In the real world, an entire program is rarely written from scratch. It is very likely that there are classes or functions that already exist. The key to using these existing modules successfully depends on how modular the classes or functions are written.

In this Learning Team assignment, your mission is to take a section of one team member’s Week Four program and replace a similar section of another team member’s Week Four program.

Submit the following deliverables for this Learning Team assignment:

A 700- to 1050-word paper describing the following:

 How the two programs were selected
The process of identifying the classes or functions for replacement
The changes needed to make the final Java™ application program work correctly

The final Java™ application program

Submit your program (java code) along with the screen shots for both positive (by providing valid data as input) and negative testing (by providing invalid data as input) in a MS Word document.

As one of the requirements for the Bachelor of Science in Information Technology program, students must design and develop a computer program using professional principles and standards.

Complete an evaluation of each team member’s Individual program assignment from Week Three using the QC sheet your team developed in Week Two. Consider the following:

Make sure that the source code submitted for evaluation is the same one that is submitted for the individual assignment.

As a team, agree on a deadline for members to have the evaluations completed. This is necessary so the team has time to compile all members’ evaluations. Team members who do not meet the evaluation deadline will not receive full credit for this assignment.

Each Learning Team should organize their input and submit one file only.

Note that using pop-up comments (such as <SHIFT-F2> in Microsoft® Excel) is not acceptable. Team members are encouraged to provide unique comments for each other.  You will not get full credit without detailed comments.

Submit your team’s final QC sheet in the grade book.

http://www.tutorialfirm.com/PRG-420/PRG-420-Week-3-Individual-Assignment-Simple-Commission-Calculation-Program-Part-2

Modify the Week Two Java™ application using Java™ NetBeans™ IDE to meet these additional and changed business requirements:

The company has recently changed its total annual compensation policy to improve sales.

A salesperson will continue to earn a fixed salary of $50,000. The current sales target for every salesperson is  $120,000

The sales incentive will only start when 80% of the sales target is met. The current commission is 5% of total sales.

If a salesperson exceeds the sales target, the commission will increase based on an acceleration factor. The acceleration factor is 1.25

The application should ask the user to enter annual sales, and it should display the total annual compensation.

The application should also display a table of potential total annual compensation that the salesperson could have earned, in $5,000 increments above the salesperson’s annual sales, until it reaches 50% above the salesperson’s annual sales.

Sample Table: Assuming a total annual sales of $100,000, the table would look like this:

Total Sales

Total Compensation

100,000

<<Program calculated value>>

105,000

<<Program calculated value>>

110,000

<<Program calculated value>>

115,000

<<Program calculated value>>

120,000

<<Program calculated value>>

125,000

<<Program calculated value>>

130,000

<<Program calculated value>>

135,000

<<Program calculated value>>

140,000

<<Program calculated value>>

145,000

<<Program calculated value>>

150,000

<<Program calculated value>>

The Java™ application should also meet these technical requirements:

The application should have at least one class, in addition to the application’s controlling class.

The source code must demonstrate the use of conditional and looping structures.

There should be proper documentation in the source code.

Submit your program (java code) along with the screen shots for both positive (by providing valid data as input) and negative testing (by providing invalid data as input) in a MS Word document.

Consider the following conditions:

 CONDITION 1: while ( !(cChoice == ‘Q’ || cChoice == ‘q’) )

CONDITION 2: while ( cChoice != ‘Q’ || cChoice != ‘q’ )

Do Conditions 1 and 2 give the same result? What tool or technique would you use to explain the result?

Select and complete one of the following activities:

Convert the following program from for loop to while loop.

class ArithmeticProgression

{
public static void main (String [] args)
{
int sum = 0;

for (int i = 1; i <= 1000; i++)
{
sum = sum + i;
System.out.println(Integer.toString(sum));
}
}
}

Compare the efficiency between a for loop and a while loop in the same program. Your program should be able to tell if a for loop is faster than a while-loop at the end of the program. Include the result of your run with the information on which one is faster.

Resource: Excel scoring instrument

Create a quality control (QC) sheet based on the scoring instrument. The QC sheet will be used later in this course to evaluate team members’ programs. As a team, share your ideas with each other and create one common QC sheet that your team will use. Your final QC sheet should be compiled in Microsoft® Excel and must include the following:

Areas to enter the evaluator’s name, the name of the program being evaluated, and the date the program is received

A set of detailed criteria for evaluation based on the scoring instrument. List as many criteria as you can that are applicable to evaluate programs.

The values assigned to each component of the evaluation based on the scoring instrument

Areas for detailed evaluation comments. You will not get full credit without detailed comments.

Other elements as appropriate

Submit your team’s final QC sheet in the grade book.

http://www.tutorialfirm.com/PRG-420/PRG-420-Week-2-Individual-Assignment-Simple-Commission-Calculation-Program-Part-1

Write a Java™ application using NetBeans™ Integrated Development Environment (IDE) that calculates the total annual compensation of a salesperson. Consider the following factors:

A salesperson will earn a fixed salary of $50,000

A salesperson will also receive a commission as a sales incentive. Commission is a percentage of the salesperson’s annual sales. The current commission is 5% of total sales.

The total annual compensation is the fixed salary plus the commission earned.

The Java™ application should meet these technical requirements:

The application should have at least one class, in addition to the application’s controlling class (a controlling class is where the main function resides).

There should be proper documentation in the source code.

The application should ask the user to enter annual sales, and it should display the total annual compensation.

Submit your program (java code) along with the screen shots for both positive (by providing valid data as input) and negative testing (by providing invalid data as input) in a MS Word document.

You are a bank manager and you are helping a new bank teller understand the kind of accounts the bank offers. If a customer comes in asking to open a new savings account, the teller needs to ask what kind of account—passbook savings or certificate of deposit—the customer would like to open. Remind the customer that all accounts with our bank are insured by the FDIC. You should explain that all accounts earn some interest; a savings account’s interest is compounded monthly. You should assign a unique account number after accepting the customer’s initial deposit. If the customer chooses to receive statements electronically, the system will send an e-mail with a monthly statement; if the customer chooses not to, then a paper statement will be sent by mail quarterly.

 If savings account is a class, give an example of each of the following as it relates to that savings account. Explain your reasoning behind your example.

 

1   Superclass

2    Subclass

3    Attribute

4    Method

5   Instance (object)

6    Encapsulation
