Question

Write a Program in Java to input a number and check whether it is a Disarium Number or not.

Answer 1

import java.util.Scanner;

public class DisariumNumber {

   static boolean isDisarium(int number) {

       int sum = 0;

       for (int i = number, pos = (number + "").length( ); i != 0;  

            sum += Math.pow(i % 10, pos--), i /= 10);

       return sum == number;

   }

   

   public static void main(String[ ] args) {        

       System.out.print("Enter a number - ");

      int number = new Scanner(System.in).nextInt( );

       System.out.println((isDisarium(number) ? "A " : "Not a ") + "Disarium Number");

   }

}
