其他一切正常，除了我遇到打印出卡片的问题（如果他们'击中'）因为我不知道玩家绘制什么牌以及哪个牌手取出什么牌，它从8开始前七张牌都被抽出但我不知道哪位牌手得到了什么以及有多少牌。所以我试着用一种方法来打印每个玩家的手，但是我有很多麻烦，可以使用一些帮助。我想打印玩家在输出中获得的牌。我会发布我的卡片，播放器和BlackJackGame课程，因为我的经销商课程非常类似于播放器。

//问题是当打印卡片时，我打印出每个玩家拥有的前两张牌和已知的经销商。我遇到的问题是如果玩家或经销商'击中'，你可以看到玩家1我不知道哪些牌被击中/哪个玩家拥有它们并且想知道如何在Player类中使用一个方法打印每个玩家的手牌，包括经销商和他们输出的牌。这就是我需要帮助的地方。其他一切都很好。
答案 0 :(得分：0)
首先，我建议使用switch语句而不是所有其他if if for rank，它会更加整洁：）
其次，在二十一点中，一张王牌并没有随机的＆＃34;价值1或11;这是一个11，除非它是11使球员破产。
第三，我会考虑使用甲板清单。那么你需要做的就是＆＃34; shuffle＆＃34;列表以及当您处理卡片时，从列表中删除顶部卡片并将其添加到播放器的手中。 （见Collections.Shuffle）
现在要解决最初的问题，你应该在播放器类中有一个List手。然后在播放器类中添加一个扩展方法来打印手;看起来应该是这样的：
public void printHand() {
ListIterator<Card> it = hand.listIterator();
if(it.hasNext())
System.out.print(it.next());
while(it.hasNext())
System.out.print(", " + it.next());
System.out.println();
}
