Program Code

import java.util.*;

public class Armstrong

{

   public static void main(String[] args)

   {

   Scanner sc=new Scanner(System.in);

   System.out.print("Enter any number: ");

   int num=sc.nextInt();

   int sum=0,dig=0,rem,num1=num;

   int orgNum=num;

   while(num1!=0) //counting no of digits in number

   {

       num1/=10;

       dig++;

   }

   int flag=dig;

   for(int i=0;i<flag;i++)

   {

      rem=num%10;

      sum+=Math.pow(rem,dig);

      num=num/10;

   }

   if(orgNum==sum)

       System.out.println(orgNum+" is Armstrong number!");

   else

       System.out.println(orgNum+ " is not a Armstrong number!");

   }

}

Output

Enter any number: 407

407 is Armstrong number!
