Well, I have to crawl before I can walk, and walk before I can run. I
can see now that's not necessary to use the String.valueOf because I'm
writing a String so it's just redundant to add the method. But from my
original post, please recall that I stated I was re-using my old code.
What I did not mention was that in my original code I was writing an
integer--not a String as is in this case--to a file. So in that case I
needed String.valueOf to grab the integer and convert it to a String.
So on the surface, yes, it looked clumsy but only because it was
re-used code and I wasn't paying such close attention to that part. In
any case, thanks for pointing it out to me. It's the little stuff I
miss that will help me write better code as I learn (and am taught).
Thanks!
