Answer 2

Program of Niven or not

Output:

Enter the number:

450

number is niven

Explanation:

import java.util.*; // Import Package

public class Main // main class

{

public static void main(String[] args)  // main method

{

 int sum =0; // variable declaration

Scanner sc2 = new Scanner(System.in); // creating the object of scanner

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

       int n= sc2.nextInt(); // taking input

       int n1=n; // assigning this to another number

       while(n1>0) // iterating the loop

       {

           int rem=n1%10; // calculating reminder

             sum=sum+rem; // finding the sum of digit

           n1=n1/10; // obtain quotient

       }

       if(n%sum==0) // checking the condition

       System.out.println("number is niven");

       else

    System.out.println(" number is not niven");

}

}

Following are the description of program

• Creating the instance of scanner class sc2 for taking the user input in the variable "n" .

• The nextInt() method is used for taking input in the integer type .

• After that iterating the while loop to calculating the sum of digit of number of variable "n".

• The "sum" variable is used for finding the sum of digit .

• Finally  the if condition is used for check number is niven or not.
