java中的定时器Timer

package com.tonglian.test;

import java.util.TimerTask;

//TimerTask是个虚类，其中有一个run()

public class Work extends TimerTask{

@Override
public void run() {
// TODO Auto-generated method stub
System.out.println("tttt/n");
}

}

//功能：每隔1秒就会调用Work中的run()方法

package com.tonglian.test;

import java.util.Timer;

public class Test {
public static void main(String[] args) {
Timer timer=new Timer();
timer.schedule(new Work(), 0,1000);
}
}
