## 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) {

            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));
        }
    }
