java如何使用TimerTask编写一个定时任务调度器呢?

  定时任务调度器的编写方法:
      1.编写一个TimerTask实例
	  2.定义Timer控件
	  3.借助timer.schedule方法启动任务

package com.java265;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;
 
public class TimerTaskTest {
    public static void main(String[] args) {
        TimerTask timerTask = new TimerTask() {
            @Override
            public void run() {
                while (true) {
                    try {
                        Thread.sleep(2000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    System.out.println("TimerTask当前之间为：" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
                }
            }
        };

        Timer timer = new Timer();
        long delay = 0;
        long period = 1000;
        timer.schedule(timerTask, delay, period);
    }
}
