请使用Java代码写一个斗地主小游戏

以下是一个简单的斗地主小游戏的Java代码实现，其中使用了Java集合类和随机数生成器：

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Scanner;

public class DouDiZhuGame {
    public static void main(String[] args) {
        // 初始化一副扑克牌
        List<String> poker = new ArrayList<>();
        String[] colors = {"♠", "♥", "♣", "♦"};
        String[] numbers = {"2", "A", "K", "Q", "J", "10", "9", "8", "7", "6", "5", "4", "3"};
        for (String color : colors) {
            for (String number : numbers) {
                poker.add(color + number);
            }
        }
        poker.add("大王");
        poker.add("小王");

        // 洗牌
        Collections.shuffle(poker);

        // 发牌
        List<String> player1 = new ArrayList<>();
        List<String> player2 = new ArrayList<>();
        List<String> player3 = new ArrayList<>();
        List<String> bottomCards = new ArrayList<>();
        for (int i = 0; i < poker.size(); i++) {
            String card = poker.get(i);
            if (i >= poker.size() - 3) {
                bottomCards.add(card);
            } else if (i % 3 == 0) {
                player1.add(card);
            } else if (i % 3 == 1) {
                player2.add(card);
            } else if (i % 3 == 2) {
                player3.add(card);
            }
        }

        // 查看初始牌面
        System.out.println("玩家1的牌：" + player1);
        System.out.println("玩家2的牌：" + player2);
        System.out.println("玩家3的牌：" + player3);
        System.out.println("底牌：" + bottomCards);

        // 叫分
        Scanner scanner = new Scanner(System.in);
        int score = 0;
        int highestScore = 0;
        int highestScorePlayer = 0;
        for (int i = 1; i <= 3; i++) {
            System.out.print("玩家" + i + "是否叫分（0-不叫，1-1分，2-2分，3-3分）：");
            int callScore = scanner.nextInt();
            if (callScore > highestScore) {
                highestScore = callScore;
                highestScorePlayer = i;
            }
            if (callScore > 0) {
                score = callScore;
            }
        }
        System.out.println("最高分：" + highestScore + "，玩家" + highestScorePlayer + "叫的分最高");

        // 出牌
        List<String> playerCards = new ArrayList<>();
        if (highestScore > 0) {
            if (highestScorePlayer == 1) {
                playerCards.addAll(player1);
            } else if (highestScorePlayer == 2) {
                playerCards.addAll(player2);
            } else if (highestScorePlayer == 3) {
                playerCards.addAll(player3);
            }
            Collections.sort(playerCards);
            System.out.println("玩家" + highestScorePlayer + "先出牌");
            System.out.println("玩家" + highestScorePlayer + "的牌：" + playerCards);
            System.out.print("请玩家" + highestScorePlayer + "出牌：");
            String playedCard = scanner.next();
            playerCards.remove(playedCard);

            while (!playerCards.isEmpty()) {
                System.out.print("请玩家" + (highestScorePlayer % 3 + 1) + "出牌：");
                String nextPlayerCard = scanner.next();
                if (playerCards.contains(nextPlayerCard)) {
                    playerCards.remove(nextPlayerCard);
                    highestScorePlayer = highestScorePlayer % 3 + 1;
                } else {
                    System.out.println("出牌不符合规则，请重新出牌");
                }
                if (playerCards.isEmpty()) {
                    System.out.println("玩家" + highestScorePlayer + "赢了");
                }
            }
        } else {
            System.out.println("无人叫分，结束游戏");
        }
    }
}

这个小游戏实现了洗牌、发牌、叫分、出牌的基本功能，玩家可以通过命令行输入来进行操作。需要注意的是，这只是一个简单的示例，实际的斗地主游戏还需要考虑更多的细节和规则。
