Write a program to input an integer and check whether it is Harshad or Niven number or not. A number is said to be Harshad if it is divisible by the sum of the digits of that number, example 126 and 1729.

Solution:

Language used: Java

import java.util.*;

public class NivenNo

{

static void main()

{

Scanner sc=new Scanner(System.in);

int d,s=0,n,t;

System.out.println("Enter an integer:");

n=sc.nextInt();

t=n;

while(t!=0)

{

d=t%10;

s=s+d;

t=t/10;

}

if(n%s==0)

System.out.println("Harshad Number");

else

System.out.println("Not a Harshad Number");

}

}
