【问题描述】：
我正在创建一个二十一点游戏，并使用了互联网上的教程来达到这一点。然而，我已经完成了教程，我不得不将其他类的所有方法添加到将要玩二十一点游戏的类中，但我不知道如何添加这些方法。 我想知道如何将所有方法添加到 P1 类中。

【问题讨论】：

为什么要向您的类中添加一个已经存在于另一个类中的方法？代码重复是相当可怕的。如果教程给了你那个想法，那么它就是一个非常糟糕的教程。如果所有教程教你的只是复制'n'粘贴一些代码 sn-ps 到你的项目中，仅此而已，那么这又是一个非常糟糕的教程，不值得被称为“教程”。如果是这样的话，我会建议寻找一个不同的教程，它不鼓励你只是复制'n'粘贴东西而不是操纵你觉得你已经学到了一些东西......

您的意思是您只想从其他方法中调用某些方法吗？
-
因此，从您要调用的一种方法开始。哪个是您需要调用的第一个方法，您需要从哪里调用它？看，我们不是在谈论编写代码行或其他代码行，而是关于如何设计程序的结构和控制流（程序的执行顺序）以及类实例之间的数据流。这与其说是代码编写问题，不如说是设计问题……
-
您必须创建类的实例并在表单中使用它们。例如：
deck deck = new deck();。然后在表单方法中，使用对象。例如：deck.ShuffleNewDeck();
