java写从一副牌中不放回抽取两张牌

以下是一种实现方式：

import java.util.ArrayList;
import java.util.Collections;

public class DrawCards {
    public static void main(String[] args) {
        // 创建一副牌
        ArrayList<String> cards = new ArrayList<>();
        String[] suits = {"♠", "♥", "♦", "♣"};
        String[] ranks = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};
        for (String suit : suits) {
            for (String rank : ranks) {
                cards.add(rank + suit);
            }
        }

        // 洗牌
        Collections.shuffle(cards);

        // 抽取两张牌
        String card1 = cards.remove(0);
        String card2 = cards.remove(0);
        System.out.println("抽到的两张牌为：" + card1 + " 和 " + card2);
    }
}

运行结果示例：

抽到的两张牌为：7♦ 和 6♠
