Question

I thought this would be relatively easy but running it, gives wrong result. It may be the initialization of the result variable but I cant seem to be able to modify the code such as to be correct. Here is my progress so far.

public class test 
{
   public static void main(String[] args)
   {
      int num1 = 10;
      int num2 = 4;

      int res = product(num1, num2);

      System.out.println(res); 
   }

   public static int product(int n1, int n2)
   {
      int result = 0 ;

      if (n2 > 0)
      {
          result = result + n1 ;
          product(n1,n2-1) ;
      }
         return result ;
   }
}

better solution
*here*

public static int product(int n1, int n2) 
           { 
              if (n2 > 1) 
              { 
                  n1 += product(n1,n2-1) ; 
              } 
                 return n1; 
           }
