Java中的定时器Timer使用示例代码

import java.util.Timer;  
import java.util.TimerTask;  
public class Reminder ...{  
    Timer timer;  
    public Reminder(int seconds) ...{  
        timer = new Timer();  
        timer.schedule(new RemindTask(),seconds*1000);   //使用Timer类设置定时执行任务，0指过0s开始执行，seconds*1000指每seconds秒执行一次
    }  
    class RemindTask extends TimerTask ...{  
        public void run() ...{  
            System.out.println("Time''s up!");   //要定时执行的任务
            timer.cancel(); //Terminate the timer thread  
        }  
    }  
    public static void main(String args[]) ...{  
        System.out.println("About to schedule task.");  
        new Reminder(5);  
        System.out.println("Task scheduled.");  
    }  
}
