JD:

Can you tell me what it's buying you to hide main?  Knowing the
history of inner classes and the forced use of them in Java, I still
haven't come up with any compelling reasons to use them (at least not
ones the weigh out against the need for others to maintain code).

It's one of those things that come up on a regular basis here (the
"why would I use inner classes", and so far the common answer is
"'cause I can" <g>).

If you see something that looks like an opinion up there,
it's mine and mine alone.

Mail sent to me from the newsgroups won't bounce but will
be ignored.  If I have time, I'll respond, but you  have
a better chance if you confine your posts to the newsgroups
