class Test
{
    public static void main(String [ ] args)
    {
        Base b = new Subclass();
        System.out.println(b.x); // this access from Base
        System.out.println(b.method());// this access from Subclass
    }
}

class Base
{
    int x = 2;
    int method()
    {
        return x;
    }
}

class Subclass extends Base
{
    int x = 3;
    int method()
    {
        return x;
    }
}

output:
----------

2
3

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 ?
