在完成我的学校二十一点游戏的最后阶段。在尝试对逻辑进行编程时，我似乎遇到了问题。

基本上，只有当他们的牌 <= 16 时，庄家才会打牌，由于某种原因，为此的 if 语句不起作用，庄家只是一直打牌或一直打牌，不管他们的牌值如何……我知道这可能很简单，但我似乎找不到。

此外，当他的牌面值超过 21 时，庄家也不会爆牌。

主要（问题在这里）

import java.util.Scanner;
import java.util.ArrayList;

public class game {
public static String name;

public static void main(String[]args){

    deck doc = new deck();
    dealer dealer = new dealer(doc);

    Scanner nameScanner = new Scanner(System.in);

    int money = 200;

    System.out.println("Welcome to BlackJack!" + "\n\n" + "Your balance: $" + money + "\n\n" + "What is your name? ");
    name = nameScanner.nextLine();

    dealer.start();

    dealer.dealDealer();
    dealer.dealPlayer();
    dealer.dealDealer();
    dealer.dealPlayer();


    boolean dealerStay = false;
    boolean playerStay = false;
    boolean allStay = false;
    boolean tie = false;

    while(true){

        System.out.println(dealer.toString());
        Scanner gameScanner = new Scanner(System.in);   

        System.out.println("\nWould you like to Hit(H) or Stay(S)? ");

        String hos = gameScanner.nextLine();

        //Players & Dealer hit logic
        if(hos.equalsIgnoreCase("h")) {
            dealer.dealPlayer();
        }
        //Player bust
        if(dealer.getPlayerHandValue() > 21){
            System.out.println("*****YOU LOSE\n*****You bust with " + dealer.getPlayerHandValue() + "\n*****Dealer wins by default");
            break;
        }
        //Stay logic
        if(hos.equalsIgnoreCase("s")){
            playerStay = true;
        }
        //Dealer hit logic PROBLEM HERE
        if(playerStay == true && dealer.getDealerHandValue() <= 16){
            dealer.dealDealer();
            System.out.println("\n*****Dealer hit\n");
        }
        //Dealer stay logic PROBLEM HERE
        if (playerStay == true && dealer.getDealerHandValue() > 16){
            System.out.println("\n*****Dealer stayed\n");
            dealerStay = true;
        }
        //Dealer bust PROBLEM HERE
        if(dealer.getDealerHandValue() > 21){
            System.out.println("*****YOU WIN\n *****Dealer busts");
            break;
        }





        }
    }
}

构造函数（如果需要）

    for (card a : playerHand) {
        String c = a.getValue();
        if (c.equals("J")) {
            playerHandValue += 10;
        }

        else if (c.equals("Q")) {
            playerHandValue += 10;
        }

        }
    }

    int valueOfCards = playerHandValue;
    return valueOfCards;
}

        }
    }

    int valueOfCards = playerHandValue;
    return valueOfCards;
}

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

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

}

让我知道我是否可以为您提供其他任何东西，在此先感谢您的帮助！

您的方法getDealerHandValue()是使用 ArrayList playerHand。

它应该使用dealerHandArrayList。

更好的方法是定义一个将列表作为参数的方法，然后使用适当的列表调用它，例如

public int getHandValue(List<card> theHand) {
    int handValue = 0;        

    for (card a : theHand) {
        // Your logic
    }
    return handValue;
}

然后打电话getHandValue(playerHand)或getHandValue(dealerHand)
