关于CountDown Timer Java、Android的问题

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

public class CountDownTimerExample {
    public static void main(String[] args) {
        int seconds = 10; // 倒计时时间（以秒为单位）

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

            @Override
            public void run() {
                if (remainingSeconds > 0) {
                    System.out.println(remainingSeconds);
                    remainingSeconds--;
                } else {
                    System.out.println("倒计时结束");
                    timer.cancel(); // 取消计时器
                }
            }
        };

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

import android.os.CountDownTimer;

public class CountDownTimerExample {
    public static void main(String[] args) {
        int seconds = 10; // 倒计时时间（以秒为单位）

        CountDownTimer timer = new CountDownTimer(seconds * 1000, 1000) {
            @Override
            public void onTick(long millisUntilFinished) {
                int remainingSeconds = (int) (millisUntilFinished / 1000);
                System.out.println(remainingSeconds);
            }

            @Override
            public void onFinish() {
                System.out.println("倒计时结束");
            }
        };

        timer.start();
    }
}
