要用随机数组洗牌的话，可以使用Fisher-Yates算法。以下是将代码改为使用随机数组洗牌的示例：

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Random;

public class PokeGame {
    public static void main(String[] args) {
        List<String> pokerCards = new ArrayList<>();
        List<String> players = new ArrayList<>();
        HashMap<String, List<String>> playerHands = new HashMap<>();

        String[] suits = {"♠", "♥", "♣", "♦"};
        String[] ranks = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};

        for (String suit : suits) {
            for (String rank : ranks) {
                pokerCards.add(suit + rank);
            }
        }
        pokerCards.add("小王");
        pokerCards.add("大王");

        shuffleCards(pokerCards);

        players.add("小王");
        players.add("小李");
        players.add("小明");

        int numPlayers = players.size();
        int cardsPerPlayer = pokerCards.size() / numPlayers;
        int remainingCards = pokerCards.size() % numPlayers;

        int cardIndex = 0;
        for (String player : players) {
            List<String> hand = new ArrayList<>();

            for (int i = 0; i < cardsPerPlayer; i++) {
                hand.add(pokerCards.get(cardIndex));
                cardIndex++;
            }

            if (remainingCards > 0) {
                hand.add(pokerCards.get(cardIndex));
                cardIndex++;
                remainingCards--;
            }

            playerHands.put(player, hand);
        }

        for (String player : players) {
            System.out.println(player + "的手牌：" + playerHands.get(player));
        }
    }

    public static void shuffleCards(List<String> cards) {
        Random random = new Random();
        int size = cards.size();

        for (int i = size - 1; i > 0; i--) {
            int j = random.nextInt(i + 1);
            String temp = cards.get(i);
            cards.set(i, cards.get(j));
            cards.set(j, temp);
        }
    }
}

这里新增了一个`shuffleCards`方法，使用Fisher-Yates算法实现洗牌功能。在洗牌前将扑克牌存储在列表中，然后调用`shuffleCards`方法进行洗牌。最后输出每个玩家的手牌。
