Question

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 e-mail 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. 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 person’s name.

Write a test program that creates objects of Person, Student, Employee, Faculty, and Staff, and invoke their toString() methods.                  

Answer 1

class Person
{
   String name;
   String address;
   String phonenumber;
   String email;
   Person(String name, String address, String phonenumber, String email)
   {
       this.name = name;

       this.email = email;
   }
   public String toString()
   {
       System.out.println("class name: Person");
       System.out.println("Details");
       return "name:\t"+this.name+"\naddress:\t"+this.address+"\nphone number:\t"+this.phonenumber+"\nemail:\t"+this.email;
   }
}
class Student extends Person
{
   final String status;
   Student(String name, String address, String phonenumber, String email, String status)
   {
       super(name, address, phonenumber, email);
       this.status = status;
   }
   public String toString()

   public static void main(String args[])
   {
       Person person1 = new Person("person1", "address1","5566777544","person1email");
       System.out.println(person1.toString());
       Person student1 = new Student("student1", "address2","55667897544","student1@gm.com", "junior");

       Person employee1 = new Employee("employee1", "address3","5578667544","employee1email", "banglore", 100000,"01-08-1019");
       System.out.println(employee1.toString());
       Person faculty1 = new Faculty("faculty1", "address4","6977987544","faculty1email", "banglore", 500000, "01-06-2018", 5, 3);
       System.out.println(faculty1.toString());
