java 递归实现水仙花数

Sure, Java递归实现水仙花数的代码如下：

import java.util.Scanner;

public class NarcissisticNumber {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入数字n：");
        int n = input.nextInt();
        for (int i = 1; i <= n; i++) {
            if (isNarcissistic(i)) {
                System.out.println(i + "是水仙花数");
            }
        }
    }

    public static boolean isNarcissistic(int num) {
        String str = String.valueOf(num);
        int n = str.length();
        int sum = 0;
        for (int i = 0; i < n; i++) {
            int digit = str.charAt(i) - '0';
            sum += Math.pow(digit, n);
        }
        return sum == num;
    }
}

请问你还有什么问题吗？
