Answer Posted / anjani kumar jha

It is very diffcult for compiler to know which version of
the method called(superclass or subclass).

Hence to identify which version of method is called java
used run-time polymorphism(same copy used in both class)
where object type defined which version is called.
I am giving u one example............

class A
{
public void sum() //this is method which we will override
{
//some operation here//
}
}
class B extends A
{
public void sum() //over-riden method,see both method
r //same
{
//some operation here//
}
public static void main(String as[])
{
A a=new B() //RUN TIME POLYMORFISM
a.sum()//Since a is a object type of class B SO class B sum
method will be called................................
}
}
//I think uy doubt will be clear
}

Thanks and Regards
