Niven/Harshad Number in JAVA

Niven/Harshad Number


A positive integer which is divisible by the sum of its digits, also called a Niven/Harshad number.


Example - 81 is divisible by 8+1= 9 . 81 is Niven Number.


 

Algorithm and Program below :-


Algorithm :-


  • Input a number to check for Niven Number

  • Store it in a new variable

  • Store the sum of its digit in a variable

  • Check if the number is divisible by the sum of digits without leaving remainder

  • If it is divisible print "It is Niven Number"

  • If not print "It is not Niven Number"


 

Program :-


import java.io.*; import java.util.*; class Niven {     public static void main(String args[])     {         Scanner in= new Scanner(System.in);         int n,p,rev,s=0;         System.out.println("Enter Number");         n= in.nextInt(); // Input number from user         p=n; // store the entered number in "p" variable         while(n>0)         {             rev=n%10; // extract last digit of the number             s=s+rev; // store the sum of digits             n=n/10; // extract all digit except the last         }         if(p%s==0) // if number is divisible by sum of digits leaving no remainder         {             System.out.println("It is Niven/Harshad Number : "+p);         }         else         {             System.out.println("It is not Niven/Harshad Number : "+p);         }     } // end of main method } // end of class

 

Note : The program is written in the easiest way possible so try understand it. If you face any problem in understanding this program than feel free to contact/comment. All the Best :)

Keep Learning :)
