Description
Objectives:
Practice implementing classes
Practice creating and using objects
Practicing using classes
Practice creating tester programs
Assignment:
For this assignment, you are going to simulate a company roster. You will need 3 separate files:
one for the Employee class, one for the EmployeeTester class, and one for the Company class.
Employee Class
This class will simulate employees.
You will need 4 instance variables for:
Employee’s name
Employee’s ID number
Department employee works in
Employee’s position in the company
You will need a getter and setter to access each of the instance variables (8 methods total).
You will need to include an argument constructor and a no-argument constructor to initialize the
instance variables.
EmployeeTester Class
This class will test the methods and constructors of the Employee Class.
Create 2 objects, one with the argument constructor and one with the no-argument constructor.
2
On the object constructed with the argument constructor, call all the getter methods to make sure
the instance variables were initialized correctly.
On the object constructed with the no-argument constructor, call all the setter methods and set
the instance variables to the values of your choosing. Then, call all the getter methods to make
sure the setters worked correctly.
The output that should be produced by this class is shown below in the sample execution section.
Company Class
This class will use the Employee class to simulate 3 employees. Below is the employee
information you will use:
Name ID Number Department Position
Susan Meyers 47899 Accounting Vice President
Mark Jones 39119 IT Programmer
Joy Rogers 81774 Manufacturing Engineer
Create 2 objects of the Employee class using the argument constructor and 1 object with the noargument constructor. Set the values of the instance variables to the information in the table.
Using the getter methods, display each employee’s information in a table, shown below.
The output that should be produced by this class is shown below in the sample execution section.
