Question

in java

Design and implement 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 (year 1,year 2,year 3,or year 4). An employee has an office, salary, and date hired. Use the Date class from JavaAPI 8 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 person’s name.Design and implement all 5classes. Write a test program that creates a Person,Student,Employee,Faculty, and Staff, and iinvokes their toString()methods

Answer 1

Answer:

Driver class has all the objects from the mentioned classes, all you need is to execute this class.

import java.time.LocalDate;

public class TestManyClasses {
public static void main(String[] args){
// Person object
Person person = new Person();
person.setName("Adams");
person.setAddress("Eire Island");
person.setEmailId("[email protected]");
person.setPhoneNumber("9809999999");
System.out.println("The person object: \n" + person);

// student object
Student student = new Student();
student.setName("Adams Paul");
student.setAddress("University Of Texas");
student.setEmailId("[email protected]");
student.setPhoneNumber("9809999999");
student.setClass(Student.Status.year_1);
System.out.println("Student object : \n" + student);

// employee object
Employee employee = new Employee();
employee.setName("Christina Kerr");
employee.setAddress("St Peter's Street, California");
employee.setOffice("Google Inc");
employee.setSalary(100000);
employee.setEmailId("[email protected]");
employee.setPhoneNumber("9991919191");
employee.setDateHired(LocalDate.of(2010, 2, 14));
System.out.println("The employee object : \n" + employee);

// The faculty object
Faculty faculty = new Faculty();
faculty.setName("Albert");
faculty.setOfficeHours(10);
faculty.setOffice("Dallas");
faculty.setRank(1);
faculty.setDateHired(LocalDate.of(2009, 5, 10));
faculty.setAddress("Peters Burg");
faculty.setPhoneNumber("9080898984");
faculty.setSalary(1006033);
System.out.println("The faculty object: \n" +faculty);

// The staff object
Staff staff = new Staff();
staff.setName("Christopher");
staff.setTitle("Asst Prof");
staff.setAddress("Washington DC");
staff.setDateHired(LocalDate.of(2012, 5, 19));
staff.setEmailId("[email protected]");
staff.setOffice("Main branch");
staff.setPhoneNumber("9898925923");
staff.setSalary(15000);
System.out.println("The staff object : \n" + staff);
}
}
