There is no way "around". The whole idea of "final" is to prevent

And is, in my opinion, idiotic. If there's a good reason there might
be a problem, it should be documented rather than taking the 'punt'
way out and making it final.
Why don't you create proxy class which will wrap around Boolean and
encapsulate your special behavior in this class letting Boolean
object do the rest?
Yes, I could do that, but I really don't want to because it's ugly
and gross, and if my object gets passed to a regular boolean with
equals(), it might fail (not sure how it would react).

OK, I'm a little annoyed here because I find the whole concept of
'final' to be ridiculous.
I would like to subclass Boolean so that I can initialize it
(class method) with a short string (valueOf:"t" instead of
valueOf:"f") and also to return "t" and "f" for toString (or some
other method like toShortString()).
Unfortunately, java.lang.Boolean is marked as final. Is there any
way to get around that?
To give a little background, I would like to have a custom
WebObjects type where I can declare the factory method to create
the instance, and the method to call to get back the string
instance. I want to make it a single character so that I can use
a string field with length=1 instead of length=5 (saving a lot of
space).
Oh, and yet another reason I want categories from Objective-C in
Java...
Thanks,
Ken
