扑克牌小游戏：

(推荐教程：java课程)

游戏玩法简介：定义五个People在玩扑克牌游戏，玩法是5个人从一副没有大小王的扑克牌中各抽取4张，牌的类型有四种：♥，♣，♠，♦。牌的大小为从1~13。(此处为了简单，只取1-5)。

1、黑桃♠A在哪名玩家手中，哪名玩家就获胜。package poker;

import java.util.ArrayList;

import java.util.Collections;

import java.util.List;

import java.util.Random;

import java.util.concurrent.Callable;

public class Game {

public static void main(String[] args) {

//定义5名玩家，使用List

List playerList=new ArrayList<>();

playerList.add(new Player("于美人"));

playerList.add(new Player("小婷子"));

playerList.add(new Player("小晨子"));

playerList.add(new Player("小艾"));

playerList.add(new Player("小珍子"));

//定义扑克牌顺序表

List cardList=new ArrayList<>();

//初始化扑克牌

initializeCards(cardList);

System.out.println(cardList);

//调用collections下的shuffle(洗牌)方法

//进行洗牌

Collections.shuffle(cardList);

//System.out.println("抽牌前，牌组中的牌：");

System.out.println(cardList);

//发牌

int n=2;//每名玩家发几张牌

for(int i=0;i

for(Player player:playerList){//每名玩家一次抽牌

Card card=cardList.remove(0);//从牌组中，抽一张牌出来

player.cardList.add(card);//把这张牌放到当前玩家的手中

}

}

System.out.println("现在牌组中剩余的牌：");

System.out.println(cardList);

System.out.println("交换牌之前：");

for(Player player:playerList){

System.out.printf("玩家[%s]的手牌是： %s%n",player.name,player.cardList);

}

//要找的牌，方法1

Card toFoundCard=new Card("♠",1);

for(Player player:playerList){

for(Card card:player.cardList){

//比较每张牌和要找的是否为同一张牌

if(card.equals(toFoundCard)){

System.out.println(player.name+"获胜");

return;

}

}

}

System.out.println("无人获胜");

}

//要找的牌，方法2

Card toFoundCard2=new Card("♠",1);

for(Player player:playerList){

if(player.cardList.contains(toFoundCard)) {

System.out.println(player.name + "获胜");

return;

}

}

private static void initializeCards(List cards){

for(String suit:new String[]{"♠","♥","♦","♣"}){

for(int rank=1;rank<=5;rank++){

Card card=new Card(suit,rank);

//把扑克牌放入牌组中

cards.add(card);

}

}

}

2、让每名玩家，依次抽取他的下家的一张手牌，然后再找♠A，找到♠A就获胜。//添加打印手牌的方法

public static void printPlayerHandCard(List playerList){

for(Player player:playerList){

System.out.printf("玩家[%s]的手牌是：%s%n",player.name,player.cardList);

}

}

//集体实现交换的过程

//交换牌

//每名玩家随机抽取下家的一张牌

Random random=new Random();

for(int i=0;i

Player currentPlayer=playerList.get(i);

//下家就是按照前后关系的下一个，最后一名玩家抽取第0个

Player nextPlayer=playerList.get(i!=playerList.size()-1?i+1:0);

//要取的牌的下标

int toDrawIndex=random.nextInt(nextPlayer.cardList.size());

//取牌

Card drawCard=nextPlayer.cardList.remove(toDrawIndex);

//放入当前玩家的手中

currentPlayer.cardList.add(drawCard);

}

System.out.println("交换牌之后：");

printPlayerHandCard(playerList);

3、于美人是赌神，她有变牌能力：她手中一旦没有♠A，她就可以把第一张牌变成♠A。(交换牌之前，有机会变一次；交换牌之后，有机会变一次)Card toFoundCard=new Card("♠",1);

//已知于美人的下标为0

Player 于美人=playerList.get(0);

if(!于美人.cardList.contains(toFoundCard)){

于美人.cardList.set(0,toFoundCard);

}

System.out.println("于美人第一次发功：");

printPlayerHandCard(playerList);

System.out.println("交换牌之后：");

printPlayerHandCard(playerList);

//此处交换牌过程省略。。。。。。。。。。。。。。

if(!于美人.cardList.contains(toFoundCard)){

于美人.cardList.set(0,toFoundCard);

}

System.out.println("于美人第二次发功：");

printPlayerHandCard(playerList);

定义玩家新的的一个类：package poker;

import java.util.ArrayList;

import java.util.List;

public class Player {

public List cardList=new ArrayList<>();

public String name;

public Player(String name){

this.name=name;

}

}

定义扑克牌的一个类：package poker;

import java.util.Objects;

public class Card {

public String suit;//花色

public int rank;//分值

//构造方法

public Card(String suit,int rank){

this.rank=rank;

this.suit =suit;

}

@Override

public String toString() {

return String.format("[%s%d]",suit,rank);

}

//重写比较相等的方法

@Override

public boolean equals(Object o) {

if (this == o) return true;

if (o == null || getClass() != o.getClass()) return false;

Card card = (Card) o;

return rank == card.rank &&

Objects.equals(suit, card.suit);

}

}

注意：

(1)要重新定义比较相等方法的重写。

(2)注意foreach 方法的写法。
