#JavaSe# 在只有扑克牌颜色数组和数字数组的情况下，合成扑克牌，并且完成抽牌操作

定义一个扑克牌类

public class Card {
    private String[] point={"A","2","3","4","5","6","7","8","9","10","J","Q","K",};
    private String[] color={"黑桃","红桃","梅花","方片"};
    
    public String[] getPoint() {
        return point;
    }

    public void setPoint(String[] point) {
        this.point = point;
    }

    public String[] getColor() {
        return color;
    }

    public void setColor(String[] color) {
        this.color = color;
    }
}

定义测试类

import java.util.ArrayList;
import java.util.Random;
import java.util.Scanner;

/**
 * 扑克牌 list为牌堆，listCard为抽牌人现有的牌
 */
public class Test {
    public static void main(String[] args) {
        Random r = new Random();
        ArrayList list = new ArrayList();
        Card card = new Card();
        String point[]=card.getPoint();
        String color[]=card.getColor();
        for (int i = 0; i <4 ; i++) { 
            for (int j = 0; j <13 ; j++) {
                list.add(color[i]+point[j]);  //将扑克牌的花色和数字组合成52张扑克牌
            }
        }
        Scanner scanner = new Scanner(System.in);
        int random = scanner.nextInt();  //键盘输入要抽几张牌
        ArrayList cardList = new ArrayList();
        System.out.println("随机"+random+"张牌：");
        if(random<=52 && random>0){//防止抽过多的牌

        for (int i = 0; i < random; i++) {
            int index = r.nextInt(52-i);
            cardList.add(list.remove(index));
        }
        System.out.println(cardList);
        System.out.println("此时牌堆还剩："+list); //检测牌堆
    }
        else System.out.println("超过范围，无法获取");
    }
}
