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<String> array=new ArrayList<String>();
		
		//往牌盒里装盒
		/**
		 * ♦2 ♦3    
		 * ♣2 ♣3
		 * ♠2 
		 * 大王，小王
		 */
		
		//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<String> lqxArray=new ArrayList<String>();
		ArrayList<String> lyArray=new ArrayList<String>();
		ArrayList<String> fqyArray=new ArrayList<String>();
		ArrayList<String> dpArray=new ArrayList<String>();
		
		for(int i=0;i<array.size();i++) {
    
    
			String poker=array.get(i);
			
			if(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<String> 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<Integer,String> hm=new HashMap<Integer, String>();

		//创建ArrayList,存储编号
		ArrayList<Integer>array=new ArrayList<Integer>();
		
		//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<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(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,TreeSet<Integer>ts,HashMap<Integer,String>hm) {
    
    
		System.out.println(name+"的牌是：");
		for(Integer key:ts) {
    
    
			String poker=hm.get(key);
			System.out.print(poker+" ");
		}
		System.out.println();
	}
}
