所以我想弄清楚如何创建一个计时器,我遇到了这个: 使用ScheduledExecutorService来启动和停止计时器

他们的例子看起来效果很好.我只是想知道我是否正确使用它:

  public class TimerTest 
{
  private ScheduledExecutorService  es = null;
  private  boolean timeIsUp = false;
  private ScheduledFuture futureHandler = null;
  private  TimeKeeper timeKeeper = null;
  private  String subject = "";
  private  int siteNo;
  private  long time; 
  private  boolean stop;




public  void endTimer()
{
    System.out.println("we should shutdown everything here");
    es.shutdownNow();
}

public  boolean stopTimer()
{

    if (timeKeeper != null)
    {
        timeKeeper.deactivate();
    }
    futureHandler.cancel(true);
 return true;

}
public  boolean isTimeup()
{
    return timeKeeper.isTimeUp();
}
public void startTimer(long mseconds, String subj, …
