java模拟斗地主案例

 利用HashMap和ArrayList，模拟斗地主洗牌，发牌，看牌，案例。

package com.gaojixifa;

import java.util.*;

public class Xifaplus {
    public static void main(String[] args) {
        HashMap<Integer,String> hm = new HashMap<Integer, String>();//利用索引找到对应的牌
        ArrayList<Integer> array = new ArrayList<Integer>();//牌的索引
        String[] colors = {"♦","♣","♥","♠"};
        String[] numbers ={"2","3","4","5","6","7","8","9","10","J","Q","K","A"};
        int index = 0;
        for(String number : numbers){
            for(String color : colors){
                hm.put(index,color+number);
                array.add(index);
                index++;
            }
        }
        hm.put(index,"小王");
        array.add(index);
        index++;
        hm.put(index,"大王");
        array.add(index);
        Collections.shuffle(array);
        TreeSet<Integer> lqxset = new TreeSet<Integer>();
        TreeSet<Integer> lyset = new TreeSet<Integer>();
        TreeSet<Integer> fqyset = new TreeSet<Integer>();
        TreeSet<Integer> dpset = new TreeSet<Integer>();
        for(int i=0;i<array.size();i++){
            int x = array.get(i);
            if(i>=array.size()-3){
                dpset.add(x);
            }else if(i%3==0){
                lqxset.add(x);
            }else if(i%3==1){
                lyset.add(x);
            }else if(i%3==2){
                fqyset.add(x);
            }
        }
        Lookpocker("林青霞",lqxset,hm);
        Lookpocker("柳岩",lyset,hm);
        Lookpocker("风清扬",fqyset,hm);
        Lookpocker("底牌",dpset,hm);
    }
    //下面是看牌的方法
    public static void Lookpocker(String name,TreeSet<Integer> ts,HashMap<Integer,String> hm){
        System.out.println(name+"的牌是：");
        for(Integer key : ts){
            String pocker = hm.get(key);
            System.out.print(pocker+" ");
        }
        System.out.println();
    }
}

运行的结果：

林青霞的牌是：
♣2 ♣4 ♠6 ♦7 ♥7 ♠7 ♣8 ♠10 ♦J ♣Q ♠Q ♦K ♥K ♠K ♣A ♥A 大王 
柳岩的牌是：
♦3 ♥3 ♠3 ♥4 ♠4 ♣5 ♦6 ♣6 ♥8 ♦9 ♣9 ♥9 ♦10 ♦Q ♦A ♠A 小王 
风清扬的牌是：
♦2 ♠2 ♣3 ♦4 ♦5 ♠5 ♥6 ♦8 ♠8 ♠9 ♣10 ♥10 ♣J ♥J ♠J ♥Q ♣K 
底牌的牌是：
♥2 ♥5 ♣7
