In Java Method overriding is the runtime or late binding
polymorphism.

class object is determine which class method is invoked.

ex:

class A {
protected void display(){ }

}

class B extends A {

protected void display(){ }

}

class MainClass {
public static void main(String arg[]){

A objA=null;
objA=new B();
objA.display(); // it invoke the Class B's display()

objA=new A();
objA.display(); // it invoke the Class A's display()

}

}

Note: the class's object only determine which method to call.
