hello，我是忘鱼。

前言

斗地主小游戏，属于Collection体系综合案例，学习帮助我们加深理解。

一、案例所需要具备知识

常用Arraylist常用操作，和一些基础知识。代码注释很详细，简单但很重要。

二、代码

代码如下（示例）：

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

//斗地主游戏
public class GameDemo {
//    存取全部牌
public static List<Cards> allcards=new ArrayList<>();
//数量确定类型确定使用数组
static {
    String[] sizes={"3","4","5","6","7","8","9","10","J","Q","K","A","2"};
    String[] colors={"♣","♦","♥","♠"};
    int index=0;
//    List继承了collection,使用foreach循环简单;
    for (String size : sizes) {
        index++;
        for (String color : colors) {
//            使用变量接取
            Cards c=new Cards(size,color,index);
            allcards.add(c);
        }
    }
    Cards c1=new Cards("","小🃏",++index);
    Cards c2=new Cards("","大🃏",++index);
    Collections.addAll(allcards,c1,c2);
    System.out.println("新牌是："+allcards);
}
    public static void main(String[] args) {
//洗牌操作使用shuffle
        Collections.shuffle(allcards);
        System.out.println("洗牌后："+allcards);
//        定义三个player，使用集合简单
        List<Cards> player01=new ArrayList<>();
        List<Cards> player02=new ArrayList<>();
        List<Cards> player03=new ArrayList<>();
//       发牌，留三张底牌
        for (int i = 0; i < allcards.size()-3; i++) {

            Cards c=allcards.get(i);
//            求3的余数，0，1，2
            if(i%3==0){
                player01.add(c);
            }else if(i%3==1){
                player02.add(c);

            }else if(i%3==2){
                player03.add(c);
            }
        }
//        进行大小排序;,使用方法简单;
       sort(player01);
       sort(player02);
       sort(player03);
        System.out.println("玩家1"+player01);
        System.out.println("玩家2"+player02);
        System.out.println("玩家3"+player03);
//        还有三张底牌，差点忘了,直接截取用sublist   包前不包后
       List<Cards> lastthreeCards=allcards.subList(allcards.size()-3,allcards.size());
        System.out.println("底牌三张"+lastthreeCards);
    }

    private static void sort(List<Cards> playercards) {

    Collections.sort(playercards, new Comparator<Cards>() {
        @Override
        public int compare(Cards o1, Cards o2) {
            return o2.getIndex()- o1.getIndex();
        }
    });
    }
}
public class Cards {
    private String size;
    private String color;
//    定义牌自身属性大小判断本身大小
     private int index;
    public Cards() {
    }

    public Cards(String size, String color, int index) {
        this.size = size;
        this.color = color;
        this.index = index;
    }

    public String getSize() {
        return size;
    }

    public void setSize(String size) {
        this.size = size;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public int getIndex() {
        return index;
    }

    public void setIndex(int index) {
        this.index = index;
    }

    @Override
    public String toString() {
       return (size+color);
    }
}
