(The Person, Student, Employee, Faculty, and Staff classes) Design a class named

Question

(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, and address. A student has a class status(freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, and salary. A faculty member has office hours. A staff member has a title.

Override the toString method in each class to display the class name and available information of the person.

Explanation / Answer

package demo;

import java.util.ArrayList;
import java.util.List;



abstract class Person {
String name;
String address;


@Override
public String toString() {
// TODO Auto-generated method stub
return this.getClass().getName();
}
}
class Employee extends Person{
String office;
String salary;
@Override
public String toString() {
// TODO Auto-generated method stub
return this.getClass().getName();
}
public Employee(String a)
{
System.out.println(a);
}

}
class Student extends Person{

@Override
public String toString() {
// TODO Auto-generated method stub
return this.getClass().getName();
}
public Student(String b)
{
System.out.println(b);
}
}

class Faculty extends Employee{
public Faculty(String a) {
super(a);
// TODO Auto-generated constructor stub
}
int officeHours;
@Override
public String toString() {
// TODO Auto-generated method stub
return this.getClass().getName();
}
}
class Staff extends Employee{
public Staff(String a) {
super(a);
// TODO Auto-generated constructor stub
}
int officelittle;
@Override
public String toString() {
// TODO Auto-generated method stub
return this.getClass().getName();
}
}

public class Test
{
public static void main(String[] args)
{
Person s1=new Student("s1 is initialized");
Person s2=new Student("s2 is intialized");

Employee faculty=new Faculty("faculty instantiated");
Employee staff=new Staff("Staff instantiated");


List<Object> all=new ArrayList<Object>();

all.add(s1);
all.add(s2);
all.add(faculty);
all.add(staff);

for (int i = 0; i < all.size(); i++) {
System.out.println(all.get(i));
}

}
}
