This assignment focuses on programming basics; expressions, variables, constants, static methods and loops.
Danny runs an ice cream shop in the inner suburbs of Melbourne. Due to the growing number of customers, Danny has decided to take on extra casual employees. In order to manage payroll for his employees, Danny has decided to develop an employee payroll management system. Details of each employee to be maintained in the system will include; employee id, name, gender (M or F), phone number, hours worked, pay per hour, gross pay, net pay, and income tax payable.
The gross pay is calculated as the number of hours worked multiplied by pay per hour, while the net pay is calculated as the difference between gross pay and income tax payable of which income tax payable is calculated by multiplying gross pay by an income tax rate of 30%. Any hours over forty (40) is paid as an overtime hour at the rate of (2.5) times the base hourly rate.
For example, an employee who has worked a total of 45 hours with an hourly rate of $20 will have;
Overtime pay=5 * $20 * 2.5 = $250
Gross pay=$800 + $250 = $1,050
Income tax payable=$1050 * 30%=$315
Imagine you have been hired to develop this system. Familiarise yourself with the problem description and complete the following tasks:
1. Develop a UML class diagram based on the problem description. The name of the class should be of the form MITnnnnnEmployee where MITnnnnn is your MIT ID.
a. Identify a constructor for the class
b. Identify all the attributes for the Employee class
c. Identify all the set and get methods for each of the attributes identified in 1.b
2. Write a Java implementation of the UML diagram defined in 1. In your class, include comments describing the function of the class, the name of the programmer and the date of implementation.
3. Write a Java program named EmployeePayroll with a main method. Within the main method, you will create(instantiate) an object of your implementation class in 2, and other create methods for calculating wages for the employees. Include comments for all the implemented methods.
a. Declare all variables required for calculations as class variables.
b. Include static methods to calculate the gross pay, income tax payable and the net pay.
c. Once you have calculated the gross pay, income tax payable and net pay. Invoke the methods in correct order so that when your program executes, it should be able to produce an output as an employee’s pay slip like the example below.

1. Your assignment should include the following in the .ZIP archive:
• A Word report containing a UML class diagram based on the problem description of the assignment
• Java source code file for the class (.java file)
• Compiled file for the class (.class file)
2. Instructions for archiving and submitting your files:
• Create a folder and name it with your student ID (MITnnnnnn, where nnnnnn are digits of your student number)
• Copy your Word document, .java and .class files into that folder. • Zip the folder.
i. Right-click on the folder
ii. In the pop-up menu select Send-to, Compressed (zipped)Folder • Then submit this zipped folder in Moodle submission link
Program Demonstration: Students must demonstrate their program in week8 (lab time) to the tutor, and are expected to explain their implementation. Marks will be deducted (50% -maximum) for failing to do demonstration or poor explanation.
