Answer 1

Answer:// Java program to compute  

// sum of digits in number.  

import java.io.*;  

 

class GFG {  

     

   /* Function to get sum of digits */

   static int getSum(int n)  

   {      

       int sum = 0;  

         

       while (n != 0)  

       {  

           sum = sum + n % 10;  

           n = n/10;  

       }  

     

   return sum;  

   }  

 

   // Driver program  

   public static void main(String[] args)  

   {

while(n>0){

sum += n%10;

n/=10;

}

System.out.println("The sum is = "+sum);

}
