Question

在我的应用中，我已经为我的JFrame家添加了一些音乐。现在，当我在我的主电源上运行时，没有问题他打开Home JFrame，同时播放音乐。

import Muziek.Sound;
import View.Home;

public class Main {


    public static void main(String[] args) {
    Home home = new Home(); 
    home.setVisible(true);

    }
}

但是现在当我运行我的Home课程时，JFrame在音乐播放时变为白色，当音乐停止时我可以看到我的JFrame。现在我已经阅读了一些关于线程的内容，所以你可以在同一时间运行它，但我现在不知道如何做到这一点。

之前我没有使用Clip，但是你应该在一个单独的线程上播放音乐，因为你不应该在UI线程上执行长时间运行的任务（它会冻结UI，你可以看到）：

public void run() 
{

    prepare();
    clip.start();
    // ...
}

public void play(){
    new Thread(this).start();
}

使用我的JFrame同时播放音乐
