嘿目前我正在开发一款国际象棋游戏，但却犯了将我所有的java代码放在一个java文件中的错误
我需要帮助将代码切割成更易于管理的卡盘
我希望有人可以告诉我如何取出所有的棋子动作并将它们放在一个单独的文件中，然后链接回主文件？
我已经尝试过自己，但我最终还是打破了游戏
这是一个完整的杂乱的java文件，目前我只有一些编码的部分，所以我想如果没有解决这里可怕的架构我不会走得更远

您所需的内容需要重构您的代码。我建议你在开始重构之前编写一些测试来验证你的工作逻辑。一旦你认为你有足够的代码覆盖率，一次开始重构一小段代码（一次只有一小段代码）。在您进行每次更改后，运行测试以查看是否有任何损坏。重复进行小改动和运行测试的过程，直到您满意为止。
