Assignment Description

This assignment focuses on programming basics; expressions, variables, constants, static methods and loops.

David runs a Pizza shop in the inner suburbs of Melbourne. Due to the growing number of customers, Pizza shop has decided to take on extra casual employees. In order to manage payroll for his employees, David has decided to develop an employee payroll management system. Details of each employee to be maintained in the system will include; 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%.

For example, an employee who has worked a total of 35 hours with an hourly rate of $20 will have;

Gross pay=35*$20=$700

Income tax payable=$700 * 30%=$210

Net pay=$700-$210=$490

Task Requirements

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 MITnnnnnEmployeewhere 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.

David’s Pizza Parlour ABN: 111 222 333

Employee: Joe Smith

Payment Date: 10/09/2018

Gross Pay: $700.00

Net Pay: $490.00

Pay Period from: 01/09/2018 to 08/09/2018

Item Total Hours Calculated Rate Type

Base Hourly @$20.00 35 $700.00 Wages

PAYG Withholding $-210 Tax

Submission requirements:

  1. Your assignment should include the following in the .ZIP archive:

· A Word report containing aUML 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)

  1. 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

Marking criteria:

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.

Marking Rubric for Assignment #:Total Marks 20











Excellent Very Good Good Satisfactory Unsatisfactory
UML class design


All variables and their data types together with the associated methods are identified and represented in UML diagram UML class diagram is generally well annotated UML class diagram is fairly annotated with some information missing UML class diagram is annotated but most of the information is missing No diagram or diagram provided is not relevant to the assignment topic.
Java implementation


UML design is excellently implemented and the code is well documented. The program runs and outputs the correct results UML design is well implemented with a few minor issues UML design is implemented but there some issues with the implementation UML design is implemented but there are a number of issues Implementation does not satisfy problem specification
