用Java写一个简单的扑克牌比大小游戏

好的，以下是一个简单的扑克牌比大小游戏的 Java 代码：

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

public class PokerGame {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入玩家数量：");
        int playerCount = scanner.nextInt();
        scanner.nextLine(); // 读取换行符

        List<String> deck = generateDeck();
        Collections.shuffle(deck); // 洗牌

        List<List<String>> players = new ArrayList<>();
        for (int i = 0; i < playerCount; i++) {
            players.add(new ArrayList<>());
        }

        for (int i = 0; i < 5; i++) {
            for (int j = 0; j < playerCount; j++) {
                String card = deck.remove(0);
                players.get(j).add(card);
            }
        }

        for (int i = 0; i < playerCount; i++) {
            System.out.printf("玩家%d的牌为：%s\n", i + 1, players.get(i));
        }

        int maxScore = 0;
        int winner = -1;
        for (int i = 0; i < playerCount; i++) {
            int score = calculateScore(players.get(i));
            System.out.printf("玩家%d的得分为：%d\n", i + 1, score);
            if (score > maxScore) {
                maxScore = score;
                winner = i;
            }
        }

        System.out.printf("玩家%d获胜！\n", winner + 1);
    }

    private static List<String> generateDeck() {
        List<String> deck = new ArrayList<>();
        String[] suits = {"♠️", "♥️", "♣️", "♦️"};
        String[] ranks = {"2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A"};
        for (String suit : suits) {
            for (String rank : ranks) {
                deck.add(rank + suit);
            }
        }
        return deck;
    }

    private static int calculateScore(List<String> hand) {
        int score = 0;
        for (String card : hand) {
            String rank = card.substring(0, card.length() - 1);
            switch (rank) {
                case "J":
                case "Q":
                case "K":
                    score += 10;
                    break;
                case "A":
                    score += 11;
                    break;
                default:
                    score += Integer.parseInt(rank);
            }
        }
        return score;
    }
}

运行程序后，首先要输入玩家数量，然后程序自动洗牌、发牌、计算得分和比较大小，最后输出获胜玩家。每个玩家的牌和得分也会被输出。

这个简单的扑克牌比大小游戏只考虑了单张牌的大小，没有考虑花色和牌型等因素。如果需要更加复杂的游戏规则，可以在此基础上进行扩展。
