java - 使用骰子的二十一点游戏

Question

我正在用 Java 做一个项目，在该项目中我使用骰子来模拟二十一点游戏，但是，我遇到了一个我编写了错误代码的区域。如果玩家得分高于他，我正试图让经销商模拟动作。此外，我的checkWinner()方法似乎在错误的时间变得活跃。我不是要求任何人修复它，而是告诉我代码哪里出错了。

public class BlackJack {

    static PairOfDice cards = new PairOfDice();
    static Scanner scan = new Scanner(System. in );
    static int playerScore, dealerScore, player, dealer, tempScore;
    static boolean newGame;
    static String play, hit;


    public static void main(String[] args) {
        newGame();
        dealerRoll();
        playerRoll();

        // checkWinner();
    }

    public static void newGame() {

        System.out.println("Would you like to play blackjack? y or n?");
        play = scan.nextLine();

        if (play == "y"); {
            newGame = true;
        }
        if (play != "y") newGame = false;
    }

    public static void dealerRoll() {
        while (newGame) {
            cards.rollDice();
        }

        dealerScore = (cards.rollDice());
        System.out.println("Dealer score is: " + dealerScore);

        if (dealerScore <= 15 && playerScore > dealerScore) tempScore = cards.rollDice();
        System.out.println("The dice roll was: " + tempScore);
        dealerScore += tempScore;
        System.out.println("Dealer score is: " + dealerScore);

    }

    public static void playerRoll() {
        while (newGame) {
            cards.rollDice();
        }

        playerScore = (cards.rollDice());

        System.out.println("You total is " + playerScore);

        while (playerScore < 21 || playerScore < dealerScore) {

            System.out.println("Would you like to take a hit? y or n?");
            hit = scan.nextLine();
            if (hit.equals("y")) {
                tempScore = cards.rollDice();
                System.out.println("The dice roll was: " + tempScore);
                playerScore += tempScore;
                System.out.println("Your score is now: " + playerScore);

            }
            else if (hit.equals("n")); {
                checkWinner();
            }
        }
    }

    public static void checkWinner() {
        if (playerScore == 21) System.out.println("You win!");
        else if (dealerScore == 21) System.out.println("Sorry, Dealer has won!");
        else if (dealerScore > playerScore) System.out.println("Sorry, Dealer has won!");
        else if (playerScore > dealer) System.out.println("You win!");
        else if (playerScore > 21) System.out.println("Sorry you busted, Dealer has won!");

        else if (dealerScore > 21) System.out.println("Dealer has busted, You win!");
    }
}​

Answer 1

当您完成玩家回合时，您无法检查获胜者。只有在庄家转身后才这样做。

我重新编写了代码并想出了这个。任何意见将不胜感激。

    static String play= "y", yesPlay;
    static char hit;


    public static void main(String[] args)
    {
        newGame();



    }

    public static void newGame()
    {
        do
        {

            playerRoll();
            dealerRoll();
            stand();
            checkWinner();
            System.out.println("Would you like to play again? (Y/N)");
        } while (scan.next().toLowerCase().charAt(0) == 'y');

    }

    public static int takeHit()
    {
        return takeHit = cards.rollDice();

    }

            if(hit == 'n')
