Write a program to find the armstrong number using Java

 Armstrong number is a number that is equal to the sum of cubes of its digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers.

import java.util.Scanner;

public class ArmsrongNumber {

public static void main(String[] args) {

int no, no_backup, rem, sum = 0;

Scanner sc = new Scanner(System.in);

System.out.println("Enter number to find its armstrong or not : ");

no = sc.nextInt();

no_backup = no;

while (no > 0) {

rem = no % 10;

sum = sum + rem * rem * rem;

no = no / 10;

}

if (no_backup == sum) {

System.out.println("Armstrong number");

} else {

System.out.println("Not armstrong number.");

}

}

}
