嘿，目前我正在开发一款国际象棋游戏，但犯了一个错误，将所有 java 代码放在一个 java 文件中
我需要帮助将我的代码分割成更易于管理的部分
我希望有人能告诉我如何取出所有的棋子 Action 并将它们放入一个单独的文件中，然后链接回主文件？
我自己尝试过，但最终只是破坏了游戏
这是完整的凌乱的java文件，目前我只编码了一些部分，所以我想如果不解决这里可怕的架构，我不会进一步

您所追求的需要重构您的代码。我建议您在开始重构之前编写一些测试来验证您的工作逻辑。一旦您认为您的代码有足够的覆盖范围，就开始一次重构一小段代码(一次仅重构一小段代码)。每次进行更改后，请运行测试以查看是否损坏了任何内容。重复进行小的更改和运行测试的过程，直到您满意为止。
