第一个基于文本的Java程序

我正在学习Java，这是我的第一个大项目。我正在使用Java设计一个基于文本的国际象棋游戏。我成功地完成了铸造工作，但由于某种原因，我无法让兵移动。我想分享其余的代码，但我不能，因为字符的限制，但我想通过DM发送整个程序给你

        }
        return pieceDevour;
    }
}

isMoveValid将始终返回true

    boolean pieceMove1 = false;
    boolean pieceMove2 = false;
    boolean pieceMove3 = false;
    boolean pieceMove4 = false;
    pieceMove1 = true;
    pieceMove2 = true;
    pieceMove3 = true;
    pieceMove4 = true;
    return pieceMove1  || pieceMove2 || pieceMove3 || pieceMove4;

---

计算最后一条语句时，pieceMove1到4都将为true，且true或true或true或true等于true。我甚至不知道您想在这里完成什么，所以我无法告诉您如何修复它，但一般来说，您应该重新考虑如何构造数据类型，以及哪个类实际上需要哪些信息。

您有问题吗？那么您的问题是什么？您将国际象棋设计为基于文本的Java程序？请分享代码。我会很惊讶的。哇，下棋了。你使用JavaFX吗？或者说基于文本的方法……国际象棋很难，但对语言学习者来说也是一项很好的任务。但是，除非您展示代码的相关部分，否则我们无法真正帮助您。另外，我建议您尽快学习如何使用调试器。
