通过Calendar简单设置定时器启动时间

 public static void main(String[] args) {
        Calendar cc = Calendar.getInstance();
        cc.set(2010,8-1,3,13,7,0);
        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
         private int i = 1;
         public void run() {
          System.out.println("----------------" + i++); 
         }
        },cc.getTime(), 2000);
 }
