Why is the output different in the two cases?

Question

Why is the output different in the below case even when, the variable has been overridden?

public class A {
    int a = 500;

    void get() {
        System.out

There is no such thing as overridden variables. B actually has two instance variables named a: one it declares and another it inherits. See this:

B ob = new B();
System.out.println("B.a is " + ob.a);
System.out.println("A.a is " + ((A)ob).a);

Inside a B's instance method you can write super.a or ((A)this).a to access the parent's variable.
