java - 如何为我的 Java 纸牌游戏引用数组中的索引位置

Question

我正在为一个 Java 小组项目(纸牌游戏)开发这个 House 对象。

我已将需要帮助的部分放在 v 和 ^ 分隔线中。

我编写了一些起始代码来展示我想做的事情。我希望玩家选择他们想要他们的A牌是高还是低。我只是不确定如何进行推荐/通话；由于某种原因，我一直对数组感到害怕并与之斗争。

我遇到的问题是引用数组中的特定位置。在本例中，它引用 Ace 卡的位置。

/**

public class House
{
    private double currentBet;  // Player's current bet
    private double pot;         // Amount of the pot in play
    private Deck deck;          // The card deck to be used
    private Card firstCard;     // First card to be dealt
    private Card secondCard;    // Second card to be dealt
    private Card thirdCard;     // Third card to be dealt

    /**
      * Receives the current player.  Only receives a player that is active.
      * Will display two cards, get a bet amount from the player, and then
      * display the third card.  Pot amount and player's bankroll will be 
      * adjusted depending on whether the player wins or loses their bet.

    public void playHand(Person currentPlayer)
    {
        // If current player is not active, return
        if (!currentPlayer.getActiveplayer())
        {
            return;
        }

        // Deal first card and second card; make sure they are different cards
        do
        {
            firstCard = dealCard();
            secondCard = dealCard();

            // If either card is an ACE, ask player if they want it to be high or low
            Scanner keyboard = new Scanner(System.in);
            if (firstCard.compareTo(index ACE of deck array) == 0 ||

                                   + "or press 0 for low."  );
                int ace = keyboard.nextInt();

                if (ace == 1)
                {
                    index ACE of deck array equals 11
                }
                else if (ace == 0)
                {
                    index ACE of deck array equals 1
                }
                else
                {
                    System.out.println("Invalid entry! Please enter 1 for high " 
                                        + "or 0 for low.");
                }
            }

        }
        while (firstCard.compareTo(secondCard) == 0);

        // Display first card and second card
        System.out.println("First card drawn: " + firstCard);
        System.out.println("Second card drawn: " + secondCard);

        // Get the current player's bet

        }

            thirdCard.compareTo(secondCard) == 0)
        {
            // If thirdCard is equal to firstCard or secondCard
            // Player loses double their bet to the pot
            currentPlayer.setBankroll(2.0 * -currentBet); // Decrease player bankroll
            pot = pot + (currentBet * 2.0);               // Update pot
            System.out.println("Ouch, you lose double your bet!");
        }
        else if (((thirdCard.compareTo(firstCard) == -1) &&  // thirdCard < firstCard
                  (thirdCard.compareTo(firstCard) == 1)) ||  // thirdCard > firstCard
                 ((thirdCard.compareTo(secondCard) == -1) && // thirdCard < secondCard
                  (thirdCard.compareTo(secondCard) == 1)))   // thirdCard > secondCard
        {
            // If thirdCard is in between firstCard and secondCard
            // Player wins bet; bet gets added to their bankroll
            currentPlayer.setBankroll(currentBet);  // Increase player bankroll
            pot = pot - currentBet;                 // Update pot
            System.out.println("Nice, you won this hand!");
        }
        else
        {
            // If thirdCard is not in between firstCard and secondCard
            // Player loses their bet to the pot
            currentPlayer.setBankroll(-currentBet);  // Decrease player bankroll
            pot = pot + currentBet;                  // Update pot
            System.out.println("Sorry, you lost this hand!");
        }  
    }

这是 Deck 类的一段代码。这是另一位团队成员写的:

  public class Deck {
    private Card[] deck;
    private int currentCard; //index of next card to be dealt
    private int remainingCards;
    private BufferedImage tempCardImage;


    /**
     * Constructor to build a deck of cards
     */
    public Deck () throws IOException
    {
    String[] Faces = {"2", "3", "4", "5", "6", "7",
                        "8", "9", "10", "Jack", "Queen",
                        "King", "Ace"};
    String[] Suits = {"Diamonds", "Clubs", "Hearts", "Spades"};

    deck = new Card[52];
    currentCard = 0;

Answer 1

您当前正在将 Card 对象与 String 进行比较，这是行不通的。在您的 Card 类中，您需要一个访问器方法来访问表示脸部的字符串。

更改索引是一种非常令人困惑的更改值的方法，因此请向 Card 类添加一个名为 value 的 int 字段、setValue() 更改器(mutator)方法和 getValue() 访问器方法。

完成所有操作后，这就是箭头之间的代码。

Scanner in = new Scanner(System.in);
if(firstCard.getFace().equals("Ace")){
    int aceControl=0;
    while(aceControl!=1&&aceControl!=11){
        System.out.print("Type 1 if your Ace is low and 11 if it is high");
        aceControl=in.nextint();
    }
    firstCard.setValue(aceControl);
}
if(secondCard.getFace().equals("Ace")){
    int aceControl=0;
    while(aceControl!=1&&aceControl!=11){
        System.out.print("Type 1 if your Ace is low and 11 if it is high");
        aceControl=in.nextint();
    }
    secondCard.setValue(aceControl);
}

如果您有任何疑问，请随时询问。我希望这会有所帮助。
