用Java实现扑克牌洗牌

Posted 2022-11-21 wukongk

Java已经忘了差不多了，最近又需要重新捡起Java。

对于一副扑克牌共有54张，扑克牌洗牌就是将这54张牌没有规律的输出出来，

用ArrayList实现，本质是54个数的随机输出，穿了身衣服，输出出来就好看多了

public class Poker 
	public static String poker(int num) 
		String str = "";
		String[] huase = "红桃","黑桃","梅花","方块";
		String[] number = "A","2","3","4","5","6","7","8","9","10","J","Q","K";
		if(num/4 > 12) 
			if(num%4 == 0) 
				str += "小鬼";
			 else if(num%4 == 1) 
				str += "大鬼";
			
		 else 
			str += huase[num%4] + number[num/4] ;
		
		return str;
	

public class Client 

	public static void main(String[] args) 
		// 定义变量
		ArrayList list = new ArrayList();
		Random random = new Random();
		Poker poker = new Poker();
		int i = 0;
		
		// 向数组中增加数字
		for(i=0;i<54;i++) 
			list.add(poker.poker(i));
		
		
		// 随机输出数组中的每个数字
		int length = list.size();
		for(i=0;i<length;i++) 
			//随机生成数组下标
			int num = random.nextInt(list.size());
			//取出数字
			System.out.println(list.get(num));
			//将数字从数组中移除
			list.remove(num);
		
	

看起来舒服多了
