Ben Aroia

heres a program that incrypts files. comlpeate with 'regestration',
I/O file writing, and a help menu with a scroll pane. try it out and
tell me how u like it in a posting! no e-mail please!

Don't like it. Terrible variable naming, indentation
and style in general. From an architechtural point
of view it is even worse, mixing model logic, GUI and
I/O all in one class.

And if you are to post programs in the future, do so
by a link.

...try it out and tell me how u like it in a posting!

A couple of points/tips Ben.

It is best to put code like this (1300 lines)
on a web site and then give a link to the groups
and invite people to download it.

Posting the code to a group as you did means..

a) _Everybody_ downloads it, including those with
no interest in encryption (like myself, for example)

b) The lines break. Try copy/pasting the code you
posted back into your IDE and compiling it. Just
out of curiousity, I did that, 59 errors.

As a side note, it might also help if you
cast an eye over how other Java programmers
name classes, attributes and methods.

Your naming system would confuse most Java programmers.
Take, for example, 'joshFinalUnit16'.

Most Java programmers would guess that to be
either an attribute or method (though poorly named,
even then) whereas if it is a class, it would be
'JoshFinalUnit16'.

Of course, something like 'Encryptor' would
have been better still ..though that is
getting dangerously close to a verb, whereas
class names should (in a perfect world) be
nouns.

Now, if you are indeed _serious_ about getting
other people to look at it, I recommend you
save them the trouble of fixing the wrapped lines
by promptly uploading your source to a free
site and getting back to us.

Back to you.

I think your utility class could do with a lookup table.
