MyThread mt = new MyThread();
Thread t1 = new Thread(mt);
Thread t2 = new Thread(mt);
t1.start();
t2.start();

The threads t1 and t2 execute asynchronously and possibly prints ABCA or AAGB.
You have been asked to modify the code to make the threads execute synchronously and prints ABC.

Which modification meets the requirement?
