Write a Java Program to find Armstrong number

Program

import java.util.*;
public class Main 
{
    public static void main(String[] args) 
    {
        int n, arg, sum = 0, r;
        Scanner s=new Scanner(System.in);
        System.out.println("Enter a number: ");
        n=s.nextInt(); // input value
        arg = n; 
        for (int i = 1; i < n; i++) 
        {
            while (n > 0) 
            {
            r = n % 10; 
            sum = sum + (r * r * r);
            n = n / 10;
            }
        }
        if (arg == sum) 
        {
            System.out.println("Given number is armstrong number: " + arg);
        } 
        else 
        {
            System.out.println("Given number is not armstrong number: " + arg);
        }
    }
}

Enter a number: 153
Given number is armstrong number: 153
