Given a number, we have to check that the entered number is Harshad Number or not.

A number is said to be Harshad Number if and only if the sum of entered number completely divides the entered number (into 10 bases).

Example:

Input: 18
Sum = 1 + 8
Now, 18 are dividing by 9 completely.

## Program to check whether the given number is Harshad Number or not in Java

package IncludeHelp;

import java.util.Scanner;

{
public static void main(String args[])
{
// create object of the class.
Scanner sc = new Scanner(System.in);

// enter number here.
System.out.print("Enter the number to check : ");
int n = sc.nextInt();
int c = n, d, sum = 0;

//finding sum of digits
while(c>0)
{
d = c%10;
sum = sum + d;
c = c/10;
}

if(n%sum == 0)
else
System.out.println(n+" is not a Harshad Number.");
}
}

Output

First run:
Enter the number to check : 442
442 is not a Harshad Number.

Second run:
Enter the number to check : 18
