java - 如何查明 Boggle 游戏中的逻辑错误以及如何修复它们？

Question

我的 Boggle 项目存在一些逻辑错误，但无法查明它们。我唯一能做的就是退出这个令人难以置信的游戏。谁能帮我吗？在此程序中，每当单击 JMenu 项新游戏时，我需要开始一个新游戏，每次单击 Shake Dice 按钮时要随机化的字母，包含提交单词 Jbutton 以及分数和当前单词 jlabels 的 Jpanel，以及每当单击提交单词按钮并更新分数时，当前单词标签就会更新。

Boggle 用户界面代码:

如果您在 Eclipse 等 IDE 中运行此程序，则可以放置 breakpoint ，然后运行您的应用程序并单步调试它，看看您的代码到底在做什么。

如果您无法访问调试器，您可以简单地使用 System.out.println() 调用来报告程序的当前状态 - 它并不优雅，但它可以工作。
