Question

我的黑杰克程序中有错误。我一直试着找了半个小时。它说“卡已经定义了”。由于某种原因，我的deal（）函数也不能正常工作。我将再次发布此信息以获取更多信息。有人可以帮忙吗？我是初学者。所以我有一个名为index的类，其主要方法是：

public static void main(String[] args){
    runGame(2);                                 
}

然后我有几个方法然后我跑了游戏：

public static void runGame(int n){
    Card[] newdeck=createCardArray();

    Card[] shuffleddeck = shuffle(newdeck); 
    Deck deck = new Deck(shuffleddeck);
    int[] players = createPlayers(n);
    int[] points = createPoints(n);


    for(int i = 0 ; i< players.length - 1; i++){
        Card a = deck.deal();
        Card b = deck.deal();
        updatePoints(players, points, i, a);
        updatePoints(players, points, i, b);
    }
    printPlayersPoints(players, points);
}

在该文件夹中我还有一个Card.class和Deck.class：如果你想看看我有以下链接。当我运行这个我得到一个错误我不知道我做了什么，但它改变了：

at Card.<init>(fullblk.java:4)
at index.createCardArray(index.java:19)
at index.runGame(index.java:104)
at index.main(index.java:3)

但由于某种原因，这次我收到了这个错误：

    Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    The constructor Deck(Card[]) is undefined
    The method deal() is undefined for the type Deck
    The method deal() is undefined for the type Deck

    at index.runGame(index.java:101)
    at index.main(index.java:3)

任何人都可以帮助我。

Answer 1

甲板课结束时的支撑问题：

public class Deck
{
    // your constructors and methods.
  }
}

Answer 2

你在Deck.java的末尾有一个额外的大括号（'}'）。

Answer 3

好吧，你在Deck类的末尾有一个额外的}（右括号），删除那个结束括号编译。你应该好。

public class Deck
{
    // your constructors and methods.
  }
}
