PRG 420 Version 10 (v2) Week 1 Individual Assignment Create a Program Create a program in Java™ that displays “Hello world!” Take a screen shot that shows the program’s successful compilation and execution. Then submit your program along with the screen shot. Note. No points will be awarded for submitting the program alone. Discussion Questions DQ 1 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? 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 PRG 420 Version 10 Week 2 (v2) 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 $55000 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 15% 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. Discussion Questions
DQ 1 A class is a blueprint for an object. A class may have a default constructor, a constructor with arguments, accessor methods, mutator methods, public fields, and private fields. Choose a category (such as animal, vehicle, and so on) and describe how you would design a class for it. DQ 2 List three types of errors you may encounter in a Java program. Describe what to do to minimize errors.
PRG 420 Ver. 10 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 $55000. The current sales target for every salesperson is $500,000
•
The sales incentive will only start when 80% of the sales target is met. The current commission is 15% of total sales.
•
If a salesperson exceeds the sales target, the commission will increase based on an acceleration factor. The acceleration factor is 1.50%
•
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 $5000 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>>
150,000
<<Program calculated value>>
200,000
<<Program calculated value>>
250,000

<<Program calculated value>>
500,000
<<Program calculated value>>
..... 950,000
...
1,000,000
<<Program calculated value>> <<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. Discussion Questions DQ 1Our focus this week is loops. 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)); 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? PRG 420 Version 10 Week 4 (v2) Individual Assignment Write a simple commission calculation program using IDE. Modify the Week Three Java™ application using Java™ NetBeans™ IDE to meet these additional and changed business requirements: •
The application will now compare the total annual compensation of at least two salespersons.
•
It will calculate the additional amount of sales that each salesperson must achieve to match or exceed the higher of the two earners.
• • •
The application should ask for the name of each salesperson being compared.
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 Array or ArrayList. There should be proper documentation in the source code. Discussion Questions DQ 1 What is the difference between arrays and ArrayList? What are the advantages and disadvantages of an ArrayList, and when should you use an ArrayList over a simple array? DQ 2 What is the difference between string and StringBuilder? What are the advantages and disadvantages of a StringBuilder, and when should you use a StringBuilder over a simple String? WEEK 5 Discussion Questions DQ 1 In your opinion, what are the three biggest challenges in planning and designing a solution for a programming problem? What can you do to overcome these challenges? How would you apply these techniques to the programs in this class?
DQ 2 Using an example from your work or daily life, describe an “is-a” relationship. Why is an “is-a” relationship important when designing an inheritance between classes?
