java - 简单的 Java 纸牌游戏 - 洗牌时遇到麻烦(数组)

Question

我是 Java 的新手，我很难理解如何洗牌数组(或我的牌组数组)。我试过使用 Random 类，但它对我不起作用。无论如何，这里是我创建的类:

纸牌游戏

import java.util.Random;

public class CardGame {

    public static void main(String[] args) {

        // final int SPADES = 0, HEARTS = 1, DIAMONS = 2, CLUBS = 3;
        final int ACE = 1, TWO = 2, THREE = 3, FOUR = 4, FIVE = 5, SIX = 6, SEVEN = 7, EIGHT = 8;
        final int NINE = 9, TEN = 10, JACK = 11, QUEEN = 12, KING = 13;

        Random rand = new Random();

        int[][] deck = {
                { ACE, TWO, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE, TEN, JACK, QUEEN, KING },

                player1.setHand(deck[i][randIndex]);
                player2.setHand(deck[i][randIndex]);
                player3.setHand(deck[i][randIndex]);
            }
        }

        System.out.println(player1.getHand());
        System.out.println(player2.getHand());
        System.out.println(player3.getHand());
    }
}

public class Player {

    final int MAX_HAND = 6;

    private String playerName;
    private int playerHand[] = new int[MAX_HAND];

    public Player(String name) {
        playerName = name;
    }

    public void setHand(int card) {

        int currentLength = playerHand.length;

        if (currentLength == MAX_HAND) {
            return;
        }

        playerHand[currentLength] = card;
    }

    public String getHand() {

        String cardN
                case 8:     cardNames += "Eight";   break;
                case 9:     cardNames += "Nine";    break;
                case 10:    cardNames += "Ten";     break;
                case 11:    cardNames += "Jack";    break;
                case 12:    cardNames += "Queen";   break;
                case 13:    cardNames += "King";    break;
            }

            if (i < playerHand.length - 2) {
                cardNames += ", ";
            }

        }

        return playerName + " has " + cardNames + " on his hand.";
    }
}

结果总是:

Name1 has Ace, Two, Three, Four and Five on his hand.
Name2 has Ace, Two, Three, Four and Five on his hand.
Name3 has Ace, Two, Three, Four and Five on his hand.

我在为 deck 的内部数组生成随机索引时做错了什么？

谢谢。

在 getHand() 方法中将 switch (i) 替换为 switch (playerHand[i]) 并调用 nextInt () 对每个玩家都适用，而不仅仅是每次迭代一次。

将setHand()改成

int index = 0;
public void addCard(int card) {
  if (index == MAX_HAND) {
            return;
  }
  playerHand[index++] = card;
}
