步骤 准备牌 洗牌 发牌 排序 看牌

一.代码实现

public class DouDiZhu {
          
   
    public static void main(String[] args) {
          
   
        //1.准备牌
        //定义一个存储54张牌的集合ArrayList，泛型使用字符串
        ArrayList<String> poker=new ArrayList<>();
        //定义两个集合分别存储花色和序号
        String[] colors={
          
   "♠","♥","♦","♣"};
        String[] numbers={
          
   "2","A","K","Q","J","10","9","8","7","6","5","4","3"};
        //将大王小王添加到集合里
        poker.add("大王");
        poker.add("小王");
        //循环嵌套遍历两个数组，组装53张牌
        //使用增强for循环
        for(String number:numbers){
          
   
            for (String color : colors) {
          
   
               // System.out.println(color+number);
                poker.add(color+number);
            }
        }
        System.out.println(poker);
        //2.洗牌
        //使用集合的工具类collections中的方法
        Collections.shuffle(poker);
        //3.发牌
        //定义4个集合存储玩家牌和底牌
        ArrayList<String> player01=new ArrayList<>();
        ArrayList<String> player02=new ArrayList<>();
        ArrayList<String> player03=new ArrayList<>();
        ArrayList<String> diPai=new ArrayList<>();
        for(int i=0;i<poker.size();i++){
          
   
            String p=poker.get(i);
            if(i>=51){
          
   
            diPai.add(p);}
            else if(i%3==0){
          
   
                    player01.add(p);
            }else if(i%3==1){
          
   
                player02.add(p);
            }else if(i%3==2){
          
   
                player03.add(p);
            }
        }
        //4.排序
        Collection.sort(player01);
        Collection.sort(player02);
        Collection.sort(player03);
        Collection.sort(diPai);
        //5.看牌
        System.out.print("张三的牌"+player01);
        System.out.println();
        System.out.print("李四的牌"+player02);
        System.out.println();
        System.out.print("王五的牌"+player03);
        System.out.println();
        System.out.print("底牌"+diPai);

    }
}
