Java questionI am having issues returning the score sort in numeri.pdf
Java question
I am having issues returning the score sort in numerical order for more than 2 entries. I had to
develop an enhancement which allowed the application to sort the list by score. The easiest
solution is probably to create a second student class (perhaps called StudentScore) that
implements the IComparable interface to sort by score rather than by name
StudentSortApp
import java.util.*;
public class StudentSortApp
{
public static void main(String[] args)
{
System.out.println(\"Welcome to the Student Scores Application.\"+\"\ \");
Scanner sc = new Scanner(System.in);
System.out.print(\"Enter number of students to enter: \");
int numberofStudents = sc.nextInt();
//arrays storing student name and score
Student[] students = new Student[numberofStudents];
StudentScore [] studentScores = new StudentScore [numberofStudents];
int t = 0;
for (int i = 0; i < numberofStudents; i++)
{
System.out.println(\"\");
String studentLastName = Validator.lastName(sc, \"Student \" + (i+1) + \" Last name: \");
String studentFirstName = Validator.lastName(sc, \"Student \" + (i+1) + \" First name: \");
int studentScore = Validator.validScore(sc, \"Student \" + (i+1) + \" score : \");
students [t] = new Student(studentFirstName, studentLastName , studentScore);
studentScores [t] = new StudentScore(studentFirstName, studentLastName , studentScore);
t = t + 1;
}
//output
System.out.println(\"\");
System.out.println(\"Last Name Sort\");
Arrays.sort(students, 0, numberofStudents);
for(Student i: students)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
System.out.println();
System.out.println(\"Score Sort\");
Arrays.sort(studentScores, 0, numberofStudents);
for(StudentScore i: studentScores)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
}
}

public static int validScore(Scanner sc, String prompt)

if (studentScore > 100 || studentScore < 0)
{
System.out.println(\"Error! You have to enter a score between 0 and 100\");
}

HELP IN JAVACreate a main method and use these input files to tes.pdf
For the questions below, use the W3Schools customer orders database. You need to submit
thoroughly tested SQL statements. For your convenience and reference, relevant data model is
attached as a PDF document with the assignment in the Blackboard. Name of this document is
\"Relationship diagram for W3schools order pdf.\" 1) Write a query to show Customers\' Country
wise sales totals. Your query should show Customers\' Country name and the total sale value for
that Country 2) Write a query to show Product wise sales totals. Your query should Product
name and the total sale value for that Product. 3) Write a query to show the number of orders for
each shipper. Your query should show shipper name and the count of orders with the shipper. 4)
Write a query to show number of products in each product category. Your query should show
Category name and number of products in that category 5) Write a query that shows Customers\'
country wise customer count, and order count. Your query should show country name, total
number of customers from that country, and total number of orders from the customers of that
country 6) Write a query that shows the number of products supplied by each Supplier. Your
query should show Country name, supplier name and the count of products supplied by that
supplier. Note: Sale Price Orderdetails.Quantity Products.price (see an example in the class
slides deck) W3SCHOOLS SQL is located at http://www.w3schools.com/sql/default.asp
(Preferred browser is Chrome). On this page you will find a button called \"Try it yourself\".
Click on that button. You will be redirected to a page where you see a list of tables on the right
side of the page. It is highly recommended to click \'Restore Database\' button on this page
during every session. The page contains a box where you can type in an SQL statement
involving the listed tables. You type in your SQL statement in that box and click on \"Run
SQL\'\' button. The results will be displayed if your SQL statement is syntactically correct.
Solution
1. SELECT Customers.Country, SUM(OrderDetails.Quantity * Products.Price) AS Total_Sale
FROM Customers
LEFT JOIN Orders ON Customers.CustomerID=Orders.CustomerID
LEFT JOIN OrderDetails ON Orders.OrderId=OrderDetails.OrderId
LEFT JOIN Products ON OrderDetails.ProductId=Products.ProductId
Group BY Customers.Country;
2. SELECT Products.ProductName, SUM(OrderDetails.Quantity * Products.Price) AS
Total_Sale FROM Customers
LEFT JOIN Orders ON Customers.CustomerID=Orders.CustomerID
LEFT JOIN OrderDetails ON Orders.OrderId=OrderDetails.OrderId
LEFT JOIN Products ON OrderDetails.ProductId=Products.ProductId
Group BY Products.ProductName;
You can edit these query to get other results set..

The next step is to add method calls for the accessor methods after each input:
//Reading and updating values
System.out.print(\"\ Enter Person Name: \");
person1.setPersonName(sc.nextLine());
System.out.println(\"You entered: \" + person1.getPersonName());
Call the accessor function each time you ask for input, after capturing that input. Then repeat for
a second Person, only this time call the constructor that takes the student id as a parameter.

Java questionI am having issues returning the score sort in numeri.pdf
Java question
I am having issues returning the score sort in numerical order for more than 2 entries. I had to
develop an enhancement which allowed the application to sort the list by score. The easiest
solution is probably to create a second student class (perhaps called StudentScore) that
implements the IComparable interface to sort by score rather than by name
StudentSortApp
import java.util.*;
public class StudentSortApp
{
public static void main(String[] args)
{
System.out.println(\"Welcome to the Student Scores Application.\"+\"\ \");
Scanner sc = new Scanner(System.in);
System.out.print(\"Enter number of students to enter: \");
int numberofStudents = sc.nextInt();
//arrays storing student name and score
Student[] students = new Student[numberofStudents];
StudentScore [] studentScores = new StudentScore [numberofStudents];
int t = 0;
for (int i = 0; i < numberofStudents; i++)
{
System.out.println(\"\");
String studentLastName = Validator.lastName(sc, \"Student \" + (i+1) + \" Last name: \");
String studentFirstName = Validator.lastName(sc, \"Student \" + (i+1) + \" First name: \");
int studentScore = Validator.validScore(sc, \"Student \" + (i+1) + \" score : \");
students [t] = new Student(studentFirstName, studentLastName , studentScore);
studentScores [t] = new StudentScore(studentFirstName, studentLastName , studentScore);
t = t + 1;
}
//output
System.out.println(\"\");
System.out.println(\"Last Name Sort\");
Arrays.sort(students, 0, numberofStudents);
for(Student i: students)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
System.out.println();
System.out.println(\"Score Sort\");
Arrays.sort(studentScores, 0, numberofStudents);
for(StudentScore i: studentScores)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
}
}

public static int validScore(Scanner sc, String prompt)

if (studentScore > 100 || studentScore < 0)
{

HELP IN JAVACreate a main method and use these input files to tes.pdf
For the questions below, use the W3Schools customer orders database. You need to submit
thoroughly tested SQL statements. For your convenience and reference, relevant data model is
attached as a PDF document with the assignment in the Blackboard. Name of this document is
\"Relationship diagram for W3schools order pdf.\" 1) Write a query to show Customers\' Country
wise sales totals. Your query should show Customers\' Country name and the total sale value for
that Country 2) Write a query to show Product wise sales totals. Your query should Product
name and the total sale value for that Product. 3) Write a query to show the number of orders for
each shipper. Your query should show shipper name and the count of orders with the shipper. 4)
Write a query to show number of products in each product category. Your query should show
Category name and number of products in that category 5) Write a query that shows Customers\'
country wise customer count, and order count. Your query should show country name, total
number of customers from that country, and total number of orders from the customers of that
country 6) Write a query that shows the number of products supplied by each Supplier. Your
query should show Country name, supplier name and the count of products supplied by that
supplier. Note: Sale Price Orderdetails.Quantity Products.price (see an example in the class
slides deck) W3SCHOOLS SQL is located at http://www.w3schools.com/sql/default.asp
(Preferred browser is Chrome). On this page you will find a button called \"Try it yourself\".
Click on that button. You will be redirected to a page where you see a list of tables on the right
side of the page. It is highly recommended to click \'Restore Database\' button on this page
during every session. The page contains a box where you can type in an SQL statement
involving the listed tables. You type in your SQL statement in that box and click on \"Run
SQL\'\' button. The results will be displayed if your SQL statement is syntactically correct.
Solution
1. SELECT Customers.Country, SUM(OrderDetails.Quantity * Products.Price) AS Total_Sale
FROM Customers
LEFT JOIN Orders ON Customers.CustomerID=Orders.CustomerID
LEFT JOIN OrderDetails ON Orders.OrderId=OrderDetails.OrderId
LEFT JOIN Products ON OrderDetails.ProductId=Products.ProductId
Group BY Customers.Country;
2. SELECT Products.ProductName, SUM(OrderDetails.Quantity * Products.Price) AS
Total_Sale FROM Customers
LEFT JOIN Orders ON Customers.CustomerID=Orders.CustomerID
LEFT JOIN OrderDetails ON Orders.OrderId=OrderDetails.OrderId
LEFT JOIN Products ON OrderDetails.ProductId=Products.ProductId
Group BY Products.ProductName;
You can edit these query to get other results set..

The next step is to add method calls for the accessor methods after each input:
//Reading and updating values
System.out.print(\"\ Enter Person Name: \");
person1.setPersonName(sc.nextLine());
System.out.println(\"You entered: \" + person1.getPersonName());
Call the accessor function each time you ask for input, after capturing that input. Then repeat for
a second Person, only this time call the constructor that takes the student id as a parameter.

Statistics is the mathematical science involving the collection, ana.pdf
Statistics is the mathematical science involving the collection, analysis and interpretation of data.
A number of specialties have evolved to apply statistical theory and methods to various
disciplines. Certain topics have \"statistical\" in their name but relate to manipulations of
probability distributions rather than to statistical analysis.
· Actuarial science is the discipline that applies mathematical and statistical methods to
assess risk in the insurance and financeindustries.
· Astrostatistics is the discipline that applies statistical analysis to the understanding of
astronomical data.
· Biostatistics is a branch of biology that studies biological phenomena and observations by
means of statistical analysis, and includes medical statistics.
· Business analytics is a rapidly developing business process that applies statistical methods
to data sets (often very large) to develop new insights and understanding of business
performance & opportunities
· Chemometrics is the science of relating measurements made on a chemical system or
process to the state of the system via application of mathematical or statistical methods.
· Demography is the statistical study of all populations. It can be a very general science that
can be applied to any kind of dynamic population, that is, one that changes over time or space.
· Econometrics is a branch of economics that applies statistical methods to the empirical
study of economic theories and relationships.
· Environmental statistics is the application of statistical methods to environmental science.
Weather, climate, air and water quality are included, as are studies of plant and animal
populations.
· Epidemiology is the study of factors affecting the health and illness of populations, and
serves as the foundation and logic of interventions made in the interest of public health and
preventive medicine.
· Geostatistics is a branch of geography that deals with the analysis of data from disciplines
such as petroleum geology, hydrogeology, hydrology, meteorology,oceanography, geochemistry,
geography.
· Machine Learning
· Operations research (or Operational Research) is an interdisciplinary branch of applied
mathematics and formal science that uses methods such as mathematical modeling, statistics, and
algorithms to arrive at optimal or near optimal solutions to complex problems.
· Population ecology is a sub-field of ecology that deals with the dynamics of species
populations and how these populations interact with the environment.
· Psychometric is the theory and technique of educational and psychological measurement
of knowledge, abilities, attitudes, and personality traits.
· Quality control reviews the factors involved in manufacturing and production; it can make
use of statistical sampling of product items to aid decisions in process control or in accepting
deliveries.
· Quantitative psychology is the science of statistically explaining and changing mental
processes and behaviors in humans.
· Reliabi.
Secondary phloemApples (Malus communis, M. pumila, & M. sylvestr.pdf
Secondary phloem
Apples (Malus communis, M. pumila, & M. sylvestris), pears (Pyrus communis) and quince
(Cydonia oblonga) belong to the rose family (Rosaceae), and include literally hundreds of
cultivated varieties. In the apple, the original ancestral species is obscured by so many cultivated
variations throughout the centuries that some authors lump them all into one species, Malus
domestica. They all originated in western Asia (or Eurasia) and are characterized by fleshy fruits
called pomes. In the pome, a thick, fleshy hypanthium layer (also called the floral cup or calyx
tube) surrounds (and is fused with) the seed-bearing ovary or core. The sepals, petals and
stamens arise from the rim of the hypanthium. Since the ovary is situated below the attachment
of the sepals, petals and stamens, it is termed \"inferior\" in technical plant taxonomy books. The
fleshy hypanthium of a rose (Rosa) surrounds a cluster of small one-seeded achenes. Since the
achenes represent separate ripened ovaries all derived from a single flower, the entire structure
(called a rose hip) can be considered an aggregate fruit or etaerio. Rose hips are eaten raw and
are ground up as a supplemental source of vitamin C (ascorbic acid).
Bing cherries (Prunus avium) showing the long stalk (pedicel) and fleshy drupe containng a hard,
stony, seed-bearing endocarp. Sweet cherries such as these are usually considered to belong to P.
avium, while sour cherries belong to the P. cerasus group. There are literally hundreds of
varieties of cherries. Maraschino cherries are made from sweet cherries which have been
bleached, deseeded, and soaked in a sugar solution to which red food coloring and flavoring have
been added. Maraschino cherries are commonly covered with chocolate, placed as a decorative
topping in ice cream sundies, and in mixed drinks.
The raspberry or hindberry is the edible fruit of a multitude of plant species in the genus Rubus,
most of which are in the subgenusIdaeobatus; the name also applies to these plants themselves.
Raspberries are perennial, with woody stems.
Raspberries are grown for the fresh fruit market and for commercial processing into individually
quick frozen (IQF) fruit, purée, juice, or as dried fruit used in a variety of grocery products.
Traditionally, raspberries were a mid-summer crop, but with new technology, cultivars, and
transportation, they can now be obtained year-round. Raspberries need ample sun and water for
optimal development. Raspberries thrive in well-drained soil with a pH of between 6 and 7 with
ample organic matter to assist in retaining water. While moisture is essential, wet and heavy soils
or excess irrigation can bring on Phytophthora root rot which is one of the most serious pest
problems facing red raspberry. As a cultivated plant in moist temperate regions, it is easy to grow
and has a tendency to spread unless pruned. Escaped raspberries frequently appear as garden
weeds, spread by seeds found in bird droppings.

Iterative solution is more efficient than recursive. The iterative solution do not compute the same
values again and again as recursive solution. Also because we are not using recursion the os

Matter is made up of electrically charge particle but the Constituents of objects have opposite
charges, adding up to electric neutrality overall. Think of it in this way that two bring two
nucleus very close together we need a lot of energy because when we talk about nucleus it\'s only
the +ve(protons) charge we are talking about. That is why the fusion of two atoms is very tough
task. But in case of atoms or molecules that are the smallest entity of matter that can individually
exist; it always contain equal number of proton and electron and hence are electrically neutral on

test fixture is to ensure that there is a well-known and fixed environment in which tests are run so
that results are repeatable
Test Suites
A test suite bundles a few unit test cases and runs them together. In JUnit, both @RunWith and
@Suite annotation are used to run the suite test.
Test Runners
Test runner is used for executing the test cases. Here is an example that assumes the test class
TestJunit already exists.
JUnit Classes
JUnit classes are important classes, used in writing and testing JUnits. Some of the important
classes are
Assert Contains a set of assert methods.
TestCase Contains a test case that defines the fixture to run multiple tests.
TestResult Contains methods to collect the results of executing a test case.

Go with the most obvious one first...Carboxylic Acids will have a.pdf
Go with the most obvious one first...
Carboxylic Acids: will have a really broad and large absorption range in the 3500-2500cm-1 area
(aka. the \"valley of the acid\") as well as a carbonyl peak in the 1700cm-1 area. That would be
spectrum 4.
Alcohols:will also have a strong and broad absorption in the 3500-3000cm-1 region, but nowhere
near as broad as the acid. It just looks like a really fat absorption line, rather than a well...
Anyway, the characteristic spectrum for the alcohol is spectrum 5.
Amines:lucky for you, the amine given in this question is a primary amine. There\'s going to be
two N-H stretching peaks in the 3300cm-1 region. There\'s also no carbonyl on the structure
given, so there should be no C=O stretching at 1700cm-1.This is spectrum 3. Don\'t worry about
the small absorption in the 1500-1700cm-1 area.
Now for the fine details...
The ester and aldehyde spectra are pretty similar, but aldehydes absorb at around 2750cm-1. It\'s
not totally clear on the spectra in the question but it looks like there\'s a 2750cm-1 absorption in
spectrum 2, so I\'d say that spectrum 2 is the aldehyde, and spectrum 1 is the ester.
Summary:
Spectrum 1 = structure B
Spectrum 2 = structure E
Spectrum 3 = structure C
Spectrum 4 = structure D
Spectrum 5 = structure A

Flexible benefit plans gives employees a choice between qualified be.pdf
Flexible benefit plans gives employees a choice between qualified benefits (non taxable) and
cash. An example of qualified benefits is medical plans. Flexible benefit plans includes health
insurance and retirement benefits.
The 2 main types of flexible benefit plans are cafeteria plans and flexible spending accounts.
Under the cafeteria plan, employees have the option of choosing from several different benefit
packages. Employees can select the option of receiving some or all of the employer\'s nontaxable
benefits or receiving cash or other taxable benefits.
The benefits offered under cafeteria plans are health and group insurance, medical
reimbursement schemes for non-insured expenses and vacation days.
Flexible spending accounts (FSA) is another prevalant flexible benefit plan. FSA is a tax
deferred savings account. These accounts are formed by employers and helps the employee in
meeting certain medical expenses that are not a part of employer\'s insurance plan.

Classification of organisms is based upon a number of physical and p.pdf
Classification of organisms is based upon a number of physical and physiological features. The
structure and organization of reproductive organs remains in important feature usually used to
distinguish organisms. Some of the features can be discussed as below:
1. Fruiting body: A very broad classification can be made on the basis whether the fruiting body
is present or not. Presence of a fleshy or modified cover around the seed is a characteristic
feature of angiosperms whereas a naked seed located directly above a vegetative structure of a
plant is a feature of gymnosperms.
2. Spores sacs: Spore releasing sacs are characteristic features found on the lower scales of the
leaf blades of lower and higher ferns. Their arrangement and mode of release determines the
nature, frequency and ease of sexual reproduction in these lower plants.
3. Pollens: Higher plants, including both angiosperms and gymnosperms utilize pollen grains for
sexual reproduction. The mode of transfer of pollen determines the geographical range of
pollination in plants. Sulphur shower is a critical example for sexual reproduction in pines
(gymnosperms) which distinguishes them from other trees.
4. Sporocarp: A sporocarp or a fruiting body is a bulging of the vegetative extension from the
main structure of a lower fungi which contains a group of cells which either follow meiotic
division or mitotic division and serve as the reproductive structures. Their growth and nature can
be monitored microscopically and the fungus can be thus classified appropriately. Some algae
also contain a unique localization and arrangement of haploid cells called spores which can be
present in singles or doublets and thus represent a very unique discrimination from other
organisms.
These, these set of information provide an insight into usability of features of a reproductive
structure for classification of organisms.

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.
Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
