一个简单的扑克牌小程序

新手一枚，最近刚学了java的集合框架，就拿来用一用（水平有限，欢迎交流）

游戏规则是：取两人各自手中点数最大的牌进行比较，点数大的赢；若两人各自的点数相等，则按花色比较。

感觉主要是以下几个方面花了一些时间，

（打乱扑克顺序的洗牌，通过自定义规则比较大小，一些集合与泛型的使用，通过try..catch捕获异常来限定登录ID为整数。）

首先是Card类：

/** * 扑克牌类 * @author admin * */public class Card{    //花色：suit//点数：figurepublic String suit;public String figure;/** * 形参构造器 * @param suit * @param figure */public Card(String suit,String figure){this.suit = suit;this.figure = figure;}}

玩家Player类：

import java.util.ArrayList;import java.util.List;/** * 玩家类 * @author admin * */public class Player {public int id;public String name;//手牌为扑克牌的集合,泛型设定为Cardpublic List<Card> cards;public Player(){this.cards = new ArrayList<Card>();}  }

最后是test：

import java.util.ArrayList;import java.util.List;import java.util.Scanner;public class Test {public Scanner console;//用于存放所有扑克的集合public List<Card> AllCards;Player player1 = new Player();    Player player2 = new Player();    String[] suits = {"方块","梅花","红心","黑桃"};String[] figures = {"2","3","4","5","6","7","8","9","10","J","Q","K","A"};public Test(){console = new Scanner(System.in);this.AllCards = new ArrayList<Card>();}/** * 玩家登录 */void login(){System.out.println("这里是登录界面：");    //通过try——catch捕获异常，限制输入ID为整数while(true){    try{    System.out.println("请输入第一个玩家的ID（限为数字）：");    String testid = console.next();    player1.id=Integer.parseInt(testid);    break;    }catch(NumberFormatException e){    System.out.println("请输入正确的ID!");     }    }        System.out.println("请输入第一个玩家的昵称：");        player1.name = console.next();            while(true){    try{    System.out.println("请输入第二个玩家的ID（限为数字）：");    String testid = console.next();    player2.id=Integer.parseInt(testid);    break;    }catch(NumberFormatException e){    System.out.println("请输入正确的ID!");     }    }        System.out.println("请输入第二个玩家的昵称：");        player2.name = console.next();}/** * 创建扑克牌 */void creatCards(){System.out.println("----------创建扑克牌-----------");for(int i=0;i<4;i++){for(int j=0;j<13;j++){AllCards.add(new Card(suits[i],figures[j]));}}System.out.println("---------创建成功----------");}/** * 两张扑克牌比较大小的方法(规则是：点数大的为大，点数相同比较花色，大小顺序为：黑桃>红心>梅花>方块), * 返回1代表ob1>ob2,返回-1代表ob1<ob2。 */int compare(Card cd1,Card cd2){int figure1 = 0;int figure2 = 0;//利用数组的下标来比较大小，下标大的就大for(int i=0;i<13;i++){//先获取其在数组中的下标if(cd1.figure == figures[i]){figure1=i;}if(cd2.figure == figures[i]){figure2=i;}}//比较大小if(figure1>figure2){return 1;}else if(figure1==figure2){for(int i=0;i<4;i++){if(cd1.suit == suits[i]){figure1=i;}if(cd2.suit == suits[i]){figure2=i;}}if(figure1>figure2){return 1;}else return -1;}else{return -1;}}/** * 遍历输出所有牌 */void forEach(){System.out.println("有以下扑克牌(通过for each访问)：");int i =1;for(Object obj:AllCards){Card cr = (Card) obj;System.out.print(cr.suit+"："+cr.figure+"   ");//每显示13个牌就换行if(i == 13 || i == 26 || i == 39){System.out.println();}i++;}System.out.println();}/** * 洗牌 */void Shuffle(){System.out.println("-----------开始洗牌---------------");for(int i=0;i<52;i++){int x=(int)(Math.random()*52);Card temp = AllCards.get(x);AllCards.set(x,AllCards.get(i));AllCards.set(i,temp);}System.out.println("-----------洗牌结束---------------");System.out.println("此时的牌顺序为：");forEach();}/** * 发牌 */void deal(){System.out.println("-----------------开始发牌--------------------");player1.cards.add(AllCards.get(0));player2.cards.add(AllCards.get(1));player1.cards.add(AllCards.get(2));player2.cards.add(AllCards.get(3));System.out.println("玩家"+player1.name+"的手牌为："+player1.cards.get(0).suit+":"+player1.cards.get(0).figure+"   和："+player1.cards.get(1).suit+":"+player1.cards.get(1).figure);System.out.println("玩家"+player2.name+"的手牌为："+player2.cards.get(0).suit+":"+player2.cards.get(0).figure+"   和："+player2.cards.get(1).suit+":"+player2.cards.get(1).figure);}/** * 比较大小，选出获胜玩家 */void fight(){System.out.println("比较大小：");int e = 0;//找出玩家1手里最大的牌int o = compare(player1.cards.get(0),player1.cards.get(1));//找出玩家2手里最大的牌int w = compare(player2.cards.get(0),player2.cards.get(1));if(o == 1&&w == 1){//玩家1,2用第一张牌比较大小e = compare(player1.cards.get(0),player2.cards.get(0));}else if(o == -1&& w == 1){e = compare(player1.cards.get(1),player2.cards.get(0));}else if(o == -1&& w == -1){e = compare(player1.cards.get(1),player2.cards.get(1));}else{e = compare(player1.cards.get(0),player2.cards.get(1));}if(e>0){System.out.println("玩家"+player1.name+"获胜！！");}else{System.out.println("玩家"+player2.name+"获胜！！");}}/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubTest t = new Test();t.login();t.creatCards();t.forEach();t.Shuffle();t.deal();t.fight();}}
