用java语言编写一个4个玩家玩的2副扑克牌的游戏

好的，下面是一个简单的Java代码示例，实现了4个玩家玩2副扑克牌的游戏。该游戏使用了Java的面向对象编程思想，包括类和对象的概念。

import java.util.ArrayList;
import java.util.Collections;

public class PokerGame {
    public static void main(String[] args) {
        // 创建两副扑克牌
        Deck deck1 = new Deck();
        Deck deck2 = new Deck();
        // 洗牌
        deck1.shuffle();
        deck2.shuffle();
        // 创建四个玩家
        Player player1 = new Player("Player 1");
        Player player2 = new Player("Player 2");
        Player player3 = new Player("Player 3");
        Player player4 = new Player("Player 4");
        // 发牌
        for (int i = 0; i < 13; i++) {
            player1.addCard(deck1.dealCard());
            player2.addCard(deck2.dealCard());
            player3.addCard(deck1.dealCard());
            player4.addCard(deck2.dealCard());
        }
        // 输出每个玩家的牌
        System.out.println(player1);
        System.out.println(player2);
        System.out.println(player3);
        System.out.println(player4);
    }
}

class Card {
    private String suit; // 花色
    private String rank; // 点数

    public Card(String suit, String rank) {
        this.suit = suit;
        this.rank = rank;
    }

    public String getSuit() {
        return suit;
    }

    public String getRank() {
        return rank;
    }

    public String toString() {
        return rank + " of " + suit;
    }
}

class Deck {
    private ArrayList<Card> cards;

    public Deck() {
        cards = new ArrayList<Card>();
        String[] suits = {"Clubs", "Diamonds", "Hearts", "Spades"};
        String[] ranks = {"2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace"};
        for (String suit : suits) {
            for (String rank : ranks) {
                Card card = new Card(suit, rank);
                cards.add(card);
            }
        }
    }

    public void shuffle() {
        Collections.shuffle(cards);
    }

    public Card dealCard() {
        if (cards.size() == 0) {
            return null;
        }
        return cards.remove(0);
    }
}

class Player {
    private String name;
    private ArrayList<Card> hand;

    public Player(String name) {
        this.name = name;
        hand = new ArrayList<Card>();
    }

    public void addCard(Card card) {
        hand.add(card);
    }

    public String getName() {
        return name;
    }

    public String toString() {
        String result = name + ":\n";
        for (Card card : hand) {
            result += "  " + card.toString() + "\n";
        }
        return result;
    }
}

该程序包括三个类：Card、Deck和Player。Card类表示一张扑克牌，包括花色和点数；Deck类表示一副扑克牌，包括创建、洗牌和发牌等操作；Player类表示一个玩家，包括添加牌和输出牌等操作。

程序首先创建两副扑克牌，并洗牌。然后创建四个玩家，分别发牌，最后输出每个玩家的牌。
