java - 二十一点获胜计算错误：数手数太多

Question

我正在尝试编写一个 Black Jack 模拟器程序。它询问用户要使用多少副牌，要模拟多少手牌，以及是否显示每手牌的结果。然后它运行基于 Black Jack 策略的程序，并且应该输出准确的赢/输百分比。但是，当我运行它时，我的玩家获胜次数/庄家获胜次数大于我想要玩的手数。

我认为这是我的推送和拆分方法，但我不确定如何解决它们。目前，我的 push 方法处理一手新手并确定手牌的赢家，然后将推动金额添加到玩家或庄家的胜利中。但是，这会将其视为当前手牌循环中的新手牌，因此给了我额外的手牌。我的拆分方法以类似的方式工作。任何关于如何正确重写它们的建议将不胜感激，谢谢。
