In the example below, the Student class overrides the getFood() method of the Person() class, and it uses super.getFood() to call the Person getFood() method before adding on to it. Here, a Person is associated with the food "Hamburger" and a Student is associated with "Hamburger" and "Taco".

Add another subclass called Vegan that inherits from the Student class. Add a Vegan contructor that takes a name as an argument and passes it to the super constructor. Override the getFood() method in Vegan to call the superclass getFood() but add a "No " in front of it and then say "but " and add a vegan food. Change Javier to a Vegan object in main() and try it out!

 

public class Person

{

      private String name = null;

 

      public Person(String theName)

      {

         name = theName;

      }

 

      public String getFood()

      {

         return "Hamburger";

      }

 

      public static void main(String[] args)

      {

         Person p = new Student("Javier");

         System.out.println(p.getFood());

      }

   }

 

   class Student extends Person

   {

      private int id;

      private static int nextId = 0;

 

      public Student(String theName)

      {

        super(theName);

        id = nextId;

        nextId++;

      }

 

      public String getFood()

      {

         String output = super.getFood();

         return output + " and Pizza";

      }

 

      public int getId() {return this.id;}

      public void setId (int theId)

      {

         this.id = theId;

      }

   }
