慕课网-简易扑克牌游戏 思路清晰 简易版

游戏流程

1. 创建一副全新的扑克牌；
2. 加入两名玩家；
3. 两位玩家各自随机抽取一张扑克牌；
4. 比较点数大小，分出胜负。

对象

1. 卡牌类

import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;

public class Cards {
    
    private final String[] suit = {
    "黑桃", "红桃", "方块", "梅花"};
    private final String[] points = {
    "A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};
    private String[][] cards;
    //便于后续排序
    private Map<String,Integer> compare;
    //构造函数
    public Cards() {
    
        cards = new String[suit.length][points.length];
        compare=new HashMap<>();
        for(int i=0;i<points.length;i++){
    
            compare.put(points[i],i);
        }
    }
    //创建扑克牌
    public void CreatCards() {
    
        for (int i = 0; i < suit.length; i++) {
    
            for (int j = 0; j < points.length; j++) {
    
                cards[i][j] = suit[i] + points[j];
            }
        }
    }
    //得到扑克牌
    public String[][] getCards(){
    
            return this.cards;
    }
    public Map<String,Integer> getMap(){
    
        return this.compare;
    }
    //打印扑克牌
    public void printCards() {
    
        for (String[] each : cards) {
    
            System.out.println(Arrays.toString(each));
        }
    }
}

2.玩家类

public class Players {
    
    private final int cardsNumber=1;
    private String name;
    private String card;
    //构造函数
    public Players(String name){
    
        this.name=name;
    }
    //得到名字
    public String getName(){
    
        return this.name;
    }
    得到卡牌
    public String getCard(){
    
        return this.card;
    }
}

游戏

import java.util.Map;
import java.util.Scanner;

public class TestCards {
    
    public static void main(String[] args) {
    
        //新的扑克牌
        System.out.println("---创建扑克牌---");
        Cards aCards = new Cards();
        aCards.CreatCards();
        aCards.printCards();
        String[][] cards = aCards.getCards();
        //客户1
        Scanner in = new Scanner(System.in);
        System.out.print("请输入第一位玩家姓名：");
        String name1 = in.nextLine();
        Players player1 = new Players(name1);
        //客户2
        System.out.print("请输入第二位玩家姓名：");
        String name2 = in.nextLine();
        Players player2 = new Players(name2);
        //发牌
        System.out.println("---随机抽牌---");
        //玩家1的牌
        System.out.print(player1.getName() + "的牌：");
        String card1 = cards[(int) (Math.random() * (cards.length - 1))][(int) (Math.random() * (cards[0].length - 1))];
        System.out.println(card1);
        //玩家2的牌
        System.out.print(player1.getName() + "的牌：");
        String card2 = cards[(int) (Math.random() * (cards.length - 1))][(int) (Math.random() * (cards[0].length - 1))];
        while(card2.equals(card1))
            card2 = cards[(int) (Math.random() * (cards.length - 1))][(int) (Math.random() * (cards[0].length - 1))];
        System.out.println(card2);
        //比较大小
        System.out.println("---一决胜负---");
        Map<String,Integer> map=aCards.getMap();
        int condition=map.get(card1.substring(2,3)).compareTo(map.get(card2.substring(2,3)));
        switch(condition){
    
            case 1:
                System.out.println(player1.getName()+"胜利！");
                break;
            case 0:
                System.out.println(player1.getName()+"和"+player2.getName()+"打平");
                break;
            case -1:
                System.out.println(player2.getName()+"胜利！");
                break;
        }
    }
}

精简（不足）之处

• 用随机抽牌代替洗牌过程；
• 每人只抽了一张牌；
• 输入姓名缺少了异常捕捉；
• 比较大小没有利用Comparable等接口。
