如何在Java中暂停/恢复和停止我的计时器？

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

public class TimerExample {
    private static Timer timer;
    private static TimerTask task;
    private static long delay = 1000; // 延迟1秒
    private static long period = 1000; // 每隔1秒执行一次

    public static void main(String[] args) {
        timer = new Timer();
        task = new TimerTask() {
            @Override
            public void run() {
                // 定时任务的逻辑代码
                System.out.println("Timer task is running...");
            }
        };

        // 启动计时器
        startTimer();

        try {
            Thread.sleep(5000); // 暂停5秒
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        // 暂停计时器
        pauseTimer();

        try {
            Thread.sleep(5000); // 暂停5秒
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        // 恢复计时器
        resumeTimer();

        try {
            Thread.sleep(5000); // 暂停5秒
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        // 停止计时器
        stopTimer();
    }

    private static void startTimer() {
        timer.schedule(task, delay, period);
        System.out.println("Timer started.");
    }

    private static void pauseTimer() {
        task.cancel();
        System.out.println("Timer paused.");
    }

    private static void resumeTimer() {
        task = new TimerTask() {
            @Override
            public void run() {
                // 定时任务的逻辑代码
                System.out.println("Timer task is running...");
            }
        };
        timer.schedule(task, delay, period);
        System.out.println("Timer resumed.");
    }

    private static void stopTimer() {
        timer.cancel();
        System.out.println("Timer stopped.");
    }
}
