所以我对我的代码做了相当多的更改，现在它符合要求，但我得到了错误的总数，它总是认为玩家 2 获胜，甚至在它达到“20”之前。由于某种原因，直到玩家 2 滚动之后它才会读取玩家 1 的总得分，然后它不会计算玩家 2 的回合总数。当我之前进行更改时，一件事会开始工作，但另一件事会停止，所以我把它带回到编译后开始出现问题的地方。

最佳答案
玩家2/计算机的回合循环中出现错误。它位于第一个 if-else 循环中，位于 else 部分。
输入keyboard.nextLine();
应该是
input = Keyboard.nextLine();
纠正错误后，它工作正常。
此外，请密切注意编译错误，它们会向您指出哪些行生成了所述错误。
修改:
我认为这符合您的预期。

我还建议安装一个 IDE，例如 Netbeans或Eclipse 。 IDE 将使您的生活变得更加轻松，尤其是在处理格式和语法错误时。
