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;}@Overridepublic 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>() {@Overridepublic int compare(card o1, card o2) {return o1.getSize()-o2.getSize();}});}
}
