使用静态代码块生成一副扑克牌

public class PokePai {

    //定义一个静态集合
    public  static ArrayList<String> cards = new ArrayList<>();

    //静态代码块
    static {
        String[] sizes= {"2","3","4","5","6","7","8","9","10","J","Q","K","A"};
        String[] colors={"♥","♣","♠","♦"};
        //遍历点数
        for (int i = 0; i < sizes.length; i++) {
            //遍历花色
            for (int j = 0; j < colors.length; j++) {
                String card = sizes[i]+colors[j];
                cards.add(card);
            }
        }
        cards.add("大王牌");
        cards.add("小王牌");
    }

    public static void main(String[] args) {
        System.out.println("新牌：" + cards);
    }
}
