综合练习—洗牌发牌Easy版

功能描述：
一.创建一副扑克牌，包括四种花色：黑桃，红桃，梅花，方片
十三中点数：2-10，J,Q,K,A，不考虑大小王

二.创建两名玩家
玩家至少要有ID，姓名，手牌等属性，手牌为扑克牌的集合

三.洗牌
将之前创建的“一副扑克牌”打乱顺序

四.发牌
将洗牌之后的扑克牌集合，从第一张开始，发给两名玩家，按照一人一张的方式，没人发两张

代码示例：

创建Poker类

package com.vishuo.www;/* * 创建扑克牌类，包含花色，点数属性 */public class Poker {      public String color; //扑克牌花色      public String points;//扑克牌点数      //有参构造方法      public Poker(String color,String points){          this.color = color;          this.points = points;      }}

创建玩家类

package com.vishuo.www;import java.util.HashSet;import java.util.Set;/* * 创建玩家类，包含ID，姓名，手牌属性，手牌可以存入HashSet中 */public class Players {    public int id;     //玩家id    public String name;//玩家姓名    /*     * 带有泛型Poker的Set的类型属性     *      */    public Set<Poker> handCards;//玩家手牌，使用集合框架Collection接口下面的Set子接口    /*     * 带参构造函数     *      */    public Players(int id,String name){        this.id = id;        this.name = name;        this.handCards = new HashSet<Poker>();//实例化，使用HashSet接口对玩家手牌进行实例化    }}

游戏类

package com.vishuo.www;import java.util.ArrayList;import java.util.Arrays;import java.util.Collections;import java.util.List;import java.util.Scanner;/* * 游戏部分 */public class Game {    public List<Poker> allcards;//全部扑克牌    public Game(){        this.allcards = new ArrayList<Poker>();//实例化    }    /*     * 创建一副扑克牌     */    public void setup(){        String color[] = {"黑桃","红桃","梅花","方片"};        String point[] = {"A","K","Q","J","10","9","8","7","6","5","4","3","2"};        for(int i=0;i<4;i++){            for(int j = 0;j<13;j++){                Poker poker = new Poker(color[i],point[j]);                allcards.add(poker);            }        }        System.out.println(allcards);    }    /*     * 通过for each方法访问集合元素     */    public void print(){        System.out.println("扑克牌有：");        for(Object obj:allcards){            Poker card = (Poker)obj;            System.out.println(card.color+card.points+",");        }    }    /*     * 创建玩家，输入ID和姓名     */    int id =0;    String name;    private Scanner input;    public int createPlayer(int num){        System.out.println("请输入第"+num+"位玩家的ID");        input = new Scanner(System.in);        //异常处理        try{            id=input.nextInt();        }catch(Exception e){            System.out.println("请输入一个整数ID");            return this.createPlayer(num);        }        System.out.println("请输入第"+num+"位玩家的姓名");        name = input.next();        return 0;    }    /*     * 发牌     */    public void deal(Players playernum){        Poker card = this.allcards.get(0);        playernum.handCards.add(card);        this.allcards.remove(card);        System.out.println("_______玩家"+playernum.name+"拿牌————————————");    }    /*     * 比较牌面大小     */    public Poker pkPoker(Poker a,Poker b){        ArrayList<String> color = new ArrayList<String>(Arrays.asList("黑桃","红桃","梅花","方片"));        ArrayList<String> point = new ArrayList<String>(Arrays.asList("A","K","Q","J","10","9","8","7","6","5","4","3","2"));         if(point.indexOf(a.points)<point.indexOf(b.points)){            return a;        }else if(point.indexOf(a.points)>point.indexOf(b.points)){            return b;        }else{            if(color.indexOf(a.color)>color.indexOf(b.color)){                return b;             }else{                return a;            }        }    }    /*     * main函数     */    public static void main(String args[]){        Game game = new Game();        System.out.println("————————————创建扑克牌——————————");        game.setup();        System.out.println("扑克牌创建成功！");        game.print();        System.out.println("开始洗牌");        Collections.shuffle(game.allcards);        System.out.println("洗牌结束");        System.out.println("创建玩家");        game.createPlayer(1);        Players player1 = new Players(game.id,game.name);        game.createPlayer(2);        Players player2 = new Players(game.id,game.name);        System.out.println("------欢迎玩家  " + player1.name + "和" + player2.name+"------");          System.out.println("------现在开始发牌------");         game.deal(player1);          game.deal(player2);          game.deal(player1);          game.deal(player2);        System.out.println("------发牌结束,游戏开始!------");          Poker card=new Poker("方片", "2");        for(Poker c:player1.handCards){            card = game.pkPoker(card, c);        }        System.out.println("玩家"+player1.name+"最大的手牌为:"+card.color+card.points);          Poker temp2 = new Poker("方片", "2");          for (Poker c: player2.handCards)          {              temp2 = game.pkPoker(temp2,c);          }          System.out.println("玩家"+player2.name+"最大的手牌为:"+temp2.color+temp2.points);          String winname;          if (game.pkPoker(card,temp2)==card)              winname = player1.name;          else winname = player2.name;          System.out.println("--------恭喜玩家"+winname+"获胜!--------");          System.out.println("--------玩家各自手牌为：--------");          System.out.print(player1.name+":");          for (Poker c: player1.handCards)          {              System.out.print("["+c.color+c.points+"] ");          }          System.out.println();          System.out.print(player2.name+":");          for (Poker c: player2.handCards)          {              System.out.print("["+c.color+c.points+"] ");          }      }}
