Using Constructor Check a Number for Niven Number

If a number is completely divisible by sum of the digits of the number, it is known as Niven number.

import java.util.*;

class Ab

{

 int n,m;

Ab(int x)

{

 n=x;

}

public void show()

{

m= sumOfDigits (n);

if(n%m==0)

System.out.println(“Niven Number:”);

else

System.out.println(“Not Niven Number:”);

}

private int sumOfDigits(int n)

{

 int c=0,i;

for(i=n;i>0;i=i/10)

{

c=c+i%10;

}

return c;

}

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

int n;

System.out.println("Enter the number:");

n=sc.nextInt();

Ab obj=new Ab(n);

obj.show();

}

}
