just look at the code in above

do you see ?
Base b = new Subclass();

it is asking , value of b.x and b.method()

I am very surprised , b has taken the x value from class Base and
method() from Subclass .

why ?

it should take both the value from Subclass .....why ? well, because
the real object is a Subclass object and b is a just a reference
.......so b should pull out BOTH the values from the Subclass object.

why it picked up ONE value from Base class and OTHER value from
Subclass ?

Hi!
Methods are bound dynamically, variables are not. That's why.
