现在我正在用java开发一个国际象棋游戏，并且已经将整个游戏编写在一个java文件中而没有进行子类化，我希望我能得到一些帮助
我想将所有部分的动作分成新文件
有人可以告诉我该怎么做
这是下面的整个文件叫做ChessFrame，
我需要帮助将所有棋子移动到一个名为ChessMovement.java的单独文件中
我试过刚刚取出这个动作但是那打破了我真正可以与某个人展示的一切

感谢您的帮助

您将游戏逻辑与GUI元素混合在一起。您应该使用MVC的概念。在这种状态下折射您的程序是一个非常不明确的问题。
答案 1 :(得分：1)
您需要创建一个Piece类，它包含所有片段类型的子类。然后创建一个Factory PieceFactory.getPiece（pieceName，x pos，y pos，chessboard）来获取这些部分，并在其上实现一个move（）方法，它接受你的新位置，并进行所有验证。这留下了用于在此处渲染移动的UI逻辑，但是将移动逻辑向下推入到片段对象中。
稍后您可能会更改此内容以创建一个ChessBoard对象，这将允许您通过它的x，y坐标获得一个片段，因此不知道该片段的名称。 chessBoard.getPiece（x，y）.move（newX，newY）;这将允许你验证移动，加上处理捕获等，回到董事会去除相反的部分。
