一、三人扑克

想不想带上好朋友来上一局三人扑克呢。

二、具体实现

Card类

定义一个花色color变量和一个大小rank变量。

public class Card {
    public int rank;
    public String color;

    @Override
    public String toString() {
        return String.format("[%s,%d]",color,rank);
    }
}

生成52张牌

我们先买一副新牌

public class Cards {
    public static final String[] COLORS = {"♦","♥","♣","♠"};
    //输入52张牌
    public static List<Card> buyCard() {
        List<Card> list = new ArrayList<>(52);
        for (int i = 0; i < 4; i++) {
            for (int j = 1; j <= 13; j++) {
                String color = COLORS[i];
                int rank = j;
                Card card = new Card();
                card.color = color;
                card.rank =rank;
                list.add(card);
            }
        }
        return list;
    }
}    

我截取了部分图片，我们可以发现这是一副新牌，按照花色大小放着，我们玩扑克的时候肯定要打乱扑克牌。

打乱顺序

这个方法负责将扑克牌打乱

 public static void mixed(List<Card> cards) {
        for (int i = 51; i > 0; i--) {
            Random random = new Random();
            int j = random.nextInt(i);
            Card c = cards.get(i);
            cards.set(i,cards.get(j));
            cards.set(j,c);
        }
    }

发牌

public static void main(String[] args) {
        List<Card> list = buyCard();//获取新牌
        mixed(list);//把牌打乱
        List<List<Card>> lists = new ArrayList<>();
        lists.add(new ArrayList<Card>());
        lists.add(new ArrayList<Card>());
        lists.add(new ArrayList<Card>());
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                lists.get(j).add(list.remove(0));
            }
        }
        System.out.println("三个人的牌分别是: ");
        System.out.println(lists.get(0));
        System.out.println(lists.get(1));
        System.out.println(lists.get(2));
    }

三、完整代码

import java.util.ArrayList;
import java.util.List;
import java.util.Random;
public class Card {
    public int rank;
    public String color;

    @Override
    public String toString() {
        return String.format("[%s,%d]",color,rank);
    }
}
public class Cards {
    public static final String[] COLORS = {"♦","♥","♣","♠"};
    //输入52张牌
    public static List<Card> buyCard() {
        List<Card> list = new ArrayList<>(52);
        for (int i = 0; i < 4; i++) {
            for (int j = 1; j <= 13; j++) {
                String color = COLORS[i];
                int rank = j;
                Card card = new Card();
                card.color = color;
                card.rank =rank;
                list.add(card);
            }
        }
        return list;
    }
    public static void mixed(List<Card> cards) {
        for (int i = 51; i > 0; i--) {
            Random random = new Random();
            int j = random.nextInt(i);
            Card c = cards.get(i);
            cards.set(i,cards.get(j));
            cards.set(j,c);
        }
    }

    public static void main(String[] args) {
        List<Card> list = buyCard();//获取新牌
        mixed(list);//把牌打乱
        List<List<Card>> lists = new ArrayList<>();
        lists.add(new ArrayList<Card>());
        lists.add(new ArrayList<Card>());
        lists.add(new ArrayList<Card>());
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                lists.get(j).add(list.remove(0));
            }
        }
        System.out.println("三个人的牌分别是: ");
        System.out.println(lists.get(0));
        System.out.println(lists.get(1));
        System.out.println(lists.get(2));
    }
}
