Solution
Hi,
I have modified the code. it is working as expected now. Highlighted the code changes below.
Issue here is with you have written this statement twice System.out.println(x); which causes the
issue.
Program.java
import java.util.*;
public class Program
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String x=\"X\";
int amount;
System.out.println(\"Enter amount\");
amount=input.nextInt();
System.out.println(\"Amount is: \"+amount);
for(int i=1; i<=amount; i++)
{
System.out.println();
for(int j=1; j<=i; j++)
{
System.out.print(x);
}
}
}
}
Output:
Enter amount
10
Amount is: 10
X
XX
XXX
XXXX
XXXXX
XXXXXX
XXXXXXX
XXXXXXXX
XXXXXXXXX
XXXXXXXXXX.

Hello, I need some assistance in writing a java program THAT MUST USE STACKS (LIFO).
Create a Calculator w/ GUI
Write a program that graphically displays a working calculator for simple infix expressions that
consist of: single-digit operands, the operators: +, -, *, and /, and parentheses.
Make the following assumptions:
unary operators (e.g. -2) are illegal
all operations, including division, are integer operations (and results are integers)
the input expression contains no embedded spaces and no illegal characters
the input expression is a syntactically correct infix expression
division by zero will not occur (consider how you can remove this restriction)
Create a GUI application, the calculator has a display and a keypad of 20 keys, which are
arranged as follows:
C
<
Q
/
7
8
9
*
4
5
6
-
1
2
3
+
0
(
)
=
As the user presses keys to enter an infix expression, the corresponding characters appear in the
display. The C (Clear) key erases all input entered so far; the < (Backspace) key erases the last
character entered. When the user presses the = key, the expression is evaluated and the result
appended to the right end of the expression in the display window. The user can then press C and
enter another expression. If the user presses the Q (Quit) key, the calculator ceases operation and
is erased from the screen.

TOPIC- Landslide early warning in Costa Rica- Students are required to (1).docx
TOPIC: Landslide early warning in Costa Rica.
Students are required to read the article for the corresponding week and elaborate on these three core elements:
Organizational Readiness, Contingency Strategies, and Incident Response.
Students will then elaborate, if they were a consultant how would they advise the organization or element how to move forward to better prepare for the next incident, touch on all three core elements stated above.
Solution
Landslide early warning in Costa Rica:
As a consultant to the the organization i suggest to counsel the people to be prepared and alert during landslides. We need to prepare them to move to the rehabilation centers provided.
To Establish Rehabilitation centers when heavy rains occur and large number of people must be moved to the centers.
To consider the food ,water,medical facilties in the rehabilitation centers.
I need to consider the hygenic conditions and provide electricity.
To establish help line numbers.
To take safety measures in the areas which are prone to land slides where a mass of people are involved like schools and other public areas.
All the relevant sectors must involve in all the aspects to implement and monitor the activites.
We also need to be ready with rescue system to clear the land slides and to help the people back to home.
Organization must collect funds to distribute to people who are largely afftected in the landslide who may loss their shelters.
Organizations must conduct awareness camps in schools,colleges and other organzations to involve in the activities.
Awareness camps must be conducted for women and children on how to respond for the disasters.
Government must take measures to predict the land slides and to move people from the locations prior and also they should not permit people to live in such areas.

Solution
Hi,
I have modified the code. it is working as expected now. Highlighted the code changes below.
Issue here is with you have written this statement twice System.out.println(x); which causes the
issue.
Program.java
import java.util.*;
public class Program
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String x=\"X\";
int amount;
System.out.println(\"Enter amount\");
amount=input.nextInt();
System.out.println(\"Amount is: \"+amount);
for(int i=1; i<=amount; i++)
{
System.out.println();
for(int j=1; j<=i; j++)
{
System.out.print(x);
}
}
}
}
Output:
Enter amount
10
Amount is: 10
X
XX
XXX
XXXX
XXXXX

Tones Company purchased a warehouse in a downtown district where land.docx
Tones Company purchased a warehouse in a downtown district where land values are rapidly increasing. Gerald Carter, controller, and Wilma Ankara, financial vice president, are trying to allocate the cost of the purchase between the land and the building. Noting that depreciation can be taken only on the building, Carter favors placing a very high proportion of the cost on the warehouse itself, thus reducing taxable income and income taxes. Ankara, his supervisor, argues that the allocation should recognize the increasing value of the land, regardless of the depreciation potential of the warehouse. Besides, she says, net income is negatively impacted by additional depreciation and will cause the company\'s stock price to go down.
Who are the direct and indirect stakeholders and how are they affected? Is what Gerald is suggesting ethical?
Solution
Direct stakeholders: Finance controller, financial vice president and other finance staff who are involved in the fixed asset valuation who are directly involved in the process, top management of the company. It will affect the direct stakeholders in the following way: 1. Going against his / her professional ethics and morals 2. Legal issues which a person can face for saving taxes and window dressing the books of accounts 3. Loss of job Indirect stakeholders: Other employees of the organisation, customers, suppliers and the company as a whole. It will affect the indirect stakeholders in the following way: 1. Loss of company goodwill 2. Loss of consumers 3. Overall affect may lead to employees using their job Gerald is suggesting to inflate the value of the building so that they can save tax which is not ethical. The company should opt for tax planning and not tax saving through illegal means.

Toms construction site has a pipe that discharges run off from the sit.docx
Tom’s construction site has a pipe that discharges run off from the site to a small stream behind it.
Question: What information would you need before you could determine if Tom requires an NPDES permit?
Solution
The Clean Water Act prohibits anybody from discharging \"pollutants\" through a \"point source\" into a \"water of the United States\" unless they have an NPDES permit. The permit will contain limits on what you can discharge, monitoring and reporting requirements, and other provisions to ensure that the discharge does not hurt water quality or people\'s health. In essence, the permit translates general requirements of the Clean Water Act into specific provisions tailored to the operations of each person discharging pollutants.
( The term point source is also defined very broadly in the Clean Water Act because it has been through 25 years of litigation. It means any discernible, confined and discrete conveyance, such as a pipe, ditch, channel, tunnel, conduit, discrete fissure, or container. It also includes vessels or other floating craft from which pollutants are or may be discharged. By law, the term \"point source\" also includes concentrated animal feeding operations, which are places where animals are confined and fed. By law, agricultural stormwater discharges and return flows from irrigated agriculture are not \"point sources\" ).

True or False- In a proprietary system- a commercial vendor opens thei.docx
True or False? In a proprietary system, a commercial vendor opens their technology to other companies. True False What is network bandwidth? What is a domain name server?
Solution
7) Is a proprietary system a commercial vendor opens their technology to other companies
Ans-
False
8)
Ans
Network bandwidth is usually expressed in bits per second (bps); modern networks typically have speeds measured in the millions of bits per second (megabits per second, or Mbps) or billions of bits per second (gigabits per second, or Gbps).
9)
Ans
Domain Name Servers (DNS) are the Internet\'s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.

N is the president of a large department store in Country X and is also actively involved in civic, business, social and charitable activities in Country X. Concerned about a recent military coup in Country X, N accepts his opportunity to obtain a green card and he visits the U.S. on May 10,2015 to get his card. Unfortunately, N is killed in an automobile accident in the U.S. on May 15,2015 before his scheduled October 1, 2015 return to Country X. N is a resident decedent for U.S. estate tax purposes.
2 . A (a U.S. citizen), B (an NRA), FlaCo (a Florida Corporation), and FCo (a foreign corporation) each own 1/4 interest in a Florida general partnership which is involved in real estate development. In years 2011 through 2014, the partnership generates a $100,000 operating loss and each partner files its appropriate U.S. income tax returns to record its respective losses. In 2015, the partnership generates effectively connected taxable income (\"ECTI\") of $400,000 and each partner has $100,000 of ECTI allocated to it. Even though both B (an NRA) and FCo (a foreign corporation) have sufficient losses to offset the 2015 ECTI, under the general rule, the partnership must withhold U.S. income tax with respect to their 2015 ECTI.
Solution
Answer 1 is false as decedent is the non resident alien individual had no tangible property in U.S.
Answer 2 is true, any member who is non resident of the state and have income from the state, the partnership must withhold the US income tax which a partner can get the refunded after filing their return.

True or False Explain Why- 1- SIP and RTP are protocols used to allow.docx
True or False Explain Why:
1- SIP and RTP are protocols used to allow communication between users over IP.
Solution
True
SIP( Session Initiation Protocol ) is a communication protocol which is used for voice, video calls and also for instant messaging over the IP networks. It is responsible for establishment and termination of a voice call sessions between the two end points. These session include telephone calls, internet multimedia conference and multimedia distribution. It also provide authentification of caller and callee. It also identifes the number of caller and callee. It is working independent over transport layer protocol. It runs over the TCP(transmission control protocol) and UDP(user datagram protocol).
RTP(Real-time transport protocol) is a network protocol which is used to deliver audio and video over Internet protocol. It is used to manage real time transmission of multimedia data over unicast or multicast network. It also monitors data delivery for large multicast networks which allows the receiver to detect if any packet loss. It uses sequence number to detect the packet loss.

Trace the evolution of the US police system from the --political-- era.docx
Trace the evolution of the US police system from the \"political\" era to the present.
Solution
The development of policing in the United States closely followed the development of policing in England. In the early colonies policing took two forms. It was both informal and communal, which is referred to as the Watch, or private for profit policing, which is called The Big Stick.
The modern police organizations shared similar characteristics: (1) they were publicly supported and bureaucratic in form; (2) police officers were full-time employees, not community volunteers or case-by-case fee retainers; (3) departments had permanent and fixed rules and procedures, and employment as a police officers was continuous; (4) police departments were accountable to a central governmental authority.
Modern police forces in the United States emerged as a response to disorder. What constitutes social and public order depends largely on who is defining those terms, and in the cities of 19th century America they were defined by the mercantile interests, who through taxes and political influence supported the development of bureaucratic policing institutions. These economic interests had a greater interest in social control than crime control. Private and for profit policing was too disorganized and too crime specific in form to fulfill these needs. The emerging commercial elites needed a mechanism to insure a stable and orderly work force, a stable and orderly environment for the conduct of business, and the maintenance of what they referred to as the \"collective good\". These mercantile interests also wanted to divest themselves of the cost of protecting their own enterprises, transferring those costs from the private sector to the state.

Solution
The various skills that are necessary for an employee of a large corporation include:
All the above factors are of utmost importance for an employee to receive and get benefitted from senstivity training.
A large corporation is very likely to operate across different locations having different traditions, culture and values. Thus, an employee needs to be adjustable to different cultures, and learn the business values applicable to each of the culture.
A potential leader in a multinational company should be able to overcome the cultural, linguistic and national barriers. Therefore, it is important for the incumbent to be aware of as well as be open to learn other culture.
The various trainings that are apt for international staffing are:
In Plycentric staffing, the senstivity training and cultural awareness training is not required as the incumbent is already acquainted that culture.
However, in ethnocentric staffing, the employee shold be be trained and checked for relevant traits.

Q0)What are the dye moleclecules doing that makes each specta has a different wavelength
Q1) explain how observed color related to absorbed color (hint: color wheel)
Q2) Name at least one vaiable that controls absorbance
Q3) short paragraph answering why green seater apperas black when shining only erd light on it
Q4) ChlorophyII- containing plants appear green. Use color wheel to predit when color of light chlorophyll absorbs?
Solution
0) the molecules of different dyes absorb different wavelengths of visible light. They reflect only one particular color and this is the color of the dye. For example: a molecule of green dye absorbs all colors other than green.
1) the observed color is the color that is not absorbed. All materials absorb some wavelengths and the wavelength that is not absorbed is the observed color.
2) wavelength controls absorbance. Fluctuation in wavelength causes different colors to be absorbed.
3) whatever color we see is a part of white light because white light has all colors. When an object is green, it absorbs all colors except green. When red light shines on it, it absorbs red light and does not reflect anything. Hence it appears black.

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdf
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.
