Java，如何让程序等待视频结束后继续，wait()让程序停止

public class VideoPlayer implements Runnable {
    private Object lock;

    public VideoPlayer(Object lock) {
        this.lock = lock;
    }

    public void run() {
        // 模拟视频播放
        System.out.println("视频播放中...");
        try {
            Thread.sleep(5000); // 假设视频播放需要5秒钟
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("视频播放结束");

        synchronized (lock) {
            lock.notify(); // 唤醒主线程
        }
    }

    public static void main(String[] args) {
        Object lock = new Object();

        // 创建视频播放线程
        Thread videoThread = new Thread(new VideoPlayer(lock));
        videoThread.start();

        synchronized (lock) {
            while (true) {
                try {
                    lock.wait(); // 主线程等待视频结束
                    break; // 视频结束后跳出循环
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }

        // 视频结束后继续执行的代码
        System.out.println("继续执行...");
    }
}
