Java™ is a portable language, and being an object-oriented programming language, it also
encourages component reusability. How does Java™ achieve these two important features?
How are these features desirable in modern software engineering?

PRG 420 Week 1 DQ 2
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.

o Subclass

What are the three types of errors that you can encounter in a Java program? Describe
them, and explain how you would minimize the errors. What are some examples of errors
that you have seen before?

PRG 420 Week 2 DQ 2
Give an example or counterexample that demonstrates each of the following criterion. Why
is each criterion important to a program?
· Is indentation used correctly to illustrate the structure of the program?
· Is there a consistent naming convention?
· Do comments explain processing that is not obvious?

http://www.uopassignments.com/PRG-420/PRG-420-Week-2-Individual-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.

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.

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.

PRG 420 Week 3 DQ 2
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?

http://www.uopassignments.com/PRG-420/PRG-420-Week-3-Individual-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

Complete an evaluation of each team member’s individual program assignment 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.

Reusability
http://www.uopassignments.com/PRG-420/PRG-420-Week-5-Learning-Team-Reusability-
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:
o How the two programs were selected
o The process of identifying the classes or functions for replacement
o The changes needed to make the final Java™ application program work correctly
• The final Java™ application program
