Question

该计划的目的是展示扑克和桥牌手。那些在我运行程序的时候，我可以让它显示扑克描述然后退出。我希望它继续并显示一个扑克手，然后是桥牌描述和一个桥牌手。我觉得我的问题来自抽象的DeckOfCards课，但我真的不确定。

我将所有类放在同一个文件中，以便在编程时更容易理解和编辑。

当程序失败时会出现这些错误

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 52
at DeckOfCards.creatCardDeck(PlayCardGames.java:106)
at DeckOfCards.DeckOfCards(PlayCardGames.java:95)
at PlayCardGames.main(PlayCardGames.java:14)

这是自己的程序代码（感谢您编辑它以更好地格式化）

    import javax.swing.*;
    import java.util.Random;

    public class PlayCardGames {

       public static void main(String[] args) {


           Poker playPoker = new Poker();
           playPoker.DeckOfCards();
           playPoker.displayDescription();
           playPoker.deal();

           Bridge playBridge = new Bridge();

           playBridge.displayDescription();
           playBridge.deal();

你知道吗，我觉得这很简单：这是你的代码：

for (int suitCounter = 1; suitCounter < CARDS_IN_SUIT; suitCounter++)
        {
            for (int rankCounter = 1; rankCounter < CARDS_IN_SUIT; rankCounter++)
            {

我想也许应该是：

for (int suitCounter = 1; suitCounter < SUITS_IN_DECK; suitCounter++)
            {
                for (int rankCounter = 1; rankCounter < CARDS_IN_SUIT; rankCounter++)
                {

我似乎无法在我的主体中创建任何物体？
