Java Timer与TimerTask类使程序计时执行

import java.util.Timer;
import java.util.TimerTask;

class Test extends TimerTask{
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName()+"时间："+System.currentTimeMillis());
    }
}
public class Hello {
    public static void main(String[] args) {
        Timer timer = new Timer();
        timer.scheduleAtFixedRate(new Test(),100,1000);
    }
}

timer.scheduleAtFixedRate(new Test(),100,1000);
