abstract class A

{
    void display()
    {
    }
}

class B extends A

{
    void display()
    {
        super.display();

        -----------------
    }
    public static void main(String args[])

    {
        B b1=new B();

        b1.display();
    }
}

all three answers above are correct. in 3rd one we are assigning object of B to reference of B itself. But in first and second answers we are assigning object of B to Reference of A. In all three cases JVM will invoke B's display() only.
