Method Overriding in Java

           When a method in a sub class has the same name and type as a method in its super class,then the method in the subclass is said to be override in the super class.When an overridden method is called from within a subclass,then it will always refer to the version of that methoddefined by the subclass.The version of the method defined by the super class will be hidden.
     class A
     {
               void show( )
               {
                       System.out.println( "\nsuper class !");
               }
     }
     class B extends A
     {
               void show( )
               {
                       System.out.println( "base class!" );
               }
     }
     class Overriding( )
     {
               public static void main(String args[ ] )
               {
                      B obj = new B( );
                      obj.show( );
                      super.show( );
               }
     }
OUTPUT
  base class!
  super class
     here the versions of show( ) inside B overrides version declared in A.To access the super class version of overridden function it can do so by using super keyword.In the programe it is illustrated as
   super.show( );
and it will call the super class function.
