Java Inheritance:

Build a new Employee class(Employee.java). This class will be a sub-class of Person. So it will inherit all the properties of Person(FirstName, LastName, Address and Email). Also add 2 new properties, an employee id number and a salary. Create this class, make sure to add 2 constructors(one that takes no args and 1 that takes all props from both the Person class and the Employee class) and a display() method that prints out all the props from both the Person class and the Employee class. Then use main to test out this class.

Main code:

Employee e1;

e1 = new Employee(2323, Bill, Clinton, Marietta, bc@msn.com, 43000.00);

e1.display(); //prints all 6 properties

Here is what I got so far:

public class Person {

// ========================== Properties ===========================

private String FirstName;

private String LastName;

private String Address;

private String Email;

//constructor with parameters

Person(String FirstName,String LastName,String 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 = "";

this.Email = "";

}

// ========================== Behaviors ==========================

public void setFirstName(String fn) {

this.FirstName = fn;

}

public void setLastName(String ln) {

this.LastName = ln;

}

public void setAddress(String a) {

this.Address = a;

}

public void setEmail(String e) {

this.Email = e;

}

public String getFirstName() {

return this.FirstName;

}

public String getLastName() {

return this.LastName;

}

public String getAddress() {

return this.Address;

}

public String getEmail() {

return this.Email;

}

//method that displays person data

public void display() {

System.out.println("First Name : "+this.FirstName);

System.out.println("Last Name : "+this.LastName);

System.out.println("Address : "+this.Address);

System.out.println("Email : "+this.Email);

} //end display()

//overriding toString method

public String toString() {

return "FirstName: "+getFirstName() + " LastName: "+getLastName() + " " +this.Address.toString()

+" Email: "+getEmail();

}

//main method

public static void main(String args []) {

Person p1;

p1 = new Person("Rodney","Duncan","70 Bowman St. South Windsor, CT 06074","rduncan@msn.com");

p1.display();

}

}
