因此，我一直在做一个21点计划，由于某种原因，我无法让“另一张卡y/n”正常工作，而且投注系统似乎也不起作用。另外，我也不太确定布尔方法-idk在main中的何处调用它。任何提示都将不胜感激

我已经试着换掉whiles/if，结果一切都变得一团糟。我也尝试过使方法无效，但我需要它返回userWins TRUE或FALSE。。因为这是一场游戏。。你知道吗

用户似乎也不会输给经销商，我预计会发生一些损失。我也希望“另一张卡”中的（y/n）能起作用，但“n”什么也不起作用。

我认为您唯一的问题是您试图返回userWin布尔值的方式：

 public static boolean playBlackjack(boolean userWins)

将其更改为（并在调用时删除输入参数）

当用户丢失时返回false，否则返回true
