Answer to Question #197437 in Java | JSP | JSF for Syed kaif ali

Question

Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee.

(The Person, Student, Employee, Faculty, and Staff classes)

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. 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 a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.

Answer 1

public class PersonDemo {
	public static void main(String args[]) {
		Person person = new Person("Daniel Dyson"), student = new Student("Charles Evans"),
				employee = new Employee("Ethan Carter"), faculty = new Faculty("Harold Brooks"),
				staff = new Staff("Connor Stevenson"), people[] = { person, student, employee, faculty, staff };
		for (Person p : people)
			System.out.println(p);
	}




static class Person {
	String name, address, phoneNumber, email;


	Person(String n) {
		name = n;
	}


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


static class Student extends Person {
	Student(String n) {
		super(n);
	}


	enum Status {
		freshman, sophomore, junior, senior
	}


	Status classStatus;


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


}


static class Employee extends Person {
	Employee(String n) {
		super(n);
	}


	String office, hireDate;
	double salary;


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


static class Faculty extends Employee {
	Faculty(String n) {
		super(n);
	}


	String officeHours, rank;


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


static class Staff extends Employee {
	Staff(String n) {
		super(n);
	}


	String title;


	@Override
	public String toString() {
		return "Staff " + name;
	}
}}
