线程之Timer

2秒后执行TimerTask, 然后每隔一秒执行一次

package com.lyj;import java.util.Timer;import java.util.TimerTask;public class TraditionalTimerDemo {    public static void main(String[] args) {        Timer timer = new Timer();        timer.schedule(new TimerTask() {                        @Override            public void run() {                System.out.println("lyj");            }        }, 2000, 1000);    }    }
