Inheritance:

Build a new Student class("Student.java"). This class will be a subclass of Person. So it will inherit all the properties of Person(FirstName, LastName, Address, and Email).Also, add 3 new properties: studentId, major, and GPA. A total of 7 properties. Create this class, make sure to add 2 constructors, all set and get methods, a display() method, and a toString method. Then use main to test out this class.

Main code:

Student s1;

s1 = new Student(900077661, "Bill", "Clinton", new Address ("123 Main", "Atlanta", "GA", 30111), "HYPERLINK "mailto:bc@msn.com" bc@msn.com", "CS", 3.5);

s1.display();//print all 7 properties.

Here is what I got so far:

import java.util.*; import java.lang.*; import java.io.*; class Person { //class properties private String firstName; private String lastName; private Address address; private String email;

//constructor with parameters Person(String firstName,String lastName,Address address,String email) { this.firstName = firstName; this.lastName = lastName; this.address = address; this.email = email; }

//constructor with no parameters Person() { this.firstName = ""; this.lastName = ""; this.address = new Address(); this.email = ""; }

//set methods //method that sets firstname public void setFirstName(String firstName) { this.firstName = firstName; }

//method that sets lastname public void setLastName(String LastName) { this.lastName = lastName; } //method that sets address public void setAddress(Address address) { this.address = address; }

//method that sets email public void setEmail(String email) { this.email = email; }

//get methods //method that returns firstname public String getFirstName() { return this.firstName; } //method that returns lastname public String getLastName() { return this.lastName; } //method that returns address public Address getAddress() { return this.address; }

//method that returns email public String getEmail() { return this.email; }

//method that displays person data void display() { //print the person details System.out.println("FIRST NAME : "+this.firstName); System.out.println("LAST NAME : "+this.lastName); this.address.display(); //in order to print the address use the display method of Address class System.out.println("EMAIL :"+this.email); }

//overridding toString method public String toString() { return "First name : "+getFirstName() + " Last name : "+getLastName() + " " +this.address.toString() +" Email :"+getEmail(); } //main method public static void main (String[] args) throws java.lang.Exception { Person p1; p1 = new Person("James", "Jones", new Address ("123 Main St.","Dallas","TX",56565), "jj@yahoo.com"); p1.display(); } }
