Java学习之模拟纸牌游戏

• 首先放上测试效果图

---

---

• 设计框架

---

---

• 具体的代码实现

---

• 创建玩家类

  ---

public class Player implements Comparable<Player>{
    int id;
    String name;
    List<Card> cardList;
    Integer maxCard;
    public Player(int id, String name){
        this.id = id;
        this.name = name;
        this.cardList = new ArrayList<Card>();
    }
    public int compareTo(Player o) {
        return this.maxCard.compareTo(o.maxCard);
    }
}

---

• 创建扑克牌类

  ---

public class Card implements Comparable<Card>{
    Integer id;
    String value;
    public Card(Integer id, String value) {
        this.id = id;
        this.value = value;
    }
    public int compareTo(Card o) {
        return this.id.compareTo(o.id);
    }    
}

• 创建进行游戏类

  ---

public class PlayCards {
    
    Scanner console;
    List<Card> cardlist;
    Map<Integer, Player> playermap;
    List<Card> shufflelist;

        cardlist = new ArrayList<Card>();
        playermap = new HashMap<Integer, Player>();
        shufflelist = new ArrayList<Card>();
    }
//创建扑克牌的方法

        System.out.println("------创建扑克牌------");
        String[] head = {"方片","梅花","红桃","黑桃"};
        String[] number = {"2","3","4","5","6","7","8","9","10","J","Q","K","A"};
        int id = 0;
        for (int i = 0; i < 13; i++) {
            for (int j = 0; j < 4; j++) {
                String tempstr = head[j] + number[i];
                Card card = new Card(id++, tempstr);
                cardlist.add(card);
            }
        }
        System.out.println("------扑克牌创建成功！------");
        System.out.println("*********************************************");

        System.out.println("\n**********************************************");
        

    }
//进行洗牌的方法

• 创建初始类

  ---

public class Initial {
    
    public static void main(String[] args) {
        Scanner  input = null;
        int i = 0;
        while(true) {
            System.out.println("按  任意数字  开始游戏");
            try {
                input = new Scanner(System.in);
                i = input.nextInt();    
                break;
            }catch(InputMismatchException e) {
                System.out.println("请按要求输入！！！");
            }
        }
        PlayCards playcards = new PlayCards();
        playcards.creatCard();
        playcards.shuffle();
        playcards.creatPlayer();
        playcards.sendCardToPyer();
        playcards.whoIsWinner();
        System.out.println("欢迎下次游戏！！！");
        System.exit(0);

        if (input != null) {
            input.close();
            input = null;
        }
    }
}
