class A extends Thread {
public A(Runnable r) {super(r);
run();
}
public void run() {System.out.print("A");}
}

class B implements Runnable {
public B()
{
run();
}
public void run() {System.out.print("B");}

}

class Cero {
public static void main(String[] args) {
new A(new B()).start();
}
}// why it is printing BAA
// first call should go to super class only

[vidya sagar]

tell why it is priting A only suppose to print BA Know??

Because the statement new A(new B()).start(); (see brackets carefully) is tends to calling start method on class A.

[Lalitha Gottumukkula]

Because you have started only one thread
i.e.,
new A(new B()).start(); will start only thread A.

[Vishnu Prakash]

You are calling the start method(which is used to spawn a new thread) only on the instance of class A and not on class B. So the result will be only A.
