           public void run() {

              String cur_Time = new SimpleDateFormat("HH:mm:ss").format(new Date());

              System.out.println(cur_Time);

              if(cur_Time.equals("12:00:00")){

                  timer.cancel();//停止定时器

              }

           }

       },0,1000);//定时器执行间隔时间，单位毫秒

    }

}
