Poker mini game:
(Recommended tutorial: java course)
Introduction to game play: Define five People When playing poker, the gameplay is that 5 people each draw 4 cards from a deck of playing cards without a king. There are four types of cards: ♥, ♣, ♠, ♦. The size of the cards ranges from 1 to 13. (For simplicity here, only 1-5 are taken).
1. Whichever player has the Ace of Spades in his hand wins.
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<Player> 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<Card> 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<n;i++){//一共发n轮牌 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<Card> 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. Let each player draw a card from his next player's hand in turn, and then look for ♠A. If he finds ♠A, he wins.
//添加打印手牌的方法 public static void printPlayerHandCard(List<Player> 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<playerList.size();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. Yu Meiren is the God of Gamblers. She has the ability to change cards: once she does not have ♠A in her hand, she can change the first card into ♠A. (Before exchanging cards, you have the opportunity to change once; after exchanging cards, you have the opportunity to change once)
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);
Define a new class of players:
package poker; import java.util.ArrayList; import java.util.List; public class Player { public List<Card> cardList=new ArrayList<>(); public String name; public Player(String name){ this.name=name; } }
Define a class of playing cards:
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); } }
Note:
(1) To redefine the override of the comparison equality method.
(2) Pay attention to the writing of the foreach method.
