Question 6

What is the output of following program:

public class Test {

public static void main(String[] args) {

B b = new B(2);

b.methodAB();

}

}

class A {

public A() {

System.out.println("A's constructor is executed");

}

public void methodA() {

System.out.println("methodA is executed");

}

public void methodAB() {

System.out.println("A's methodAB is executed");

}

}

class B extends A {

private int num = 0;

public B() {

super();

System.out.println("B's constructor is executed");

}

public B (int n)

{

num = n;

System.out.println("B's constructor is executed");

}

public void methodB() {

System.out.println(num is + num);

System.out.println("methodB is executed");

}

public void methodAB() {

System.out.println("B's methodAB is executed");

}

}

	A.	B's constructor is executed B's methodAB is executed
	B.	Compiling time error because both classes A & B have methodAB.
	C.	B's constructor is executed A's methodAB is executed
	D.	A's constructor is executed B's constructor is executed B's methodAB is executed
