我必须采用在大多数赌场二十一点游戏中常见的Split手部功能。我遇到的问题是调用并比较玩家手中的两张牌。每当我尝试调用作为Player对象一部分的Card数组的元素时，它就会给我带来错误。该计划也不会扣除或添加投注到玩家的余额。
我还需要在每个玩家玩游戏时为其添加一个基本的统计和提示系统。
任何帮助我如何使这个更有效或任何你看到的错误将不胜感激。
答案 0 :(得分：0)
直到我放弃的地方，这些是我的笔记。我放弃了，因为糟糕的格式化正在破坏我阅读代码的努力。
另外，在我看来，格式较差的地区也是包含最荒谬的代码的地区，所以我开始怀疑有一些可疑的东西，比如可能涉及两个程序员，一个人不明白蹲下试图完成另一个可能理解了几件事的人的工作。
我建议使用ArrayList<Card>而不是Card[]，但如果您的作业要求数组，那么很好，坚持使用数组。
我建议你一直停止使用this.，但如果你的教授要求你，那么哦，你能做什么。
您的整个isEmpty()方法可以编码为{ return numCards == 0; }，但您所拥有的并没有错，这只是愚蠢。
你的西装和面孔应该是enum而不是大的常数组。这不是一个错误，但你的面部常量从1而不是0开始的事实可能会导致问题。
您的suitToString()应该使用switch语句实现。 （不是错误。）
你的Card.mySuit和Card.cardValue会员毫无意义，但他们似乎并没有被使用。
Card.mySuit似乎属于Suit类型。那么，最后，您是否有Suit枚举？你在向我们隐瞒什么吗？
在printHand()中你真的应该使用StringBuilder。但是，不是错误。
如果您遇到错误， 不 System.err.printf()和exit()。而是抛出异常。但是，不是错误。
以下代码没有意义：
private int face;
public int getFace()
{
this.face = face;
return face;
}
和 对于玩家来说，它甚至没有任何意义。 幸运的是，它永远不会被使用。摆脱它。
就这样你知道，这个：
Player a;
a = new Player(playerName, startingBalance);
player[i] = a;
简化为：
Player a = new Player(playerName, startingBalance);
player[i] = a;
简化为：
player[i] = new Player(playerName, startingBalance);
请不要浪费时间强迫我们阅读无意识的代码行。
在main()中你声明了一些double[] playersBank，但每个玩家都有自己的bankRoll，这对我没有任何意义。我可能错了，但我认为其中一个需要去。我建议摆脱playersBank。这可能是一个错误。
是的，当然程序没有扣除或添加投注到玩家的余额，你还没有编写代码来做到这一点。但对于已经编写了如此多代码的人来说，这应该是微不足道的。您有没有机会从其他人那里复制此代码，而不知道它是如何工作的以及它想要做什么？
无论如何，在bets[i]= currentBet;附近，你需要从玩家的余额中减去currentBet。这是一个错误。
另外，我建议丢失bets[]数组并将currentBet移到Player类。但那不是错误。
对于分手功能，您可能需要将Card[] splitHand成员添加到Player，如果非空，则表示玩家已分手。而且您需要编写要求它的代码，然后执行它。我们在这里发现人们遇到的问题＆＃39;代码和建议解决方案，我们通常不会写人。代码。
