## ♣准备牌

``````//定义一个存储54张牌的ArrayList集合,泛型使用String
ArrayList<String> poker = new ArrayList<>();
//定义两个数组,一个数组存储牌的花色,一个数组存储牌的序号
String[] colors = {"♠","♥","♣","♦"};
String[] numbers = {"2","A","K","Q","J","10","9","8","7","6","5","4","3"};
//先把大王和小王存储到poker集合中
poker.add("大王");
poker.add("小王");
//循环嵌套遍历两个数组,组装52张牌
for(String number : numbers){
for (String color : colors) {
//System.out.println(color+number);
//把组装好的牌存储到poker集合中
poker.add(color+number);
}
}

## ♠️洗牌

## ♥️发牌
