Java 计时器的实现

代码如下：

import static com.hutao.util.Print.*;
import java.util.Timer;
import java.util.TimerTask;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		long time = System.currentTimeMillis();
		TimerTask task = new TimerTask() {
			@Override
			public void run() {
				String str = String.format("%1$tM:%1$tS:%1$1tL", System.currentTimeMillis() - time);
				println(str.substring(0, 7));
			}
		};
		new Timer().schedule(task, 1, 100);

	}
	
}
