Question

Hi

can do this code Java

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. Define a class named My Date that contains the fields year, month, and day 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. Draw the UML diagram for the classes. Implement the classes. Write a test program that creates a Person, Student, Employee, Faculty', and Staff, and invokes their toString () methods.

Explanation / Answer

Person.java

public class Person {
   //Declaring variables
private String name,address,email_address;
private String phone_number;

//Zero Argument Constructor
public Person() {
   super();
}

//Parameterized constructor.
public Person(String name, String address, String email_address,
       String phone_number) {
   super();
   this.name = name;
   this.address = address;
   this.email_address = email_address;
   this.phone_number = phone_number;
}

//Setters and getters
public String getName() {
   return name;
}
public void setName(String name) {
   this.name = name;
}
public String getAddress() {
   return address;
}
public void setAddress(String address) {
   this.address = address;
}
public String getEmail_address() {
   return email_address;
}
public void setEmail_address(String email_address) {
   this.email_address = email_address;
}
public String getPhone_number() {
   return phone_number;
}
public void setPhone_number(String phone_number) {
   this.phone_number = phone_number;
}

//toString() method displays the contents of the object.
@Override
public String toString() {
   return "Person [name=" + name + ", address=" + address + ", email_address="
           + email_address + ", phone_number=" + phone_number + "]";
}
