java拿火柴小游戏

以下是一个Java实现的拿火柴小游戏的示例代码：

import java.util.Scanner;

public class MatchGame {
    public static void main(String[] args) {
        int matches = 21;
        int currentPlayer = 1;

        Scanner scanner = new Scanner(System.in);

        while (matches > 0) {
            System.out.println("当前火柴数量：" + matches);
            System.out.println("玩家" + currentPlayer + "请取走1-4根火柴：");
            int numMatches = scanner.nextInt();

            if (numMatches < 1 || numMatches > 4 || numMatches > matches) {
                System.out.println("无效的选项，请重新输入！");
                continue;
            }

            matches -= numMatches;

            if (matches == 0) {
                System.out.println("玩家" + currentPlayer + "输了！");
                break;
            }

            currentPlayer = (currentPlayer == 1) ? 2 : 1;
        }

        scanner.close();
    }
}
