JAVA定时器简单实例

package timer;

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 * 1000,3000);//seconds * 1000 任务前延时    3000间隔     }

    class RemindTask extends TimerTask {

        @Override         public void run() {             System.out.println("Time's up!");             //timer.cancel();//Terminate the timer thread         }     }

    public static void main(String[] args) {         System.out.println("About to schedule task.");         new Reminder(10);         System.out.println("Task scheduled.");     } }
