3.31 Make Classes Final Where Possible

Juppies 2 by Dr Heinz M. Kabutz

We should probably clean up our classes a bit before closing our third session. One thing I like to do is to make as many classes final as I can. That limits how another programmer might subclass it in a way I did not expect. I am quite happy to change that to be non-final if someone needs to subclass it, but then I would like to be part of the discussion as to how and why they want to do it.

There is a recommended order for all our modifiers, which I write about in my newsletter 293.
