用java写一个猜牌游戏

这是一个简单的猜牌游戏，使用Java语言编写。游戏规则是：程序会随机生成一张扑克牌，玩家需要猜测这张牌的花色和点数，如果猜对了就赢得胜利，否则就失败。

代码如下：

import java.util.Scanner;

public class GuessCardGame {

    public static void main(String[] args) {
        String[] suits = {"Spades", "Hearts", "Diamonds", "Clubs"};
        String[] ranks = {"Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King"};
        int suitIndex = (int) (Math.random() * 4);
        int rankIndex = (int) (Math.random() * 13);
        String card = ranks[rankIndex] + " of " + suits[suitIndex];
        System.out.println("I'm thinking of a card. Can you guess what it is?");
        Scanner scanner = new Scanner(System.in);
        String guess = scanner.nextLine();
        if (guess.equalsIgnoreCase(card)) {
            System.out.println("Congratulations! You guessed the card.");
        } else {
            System.out.println("Sorry, the card was " + card + ".");
        }
    }

}

运行程序后，会输出一句话提示玩家开始猜牌。玩家需要在控制台输入自己的猜测，程序会将猜测与随机生成的扑克牌进行比较，如果猜对了就输出胜利的信息，否则输出失败的信息。
