Question

This is heavily based on Programming Exercise 11.2 in the Liang text. However, you will not need the text version to do this assignment, many changes have been made.

The archive assign02.zip is attached has a skeleton project for this assignment. All the test programs are there that will be used to test your work. The different classes you are to implement are present in skeleton form.

Requirements

Implement classes Person, Student, Employee, Faculty and Staff. These represent the people and categories of people you might find at a college or university. These are related by inheritance as follows

Employee and Student both extend Person

Faculty and Staff both extend Employee

Here are the instance fields of each class:

Class

Instance Fields

Person

name
email address

Employee

salary
date hiredB

Faculty

office hours

Staff

title

Student

class statusA

Here are the notes from the table:

This should be a string. The most common values will be one of “FR”, “SO”, “JR”, “SE”, but don’t bother testing for that.

Use the standard Java Date class

Instance field types should be String except for salary and date hired.

The classes will have the following methods:

Getters and setters for all instance fields, except

Date hired has no setter

A single constructor in each class that initializes all the fields for that class both inherited and defined in the class itself, except for date hired For example, he Staff constructor will have 4 parameters: title, salary, name, and email address

The constructor for Employee will initialize the hire date to the current date

Override toString in each class to print the name of the class followed by the name of the person, separated by a colon. For example, if Bob is a staff member, his object would print as Staff:Bob.

format each program start like this for each role student-etc.

import java.util.Date;

public class Employee {


  
}

Class

Person
