for循环案例之判断是否为水仙花数

import java.util.Scanner;

public class Test3 {

public static void main(String[] args) {

System.out.println("请输入一个三位数");

Scanner scanner=new Scanner(System.in);

int input=scanner.nextInt();

if (input<=990||input>=100){

int a=input%10;

int b=input/10%10;

int c=input/100;

if (a*a*a+b*b*b+c*c*c==input){

System.out.println("是水仙花数");

}else {

System.out.println("不是水仙花数");

}

}else {

System.out.println("请重新输入");

}

}
