嘿，伙计们需要你的帮助来解决我的代码中出现的这个 java 问题，我已经创建了一个 GUI，它本质上被用作赛车模拟器，我的事件为我的 GUI 工作，除了我的 startrace 事件，这是一个启动按钮比赛，iv 只完成了比赛的第一部分，但没有成功，所以我想在继续之前解决问题。很难解释我显示代码会更容易（如下所示），我不想被勺子喂食，所以请不要开始给我糟糕的选票并说我没有提供足够的细节，因为我真的不知道是什么更多我可以说我要写的。我不知道问题是什么。当我调试它（因为我使用 Eclipse IDE）时，不起作用的部分只会使整个窗口变黑，大约一分钟内什么都没有显示，然后它会跳过大部分代码，甚至不做其余的工作。如果您需要更多信息，请询问我，我会告诉您我只是人类，不知道您希望我推迟的每个细节。我有很多课程，但它们可能会让你们更加困惑，所以我只粘贴我遇到问题的课程。
（注：SportCar- 是一个超类，有 5 个子类（Astonmatin、Audi、Ferrari、Porsche、Lamborghini））
（注意：Track 本身是一个带有 GUI 界面的类，它是一个大类，使用 SportsCar 及其子类中的变量和方法，所有这些方法和变量都不是问题）
（注意：问题出在actionPerformed（ActionEvent startrace）中）我希望我提供了足够的细节，欢迎任何帮助。提前谢谢你。
