(The Person, Student, Employee, Faculty, and Staff classes) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and email address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. Use the MyDate class defined in Programming Exercise 10.14 to create an object for date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the persons name. Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.

Only add to the program below

import java.util.*;

public class Exercise11_02 { public static void main(String[] args) { } }

class Person { protected String name; protected String address; protected String phoneNumber; protected String email;

@Override public String toString() { return "Person"; } }

class Student extends Person { public static int FRESHMAN = 1; public static int SOPHOMORE = 2; public static int JUNIOR = 3; public static int SENIOR = 4;

protected int status;

@Override public String toString() { return "Student"; } }

class Employee extends Person { protected String office; protected int salary; protected Calendar dateHired;

@Override public String toString() { return "Employee"; } }

class Faculty extends Employee { public static int LECTURER = 1; public static int ASSISTANT_PROFESSOR = 2; public static int ASSOCIATE_PROFESSOR = 3; public static int PROFESSOR = 4;

protected String officeHours; protected int rank;

@Override public String toString() { return "Faculty"; } }

class Staff extends Employee { protected String title;

@Override public String toString() { return "Staff's title is " + title; } }
