Recursion - i want to print 1, 2, 3, 4, 5 and not 1, 2, 3, 4, 5, how to do?

Question

I'm a new to recursion. Can anyone tell me how to changes the method writeNums(int i) so it prints 1, 2, 3, 4, 5 and not 1, 2, 3, 4, 5, ?
Thanks.
public class Ex2writeNums
     public static void main(String[] args)
          writeNums(5);
     private static void writeNums(int i)
          if(i<0)
               throw new IllegalArgumentException("negative number");
          else if(i==0)
               //base case
               System.out.println();
          else
               // recursive case
               writeNums(i-1);
               System.out.print(i+", ");     
}

my code must be generic so i can use it for i=10 etc. So I can not write code like this:
     if(i != 5)System.out.print(i+", ");
else System.out.println(i);
Just add a second argument, limit, which specifies how high you must count. Your code becomes
     if(i != limit)System.out.print(i+", ");
        else System.out.println(i);There are many ways to do this. You now have at least three. Pick one.
