模拟斗地主发牌java学习

集合练习

1.只发牌 不排序

package 模拟斗地主;

import java.util.ArrayList;
import java.util.Collections;

public class PokerDemo {

	public static void main(String[] args) {
		//创建牌盒，也就是集合对象，用ArrayList集合实现
		ArrayList array=new ArrayList();
		
		//往牌盒里装盒
		
		
		//定义花色数组
		String []colors= {"♦","♣","♥","♠"};
		//定义点数数组
		String []numbers= {"2","3","4","5","6","7","8","9","10","J","Q","K","A"};
		for(String color:colors) {
			for(String number:numbers) {
				array.add(color+number);
			}
		}
		array.add("小王");
		array.add("大王");
		
		Collections.shuffle(array);
		
		//System.out.println(array);
		//发牌，也就是遍历集合
		ArrayList lqxArray=new ArrayList();
		ArrayList lyArray=new ArrayList();
		ArrayList fqyArray=new ArrayList();
		ArrayList dpArray=new ArrayList();
		
		for(int i=0;i=array.size()-3) {
				dpArray.add(poker);
			}else if(i%3==0) {
				lqxArray.add(poker);
			}else if(i%3==1) {
				lyArray.add(poker);
			}else if(i%3==2) {
				fqyArray.add(poker);
			}
		}
		
		lookPoker("林青霞", lqxArray);
		lookPoker("柳岩", lyArray);
		lookPoker("风清扬", fqyArray);
		lookPoker("底牌", dpArray);
		
	}
	
	public static void lookPoker(String name,ArrayList array) {
		System.out.println(name+"的牌是：");
		for(String poker:array) {
			System.out.print(poker+" ");
		}
	     System.out.println();
	}
	
	
}

2.发牌 并排序

package 模拟斗地主;

import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.TreeSet;

public class PokerDemo2 {

	public static void main(String[] args) {
		
		//创建HashMap，键是编号，值是牌
		HashMap hm=new HashMap();

		//创建ArrayList,存储编号
		ArrayListarray=new ArrayList();
		
		//定义花色数组
		String []colors= {"♦","♣","♥","♠"};
		//定义点数数组
	    String []numbers= {"3","4","5","6","7","8","9","10","J","Q","K","A","2"};
	    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);
	    
	    //洗牌
	    Collections.shuffle(array);
	    
	    TreeSet lqxSet=new TreeSet();
	    TreeSet lySet=new TreeSet();
	    TreeSet fqySet=new TreeSet();
	    TreeSet dpSet=new TreeSet();
	    
	    for(int i=0;i=array.size()-3) {
	    		dpSet.add(x);
	    	}else if(x%3==0) {
	    		lqxSet.add(x);
	    	}else if(x%3==1) {
	    		lySet.add(x);
	    	}
	    	else if(x%3==2) {
	    		fqySet.add(x);
	    	}
	    }
	    
	    lookPoker("林青霞", lqxSet, hm);
	    lookPoker("柳岩", lySet, hm);
	    lookPoker("风清扬", fqySet, hm);
	    lookPoker("底牌", dpSet, hm);
	}
	
	//定义方法拿牌
	public static void lookPoker(String name,TreeSetts,HashMaphm) {
		System.out.println(name+"的牌是：");
		for(Integer key:ts) {
			String poker=hm.get(key);
			System.out.print(poker+" ");
		}
		System.out.println();
	}
}
