Answer 1

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;

public class Clock {

public static void main(String[] args) throws Exception{
time();
}

private static void time() throws Exception{
final SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
//定时任务
TimerTask task = new TimerTask() {
@Override
public void run() {
System.out.println("当前时间："+format.format(new Date()));
}
};
//创建定时器
Timer timer = new Timer();
//开始时间
long delay = 0;
//延迟时间
long intevalPeriod = 1 * 1000;
//开始执行定时任务
timer.scheduleAtFixedRate(task, delay, intevalPeriod);
}
}
