我已经尝试了在这里和论坛上都能找到的所有解决方案，但是无论我做什么，我都无法关闭JFrame，我也不知道为什么。我需要处理JFrame并通过创建WarioWareGUI对象来启动另一个JFrame。
现在，我似乎能做的最好的事情就是阻止球移动，只将旧的JFrame留在后台，但这还不够好。我需要风JFrame关闭
我尝试了无限处理，我尝试将JFrame设置为公共静态并将其初始化为BallGame的对象，以便可以在任何地方进行处理。我尝试过在创建后立即将其丢弃。似乎没有什么可以摆脱它的。
我什至尝试将球速设置为0，并使帧不可见，但为wind.setVisible（false）;。也不做任何事情。

我希望调用wind.dispose来关闭GUI，但是无论我放在哪里或如何声明JFrame，它都不会关闭。我也不能使它不可见。
现在的代码就是我放弃时的代码，我当然不打算立即处置它，但是一旦我能成功处置它，就可以将它付诸实践。在正确的时间做到这一点。
