    public AnnoyingBeep（） {
        toolkit = Toolkit.getDefaultToolkit（）;
        timer = new Timer（）;
        timer.schedule（new RemindTask（） 0 1*1000）; 
        //timer.scheduleAtFixedRate（new RemindTask（） 0 1*1000）; 
    }

    class RemindTask extends TimerTask {
        int numWarningBeeps = 3;
 
        public void run（） {
            if （numWarningBeeps > 0） {
                toolkit.beep（）;
                System.out.println（“Beep!“）;
                numWarningBeeps--;
            } else {
