calling parent class method from child class object in java

Question

I have a parent class which has a method, in the child class I override that parent class's method. In a third class I make an object of child and by using that object I want call the method of parent class. Is it possible to call that parent class method ? If yes, then how?

Answer 1

If you override a parent method in its child, child objects will always use the overridden version. But; you can use the keyword super to call the parent method, inside the body of the child method.

public class PolyTest{     public static void main(String args[]){         new Child().foo();     }  } class Parent{     public void foo(){         System.out.println("I'm the parent.");     } }  class Child extends Parent{     @Override     public void foo(){         //super.foo();         System.out.println("I'm the child.");     } } 

This would print:

I'm the child.

Uncomment the commented line and it would print:

I'm the parent.

I'm the child.

You should look for the concept of Polymorphism.
