How to find Armstrong Number in java Using by Scanner

• Since 153 = 1*1*1 + 5*5*5 + 3*3*3. So 153 is an Armstrong number
• Since 12 is not equal to 1*1*1+2*2*2. So 12 is not an Armstrong number

//Here start Example for armstronNumber have or not

 

// Using by Scanner 

 import java.util.Scanner;

public class ArmstrongNumber
{
    public static void main(String args[])
    {

        Scanner scan = new Scanner(System.in);
  
        System.out.print("Enter any Positive Number : ");
        n = scan.nextInt();
  
        nu = n;
  
        while(nu != 0)
        {
            rem = nu%10;
            num = num + rem*rem*rem;
            nu = nu/10;
        }
        if(num == n)
        {
            System.out.print("Armstrong Number");
        }
