    public MyRunnable()
    {

        t = new Thread(this);
        System.out.println("Executing " + t.getName());
        // this will call run() fucntion
        t.start();

        /*
         * Tests whether the current thread has been
         * interrupted.
         */
        if (!t.interrupted())
        {
            // Interrupts this thread.
            t.interrupt();
        }
        // block until other threads finish
        try
        {
