Question

我正在尝试制作一个非常简单的黑杰克游戏，我在从阵列列表中抽取卡片并将它们放入玩家手中时遇到问题，并且经销商手中......

这就是我到目前为止所有愿意提供帮助的人都会非常感激。

我也意识到我很多人都没有以最有效的方式做到这一点......

CARDS ARRAY LIST

PLAYER＆amp;经销商手类

这里是我要填写dealPlayer（）＆amp; dealDealer（）有两张来自阵列的随机牌，我现在只是在一个树桩里似乎找不到任何可行的东西...在此先感谢您的帮助，如果我需要发布任何其他信息，请让我知道！

import java.util.ArrayList;

public class dealer {

    deck deck = new deck();
    String dealerTopCardString = "";
    card playerHandCard;
    card dealerHandCard;
    ArrayList<card> dealerHand = new ArrayList<card>();
    ArrayList<card> playerHand = new ArrayList<card>();

public void start() {
    dealerHand = new ArrayList<card>();
    playerHand = new ArrayList<card>();
}

public void dealPlayer() {
    //LOOKING FOR HELP HERE
}

public void dealDealer() {
    //LOOKING FOR HELP HERE
}

public String getPlayerHand() {

    String playerHandString = "";
    for (int i = 0; i < playerHand.size(); i++)
        playerHandCard = playerHand.get(i);
        card card = new card(playerHandCard.getValue(), playerHandCard.getSuit());
        playerHandString += "\n";
        playerHandString += card.getValue();
        playerHandString += "\t";
        playerHandString += card.getSuit();

        return playerHandString;

    }

public String getDealerHand() {

        String dealerHandString = "";
        for (int i = 0; i < dealerHand.size(); i++)
            dealerHandCard = dealerHand.get(i);
            card card = new card(dealerHandCard.getValue(), dealerHandCard.getSuit());
            dealerHandString += "\n";
            dealerHandString += card.getValue();
            dealerHandString += "\t";
            dealerHandString += card.getSuit();

            return dealerHandString;
    }

public String getDealerTopCard(){

    return getDealerTopCard;
}

public int getPlayerHandValue(){

    return getPlayerHandValue;
}

public int getDealerHandValue(){


    return getDealerHandValue;
}

public void resetDealerHand(){
    dealerHand.clear();
}

public void resetPlayerHand(){
    playerHand.clear();
}

}

Answer 1

当您发布问题时，say what you have tried通常是最佳做法。这样，其他人可以帮助您了解您可能出错的地方。

我将就如何解决问题向您提供一些一般性建议。如果您在实施它时遇到特定问题，可以提出一个新问题（或根据其相关程度更新此问题）。

在一个真正的二十一点游戏中，你可以将牌组洗牌，然后移除前4张牌。你可以在这里做同样的事情：

Shuffle the ArrayList
移除前4张牌以放入玩家/经销商手中。（也许你可以使用remove方法删除套牌中的第一个或最后一个元素。）

这看起来可能是家庭作业，因此您可能需要使用ArrayList。这不是最好的数据结构。如果您有选择，我会使用ArrayDeque代替。它具有高效的pop()和remove()方法，用于从集合中取出第一个或最后一个项目。

（提示：“deque”代表双端队列，但它的发音是“deck”。这是因为它在概念上就像一副纸牌......）

Answer 2

使用Collections#shuffle

来洗牌

Collections.shuffle(deck);

然后使用List#remove从牌组顶部获取下一张牌，所以这样就可以处理起手牌了

playerHand.add(deck.remove(0));   // top card to player
dealerHand.add(deck.remove(0));   // top card to dealer
playerHand.add(deck.remove(0));
dealerHand.add(deck.remove(0));
