-sign (@).
If you already know some HTML, you can even embed simple
HTML markup inside your JavaDoc comments, and it will
appear in the generated documentation for your classes. This is
handy if you want to add bullet lists in a class description, or
wish to make part of your comment stand out in boldface, and
so on.
Describing a Class
You should place a descriptive JavaDoc comment just before
the start of each class you write:
/**
* Write a one-sentence summary of your class here.
* Follow it with additional details about its purpose, what
abstraction
* it represents, and how to use it.
*
* @author Stephen Edwards (stedwar2)
* @version 2011.01.30
*/
public class UserProfile
. . .
{
. . .
}
Class descriptions typically use two tags: @author indicates
who wrote the file, and @version indicates the "version" of this
file or project. You can use your full name, or just PID, in an
@author tag. In this course, it is fine to use the date when the
file was written as the version information in the @version tag.
When using tags like @author and @version, make sure to put
them at the beginning of the line within the doc comment.
For the @author line be sure to list your user name (PID) as
well as your first and last name. Also, if you started off with a
default comment generated by the IDE (like the example above)
60. don't forget to replace the text inside the comment with your
own. The javadoc tool will use the very first sentence of your
comment as a one-sentence summary of your class, and will use
the entire text of your comment as the full class description.
Remember that if you just write regular comments, they won't
be recognized as "official" descriptive text for document
generation:
// This comment describes what this class does, but because it
// uses //, it won't be recognized as a JavaDoc comment.
public class UserProfile
. . .
{
. . .
}
Documenting a Method
You should place a descriptive JavaDoc comment just before
each method or constructor you write:
/**
* Move the robot forward to the next HTML heading.
*/
public void advanceToNextHeading()
{
. . .
}
As with other JavaDoc comments, make sure this appears just
before the method it describes. For methods that have
parameters, you should also include a brief description of what
each parameter means. For example, we might have a
UserProfile class that provides a setter method for its name:
/**
* Set the profile's name to the given value.
*
* @param newName The new name for this profile.
*/
public void setName(String newName)
{
61. . . .
}
Here, a @param tag has been used to give a description of the
meaning and use of the parameter. Use a separate @param tag
to describe each parameter in the method (or constructor). Be
sure to start these tags at the beginning of a comment line, and
group all of the tags with the same name together (i.e., all
@param tags should be next to each other).
Again, javadoc will take the first sentence in your comment as a
one-sentence summary of what the method does. The remainder
of the comment will be used in generating a full description of
the method.
Some methods have return values--that is, they give back
information to their caller. For example, a getName() method
might return a String containing the user profile's current name.
You can document what information is returned using a @return
tag:
/**
* Get this profile's name.
*
* @return This profile's name
*/
public String getName()
{
. . .
}
Generating Your Documentation
Within an Eclipse project, you can use the Project->Generate
Javadoc... command to generate full documentation for your
own project straight from your source code. Click Next twice,
and in the final screen check to "Open generated index file in
browser" near the bottom. Once complete, a new tab will open
showing all of the generated documentation for your classes.
Other Comments in Your Code
JavaDoc comments are "public" documentation of the externally
accessible features of your classes. Often, you may also wish to
62. include "internal" (that is, private) documentation that is only
useful to someone reading the source code directly. Any
comment that does not begin with /** is treated as private,
purely for someone with access to the source code. You are free
to use such comments where ever you like to improve the
readability of your code, but ...
Internal Comments Are the Documentation Technique of Last
Resort
Choose all names carefully so that a naïve reader's first
interpretation will always be right. Do not choose names that
might mislead someone about what a method is supposed to do,
or what information a variable holds. Choosing poor names or
convoluted logic structure and then trying to explain it in
lengthy comments does little to improve readability. This is
doubly true for methods, because half the time a reader will see
your method name where it is called, not when they are reading
your method itself. If it is not immediately clear what the
method should do, that affects the readability of all the code
calling this method, no matter how many comments you put in
the method itself.
Strive to write code that is clear and understandable on its own,
simply by virtue of the names you have chosen and the structure
you use. If you feel you have to add an internal comment to
explain something, ask yourself what needs explaining. If you
need to explain what a name refers to or how you intend to use
it, consider choosing a better name. If you have to explain a
complex series of if statements or some other convoluted
structure, ask yourself (or a TA) if there is a better way. Only
after considering these alternatives should you add descriptive
comments.
Redundant Comments Are Worse Than No Comments
Consider these comments:
user = new UserProfile(); // Create a new user profile
x = x + 1; // Add one to x
63. user.setName("Ben"); // change the profile name
These are examples of useless comments. Many students add
comments to their code just to "make sure everything is
documented," or because they believe copious comments are
what the instructor is looking for. Comments like this just get in
the way of reading the code, however. You should only add
comments when they express something that isn't already
evident from the code itself. Comments are more information
that the poor reader has to wade through, so you need to
carefully balance their benefits against the cost of having to
read them. This reader might be - and often will be - you, so a
good mental model to adopt is that you are writing comments as
messages to your future self. This future you will be more
experienced than the current you when it comes to
programming, but will have forgotten the details of the code
written even a week ago. You should write your comments with
an eye towards minimizing the mental effort this future you has
to expend to be able to understand and maintain your code.

Project 3 - Play Tetris
Overview
Tetris (Links to an external site.)Links to an external site. was
arguably the most popular single-player computer game of all
time by the early 1990's. It's incredibly simple and fun to play,
and even to this day it's widely considered to be among the best
games of all time.
In case you've never seen it, the game consists of a 10-unit wide
by 24-unit tall well, into which randomly-selected geometric 4-
unit pieces begin to fall one at a time. The player manipulates
each piece as it falls, by moving it horizontally within the well,
and rotating it in 90° increments. Once the piece can fall no
further, it becomes locked in place, taking up space in the well.
However, if the player forms one or more full horizontal (10-
unit by 1-unit) rows, those rows are removed, with all rows
above shifting downward. The goal is to continue playing as
long as possible, so the player must attempt to pack the pieces
strategically. Eventually, though, the well fills upward to a
limit line, and if any portion of a piece is locked in place above
this line, the game is over.
You'll see all of this in action soon enough, and it's actually
quite easy to understand once you've played it for just a few
minutes.
Requirements
Building a full-functional Tetris application requires a little
more Java than what we've covered yet this term, so you'll be
provided a working application that you can download and
play. It's a somewhat simplified version, with a very
rudimentary scoring mechanism, but it's still just as enjoyable
and challenging as the original.
So, if the application is already provided, what is this
assignment all about? The goal here is to develop a basic
75. Artificial Intelligence ("AI") system, capable of controlling the
game as if it were the player.
Implementing an Interface
In previous assignments, you were given a class file with
method declarations, Javadoc comments, and placeholder
implementations. In this assignment, you'll be given an
interface instead. An interface contains the method declarations
and the Javadoc comments, but no code at all (not even
placeholders). Your task is to implement this interface, which
means you'll develop a class that provides code for all the
methods declared in the interface. In addition to the methods
specified by the interface, you will likely need to develop
several private helper methods in order to fully implement it
without redundancies.
System Description
The interface you will implement is called
edu.vt.cs5044.tetris.AI and your implementation class must be
called edu.vt.cs5044.TetrisAI. You will need to develop the
code needed to implement the methods defined by the interface.
One of the methods will be the overall AI system. This method
receives some parameters, defining the current state of the game
board and the shape to be placed, and will need to find the
"best" placement for that shape. The other methods are
responsible for intermediate calculations. These methods would
normally be private, and not specified by the interface, but for
academic purposes we're exposing these methods to ease the
testing requirements. Speaking of tests, your JUnit test file
must be called edu.vt.cs5044.TetrisAITest.
Downloads
tetris5044.jar library file containing all the compiled game
engine classes
tetris5044-api.jar library file containing the Javadocs for the
game engine
Setting up Eclipse
76. Download the provided files to your computer, and place them
in a convenient folder. Open Eclipse and create a new Java
Project for this assignment. Right-click the project and select
Build Path | Configure Build Path, then select the Libraries tab.
Click Add External JARs and navigate to where you placed the
downloaded JAR files, select tetris5044.jar, and click OK. You
should now see that file listed just above the JRE System
Library. Now click the little triangle to expand the new file,
select Javadoc location: (None), and click the "Edit..." button.
Here be sure to select "Javadoc in archive" first, then click
Browse. Navigate again, this time selecting tetris5044-api.jar,
and click Validate. It should tell you the location is likely
valid, so click OK, then OK, then OK to get back to your
project. Your should see a new Referenced Libraries section,
which you can expand to see the tetris5044.jar file.
Shall We Play a Game? (better than tic-tac-toe)
At this point, you can right-click your project and select Run As
| Java Application to play Tetris! Go ahead and try it now...
A window should appear with an empty game board and a
prompt to type P to play. Once you type P, you will see a new
random piece near the top, slowly falling toward the bottom of
the well. There are several alternative keyboard controls you
can use, but for now just type J and L to move the piece left and
right, and type I to rotate the piece. Once the piece is situated
as you wish, you can use K or the space bar to drop the piece
immediately, or you can just enjoy watching the piece fall
gently into place.
Zombie (brains?)
You can type '?' into the game at any time to produce a listing
in the Eclipse console of all of the available options and
keyboard controls. Some of these options will be extremely
useful during the assignment. Try that now. You'll probably
notice some interesting options, including a way to enable the
Player AI by typing Ctrl-P. When you enable this mode, just
before a new shape appears in the game, the AI is asked how to
77. best rotate then position the shape. Go ahead and attempt that
now. Nothing will happen, except you'll see a warning in the
console that your implementation couldn't be found, which is
perfectly understandable at this point.
Trying to Take Over the World (no, not that Brain)
Close the game for a moment now, while we get some of the
basics for the code in place. First, create a new package in your
src folder called edu.vt.cs5044 then right-click within that
package select New Class. Before you enter the class name,
click the "Add..." button to the right of the Interfaces section.
In the search box at the top, type AI and you should soon see
the AI interface (in the edu.vt.cs5044.tetris package) selected.
Click Ok to add that interface, and now you can enter the class
name TetrisAI and click Finish.
Notice that the new file declaration says public class TetrisAI
implements AI. This is what tells Java that we intend to be
compatible with any system that can work with the AI
interface. You'll also notice Eclipse is already showing an error
on the class declaration line. Click the tiny red X in the margin
and double-click "Add unimplemented methods" from the pop-
up. This asks Eclipse to generate all the method placeholders
for you! Save the file, and check out your implementation. It's
already compatible with the game system, even though all it
does is return placeholders. That's not very useful, of course,
but it's actually enough to get started. Let's see if it's
recognized by the game engine.
Launch the application again, type Ctrl-P to activate the Player
AI, and confirm that the console says the Player AI is now on.
If so, go ahead and type P to start the game. Well, that's not
very exciting. The console just keeps saying that the AI
selected an invalid move for each shape, and we still have to
manually place the pieces. That's fair enough, since all we have
are placeholders that Eclipse generated for us, but at least we
know the game found our AI and seems to be communicating
with it. Close the game again now so we can code a little more.
78. Let's at least provide a valid suggestion, even if it's always
exactly the same suggestion. In the findBestPlacement()
method, let's replace the placeholder:
return null;
with this:
return new Placement(Rotation.NONE, 0);
Eclipse will complain that it doesn't know about the Rotation
class yet, so again click the tiny X in the margin and double-
click to import the Rotation class from the edu.vt.cs5044
package. That should resolve the error, so save your file again.
This really doesn't seem like much of an improvement, but we'll
try it anyway.
Launch the game and use Ctrl-P then P to check it out. So, now
it's just placing everything against the left edge (column 0)
without any rotation, which is still fairly lame, but it's clear that
our AI is actually placing the pieces automatically for us!
Things can only get better from here. Close the game once
you're ready to code again.
Need More Input (accidental AI, maybe)
Obviously we need to examine the shape and the state of the
board in order to make some reasonable decisions. Let's take a
look at all those Javadocs that make up the API. In your source
file click within the word AI of "implements AI" and type Shift-
F2. This should open the Javadocs for the AI interface using an
internal browser within Eclipse. You can set it to use an
external browser, if you prefer, but this is fine for now.
Reading the Javadocs, click the findBestPlacement() method
and you'll see it actually provides a brief outline of a strategy.
We apparently need to iterate over each possible rotation, and
for each rotation we need to iterate over every possible column
placement. For each of these, we need ask the Board object to
tell us what the result of any hypothetical move would be.
Click the method Board.getResultBoard() to see how that
works. The Javadocs say that the original board instance is not
modified, and we'll get a new board instance that we can
79. examine.
That will meet our needs, but how do we examine one of these
hypothetical results? There are only a few other methods
available in the Board class. One provides a human-readable
rendering of the board, which might prove very useful to
visualize what's happening while debugging, and another
promising method seems to let us query any location within the
board to see which locations are occupied by fixed blocks.
There are also some static constants that tell us the overall size
of the board, plus two constructors. One of the constructors
allows us to generate arbitrary board configurations, which is
exactly what we'll need in order to create some nice test cases.
Click the Package link at the very top of any Javadoc page to
see the package overview, then navigate throughout the various
pages to see what each class and enum can do, along with the
requirements for the interface. A fundamental part of this
assignment is to learn how to use Javadocs to explore unknown
libraries, as well as to see how a somewhat larger scale system
is divided into multiple classes, each with its own purpose.
Note that class Tetris5044 is for internal use only; you won't
need it at all. Also, classes RandomMode and ShapeStream are
only needed for the optional "challenge" section below.
Strategy Games
There's no such thing as a perfect Tetris strategy, so we won't
even try. We are necessarily taking the heuristic (Links to an
external site.)Links to an external site. approach to this
problem, and there will necessarily be trade-offs involved. In
every placement decision, there are advantages and
disadvantages. How can we hope to find the "best" placement?
Now is probably a good time to look at those other methods in
the interface.
Costs and Benefits
From the API, it seems the remaining methods of the interface
are related to making some measurements to evaluate a board
position. The idea here is that we'll compute four distinct
80. "cost" scores, or factors, which tell our system something about
how bad (or good) a particular placement might be. We'll need
to develop those method first, before we can hope to have a
working AI system.
We're still focusing on TDD, so start with some fairly
straightforward test cases to ensure the individual scoring
methods work. Just construct a test board object, then assert
the cost score you expect your implementation to compute.
Once all of your individual cost scoring methods are working
properly as expected, its time to put it all together. The
findBestPlacement() method will need to iterate through all the
possible placements, and for each it will combine these
individual cost scores in a weighted sum, then choose the lowest
cost to return to the game engine. The weightings are important
so that certain factors can have more influence on the overall
decision than others. At first you can just set all the weights to
1, by simply summing the individual scores together, even
though eventually we'll need to adjust the weights to achieve
better results.
Strategic Default
Luck plays a starring role in Tetris. Even with the best of
strategies, it's critical to recognize that some games simply
provide a more fortunate sequence of shapes than others. Thus
it can be difficult to objectively judge exactly how good a
particular strategy might be. To help with this, our
implementation provides a set of 4 repeatable test sequences we
can use as a benchmark. The average number of pieces placed
from these 4 test sequences will act as a very reasonable metric
of how well our strategy is working overall.
Teaching to the Test
Eventually we'll be making a linear combination of our four
scores, which just means we multiply each score by some
weight, then add the weighted scores. The equation is very
straightforward:
overallCost = weight1*score1 + weight2*score2 +
weight3*score3 + weight4*score4
81. Computing the individual scores really isn't too bad, but what
about the weights? As noted above, we can start by simply
setting all the weights to 1, and indeed that strategy will place
an average of just above 100 pieces for each of the provided test
sequences.
Standards of Learning
Can we do better? Sure! As a start, reasonable weight ranges
for the selected factors will be 0 through 15. You can just use
trial-and-error if you wish; watch your AI play the test games
and try to figure out which factors need more or less emphasis.
For example, if your AI is creating too many unnecessary gaps,
try to increase the weight of the gap count score. Be sure to use
Turbo mode and all the Random TEST modes.
Your AI must be able to place at least 200 pieces, on average,
across the provided test sequences. Try adjusting your weights
in increments of 5, meaning weight values of 0, 5, 10, and 15.
Of the 256 possible combinations of 0, 5, 10, and 15 as weights,
about 10% will result in this level of performance. You don't
need to provide a JUnit test to demonstrate this performance,
but Web-CAT will check whether your system meets this
minimum or not.
More than Full Coverage
Unlike in the previous assignment, creating JUnit tests to cover
all of your code will be very straightforward, since there aren't
very many branches involved in the solution. You can likely
achieve full coverage with just one well-designed test case that
asserts something about each method. As a result, complete
coverage is not nearly enough to ensure you have correctly
implemented your code. Therefore, you must generate at least 5
test cases for each interface method, with non-trivial tests and
non-trivial assertions. You can satisfy this by creating at least
5 distinct test boards to be shared among assertions involving
all methods. Just be sure the test boards cover a reasonably
wide range of scenarios. Note that Web-CAT won't (and can't)
enforce this requirement, but the human grader will definitely
be looking for this.
82. Functional Decomposition
Judicious use of helper methods can significantly reduce the
overall amount of code you need to develop. For example, you
might want to create a helper method that returns the height of
one specified column. You can then call that method from
within a loop of all columns, and use the return value to help
compute some of the cost factors your. Your code will be
inspected during the human review for redundancies, so be sure
to develop helper methods wherever appropriate.
Automating the Automation
You might have noticed that it can get somewhat tedious to try
every combination of 0, 5, 10, and 15 for each of the weights,
even in Turbo mode. You might have also noticed that you've
been given sufficient tools to run entire simulated games
without the user interface at all.
As a challenge, see if you can identify the very best
combination of 0, 5, 10, and 15 weights, by writing a separate
class file called edu.vt.cs5044.WeightFinder with its own
main() method. This file will be completely ignored by Web-
CAT, and you don't need to generate any tests for it at all.
You'll also need to add a public method, such as setWeights(int
w1, int w2, int w3, int w4) to your TetrisAI implementation, to
apply the various weight combinations. This method will need
to be exercised by a single assert, just to be sure it's covered
within your own JUnit tests.
Once you've found the optimum combination, you'll need to
hard-code those values back into your AI as the defaults, in
order to watch them in action. The best weights among these
combinations will place an average of over 480 pieces for the
test sequences. That's quite an improvement, unless you
happened to get very lucky in your trial and error phase!
Confirm that this is all working as expected, and that you're
placing 480+ pieces on average for the test sequences before the
next part of the challenge. It should be a simple change to your
code to try stepping by 3 instead of 5 (meaning you should test
every combination of 0, 3, 6, 9, 12, and 15 for every weight).
83. This process takes about 5-10 times longer to run than stepping
by 5. However, if everything was already working properly,
you'll only need to do this once, and you'll discover that your
newly-tuned weights will average over 1,900 pieces placed for
the test sequences. We'll call that a definite win!
Still not satisfied? You can always try stepping by 1 instead.
Again it's a trivial code change, but note that this process takes
about 50-100 times longer to run than stepping by 3, so we're
likely talking about a few hours at this point. However, your
newly-optimized AI possess the astonishing capability of
averaging over 6,100 pieces placed for the test sequences! You
might be somewhat amazed when you discover the optimum
weightings. Also, you're in for a bit of a surprise when you
watch this in action, specifically comparing the results of the
TEST1 sequence to those of the TEST2 sequence.
If you make any progress with this OPTIONAL challenge,
please add a brief write-up in the comments of your
WeightFinder class, just to let us know what you did, along with
any thoughts you'd like to share about the experience. Of
course you may also discuss this in Piazza, although please
don't post your code (or any weightings you find) to the entire
class, so as not to spoil the fun for anyone else.
Hopefully you enjoyed this challenge!
Submit to Web-CAT
Submit your solution to Web-CAT (Links to an external
site.)Links to an external site. via Eclipse or the web interface.
Please feel free to improve and resubmit your code as many
times as you like (before the deadline) in order to improve your
score.
Important Notes:
· Your submission will be evaluated both by Web-CAT (40
points) and by human (40 points). As such, Web-CAT's
automated score will show at most 40/80 points.
· Your JUnit test class will be evaluated by Web-CAT to ensure
complete coverage of you implementation code, but it will NOT
be evaluated for style. Web-CAT will also use its own internal
84. test suite (that we've developed) to evaluate your system.
· Carefully review your feedback. In the summary, you will see
a table listing each of your source files with a green/red bar by
each non-test file. If the bar for any file is not completely
green, then some code in that file was not exercised by your
own tests. Click the file name to view your source code and
look for lines that are highlighted in a pink color. Hover your
mouse over highlighted lines for additional information. You
will need to add at least one test case to exercise the highlighted
code. This includes testing the same actions you've already
tested, but starting from different initial conditions.

Object-Oriented Programming with Java
Q&A Session
Midterm Exam
• Exam is split into three parts, all due Monday (7/3) at noon ET
– Each part has a 30 minute time limit for 20 multiple-choice
questions
– Each part covers a cross-section of all materials from Module
1 through Module 5
– See also Piazza @166 (and posts linked from there) for a few
more details
85. Project 3 - Play Tetris
• Tetris!
– We've been tasked to develop an artificial intelligence (AI)
that can play Tetris
• An "interface" has been provided; you will implement the
interface
– We'll learn more about interfaces in several weeks, but for
now:
• An interface is just a way in Java to specify required methods,
without any code
• To implement the interface, we develop a class with actual
code in these methods
– Eclipse can generate the placeholder methods for us
automatically
• Once that's done, it becomes just like our previous projects
• Plus, the compiler will ensure we don't accidentally change
the method headers
Meet the Cast of Players
• enum Shape
– One value for each of the seven geometric pieces involved:
– Each Shape provides a set of distinct Rotation values (default
orientations shown above)
– You can also request the width of the shape (in blocks) after
applying any valid Rotation
• enum Rotation
– One value for each 90° rotation:
86. • NONE
• CCW_90
• CCW_180
• CCW_270
Game On
• class Placement
– A Placement just holds a Rotation value and a column number
together
– This is what our AI needs to return to the game engine, for
any Shape:
• First the Rotation will be applied to the Shape
• Then the rotated Shape will be moved horizontally
– The left-most block will be placed in the specified column
– Invalid Placement objects will be rejected (and ignored) by
the game engine
• class Board
– Represents the state of the playing board at any given time
– Provides static int values: WIDTH, HEIGHT, and
HEIGHT_LIMIT
– Contains a collection of fixed blocks; allows us to query via
isBlockAt(col, row)
– We can ask the board to show us the hypothetical result of
placing another piece
• The piece will be placed and dropped, then any full rows will
be cleared
• Creates a new Board object; does not mutate the existing
Board
87. – We can also construct new Board objects with arbitrary blocks
for testing
• ShapeStream and RandomMode are only used for the optional
challenge
• Tetris5044 is for internal use only, by the game engine itself
Mind Games
• interface AI
– This is what we need to implement!
– public Placement findBestPlacement(Board currentBoard,
Shape shape)
• This is how the game engine asks our AI what to do
– The remaining methods need to compute "cost" factors for a
given board:
• int getColumnHeightVariability(Board board)
• int getMaximumBlockHeight(Board board)
• int getTotalBlockCount(Board board)
• int getTotalGapCount(Board board)
• Academic Note: Normally these would be private, and not
required by the interface
– The individual cost factor methods should be developed (and
tested!) first
– Once you've completed at least one cost factor method, to find
the best placement:
• For every possible placement of this shape
– Get the board that would result from this placement
– Calculate cost factors for result board and combine with
weights
– If this is the lowest overall cost so far, consider this
88. placement as the new best
• Return the best placement to the game engine
– Adjust the weights to meet minimum average performance
requirements in TEST modes
