//实现斗地主洗牌发牌功能 //1.准备一副牌 //2.洗牌 //3.发牌 //4.看牌 Java实现

以下是Java实现斗地主洗牌发牌功能的代码：

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

public class DouDiZhu {
    public static void main(String[] args) {
        // 1.准备一副牌
        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("小王");
        poker.add("大王");

        // 2.洗牌
        Collections.shuffle(poker);

        // 3.发牌
        Map<String, List<String>> players = new HashMap<>();
        List<String> player1 = new ArrayList<>();
        List<String> player2 = new ArrayList<>();
        List<String> player3 = new ArrayList<>();
        List<String> dipai = new ArrayList<>();
        for (int i = 0; i < poker.size(); i++) {
            String card = poker.get(i);
            if (i >= 51) {
                dipai.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);
            }
        }
        players.put("玩家1", player1);
        players.put("玩家2", player2);
        players.put("玩家3", player3);

        // 4.看牌
        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：" + dipai);
    }
}
