import java.util.Collections;

public class DouDiZhu {
    public static void main(String[] args) {
        //建牌
        ArrayList<String> poker = new ArrayList<>();
        String[] colors = {"♠", "♦", "♣", "♥"};
        String[] numbers = {"2", "A", "K", "Q", "J", "10", "9", "8", "7", "6", "5", "4", "3"};
        poker.add("大王");
        poker.add("小王");
        for (String color : colors) {
            for (String number : numbers) {
                poker.add(color + number);
            }
        }
        //洗牌
        Collections.shuffle(poker);
        System.out.println(poker);
        //发牌
        ArrayList<String> p1 = new ArrayList<>();
        ArrayList<String> p2 = new ArrayList<>();
        ArrayList<String> p3 = new ArrayList<>();
        ArrayList<String> di = new ArrayList<>();
        for (int i = 0; i < poker.size(); i++) {
            String p = poker.get(i);
            if(i>=51){
                di.add(p);
            }else if (i%3==0){
                p1.add(p);
            }else if (i%3==1){
                p2.add(p);
            }else if (i%3==2){
                p3.add(p);
            }
        }
        //看牌
        System.out.println(p1);
        System.out.println(p2);
        System.out.println(p3);
        System.out.println(di);

    }
}
