如何在java中制作倒计时countdown定时器(秒表Java )

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

public class CountdownTimer {
    public static void main(String[] args) {
        int seconds = 10; // 设置倒计时的秒数

        Timer timer = new Timer();
        TimerTask task = new TimerTask() {
            int remainingSeconds = seconds;

            @Override
            public void run() {
                if (remainingSeconds > 0) {
                    System.out.println("倒计时：" + remainingSeconds + "秒");
                    remainingSeconds--;
                } else {
                    System.out.println("倒计时结束");
                    timer.cancel();
                }
            }
        };

        timer.scheduleAtFixedRate(task, 0, 1000); // 每隔1秒执行一次任务
    }
}
