java - Netbeans JAR 未正常运行/打开

Question

我制作了一个带有 GUI 的 Hangman 游戏，我想为其构建一个 jar。在 Netbeans 中，我转到“运行”>“清理并构建项目”，它似乎构建了 jar 得很好。然而，当我真正去运行这个 jar 时，它所做的只是在屏幕左上角打开一个小窗口，而不是我设计的 GUI。不过，当我在 Netbeans 中运行 GUI 时，它会按预期打开。此外，当我尝试关闭它打开的这个窗口时，它实际上并没有结束 java 进程 - 它会保持运行状态，直到我从任务管理器结束它。下面将提供图片和代码。

这就是我运行 jar 时打开的内容 - 一个空框架，里面什么也没有。

这是应该打开的内容，也是我从 Netbeans 内部运行项目时打开的内容。

我尝试通过命令提示符运行它，它以相同的方式运行，没有错误。这是我的代码:
