RE: programing styles

["Mike Millson" <mgm@atsga.com>]

Isn't #2 better for garbage collection, since you are not creating and
destroying an object on each iteration of the loop? My understanding is that
the number of objects you create directly impacts speeds. The less objects,
the less garbage collection, and the faster the application. Given that, I
would think #2 is much more efficient and the style to use.

I would say the first one is - keep variable
declarations as local as possible - better
for garbage collection also, in most cases.

In your case, you gain nothing by declaring
them outside the for loop as you don't seem
to be using them outside the loop.
