        MyRunnable m = new MyRunnable();
        Thread t = new Thread(m);

        t.start();

        new Thread(new MyRunnable()).start();
        new Thread(new MyRunnable()).start();
    }
    static class MyRunnable implements Runnable{
    
    

        @Override
        public void run() {
