我已经创建了一个 GUIPanel，但是我需要将它添加到我拥有的程序中；当我尝试从主类中运行其他程序时，GUIPanel 不会运行，但是当我不执行它时它会运行（如果这有任何意义的话）。
这就是我运行程序时发生的事情
我希望输出打印到这个 GUIPanel（我必须删除对 TourServer 的调用才能让它运行），如果你在想“为什么不把它留在命令提示符下，你的 GUIPanel 中没有任何东西除了文本区域之外？”，那是因为我打算稍后添加更多内容：D
总之：我需要从 GUIPanel 类运行 TourServer 程序，当我尝试它时，它不会打开 GUI 面板本身
这是主要课程：

这是 TourServer 类
// TourServer.java
/*
The top-level Tour server, which waits for client connections
and creates TourServerHandler threads to handle them.
Details about each client are maintained in a TourGroup object
which is referenced by each thread.
Very similar to the multithreaded Chat server.
