一案例要求：

（由于暂时没有学到通信知识，所以只会发牌，不会设计打牌游戏）

二具体代码：

Ⅰ：主函数

package three;

public class test {
    public static void main(String[] args) {
        Room room=new Room();
        room.start();
    }
}

Ⅱ：实体类：

package three;

public class card {
    private String number;
    private String color;
    private  int size;

    public card() {
    }

    public card(String number, String color, int size) {
        this.number = number;
        this.color = color;
        this.size = size;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public String getColor() {
        return color;
    }

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

    public int getSize() {
        return size;
    }

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

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

Ⅲ操作类：

package three;

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

public class Room {
    private List<card> allcards=new ArrayList<>();
    public Room(){
        String []numbers={"3","4","5","6","7","8","9","10","J","Q","K","A","2"};
        String []color={"♠","♣","■","♥"};
        int size=0;
        for (String number : numbers) {
            size++;
            for (String s : color) {
                card a=new card(number,s,size);
                allcards.add(a);
            }
        }
        card a1=new card("","🃏",++size);
        card a2=new card("","🃏",++size);
        Collections.addAll(allcards,a1,a2);
        System.out.println("新牌"+allcards);
    }

    public void start() {
        Collections.shuffle(allcards);
        System.out.println("洗牌后"+allcards);
        List<card>xiaozhang=new ArrayList<>();
        List<card>xiaowang=new ArrayList<>();
        List<card>xiaochong=new ArrayList<>();
        for (int i = 0; i < allcards.size()-3; i++) {
            if(i%3==0){
                xiaozhang.add(allcards.get(i));
            }
            if(i%3==1){
                xiaowang.add(allcards.get(i));
            }
            if(i%3==2){
                xiaochong.add(allcards.get(i));
            }
        }
        sort(xiaozhang);
        sort(xiaowang);
        sort(xiaochong);
        System.out.println("小张"+xiaozhang);
        System.out.println("小王"+xiaowang);
        System.out.println("小冲"+xiaochong);
        List<card> left=allcards.subList(allcards.size()-3,allcards.size());
        xiaozhang.addAll(left);
        sort(xiaozhang);
        System.out.println("小张抢到地主牌后"+xiaozhang);

    }
    public void sort(List<card> a){
        Collections.sort(a, new Comparator<card>() {
            @Override
            public int compare(card o1, card o2) {
                return o1.getSize()-o2.getSize();
            }
        });
    }
}
