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.");
