java数组猜数字游戏

以下是Java数组猜数字游戏的示例代码：

import java.util.Scanner;

public class GuessNumber {
    public static void main(String[] args) {
        int[] answer = {1, 2, 3, 4}; // 答案数组
        int[] guess = new int[4]; // 玩家猜测的数组
        Scanner scanner = new Scanner(System.in);

        // 循环猜测，直到猜对为止
        while (true) {
            // 提示玩家输入猜测的数字
            System.out.println("请输入4个数字，用空格分隔：");
            for (int i = 0; i < 4; i++) {
                guess[i] = scanner.nextInt();
            }

            // 检查猜测的数字是否正确
            int a = 0, b = 0;
            for (int i = 0; i < 4; i++) {
                if (guess[i] == answer[i]) {
                    a++;
                } else {
                    for (int j = 0; j < 4; j++) {
                        if (guess[i] == answer[j]) {
                            b++;
                            break;
                        }
                    }
                }
            }

            // 输出猜测结果
            System.out.println(a + "A" + b + "B");

            // 如果猜对了，退出循环
            if (a == 4) {
                System.out.println("恭喜你猜对了！");
                break;
            }
        }
    }
}
