Default Dynamic Binding
I have two classes, Super and Sub

class Super{
int a=100
}

class Sub extends super{
int a=500;
}

class Test{
Super sup = new Sub();
S.o.p(sup.a)
}

The Output Is 100. Why In Case Of Variable JVM Does not find The SubClass One?

How did you get that output. There should be a filed hiding. You use the same filed name on Sub and Super classes and use the same variable name. If you are working on a Java IDE you should notice it.

So, since you use the sup object reference with the Super class you definitely get the result is 100. It never refer the variable a of the class Sub.

Hope it's clear to you.
