In case it wasn't clear -- by "package the code" I just mean whether
you want to put it all in a main() method, or in static methods, or
build a proper Java class (with constructor and instance methods and
so forth) or what. In fact, just what you're saying here ....:

Hm. Why do you want this interface BasicTidy? Maybe you shouldn't
bother, but just define a class that provides only the functionality
you want. If it's an interface, it won't be useful unless you
have at least one class that implements it, and unless you think
that eventually you'll want more than one class that implements it,
what's the point of having a separately-defined interface? (Maybe
someone else will have a better answer for that.)

I'm not sure either, but I think you have the ideas straight anyway:

For example, if class ControlTidy extends Tidy and implements Runnable
(just an example, don't think this is how you should do things), when
you say

ControlTidy c = new ControlTidy();

you an object that's "really" a ControlTidy, but it could be used as
a ControlTidy, a Tidy, or a Runnable. Or, of course, an Object.

So c points to an object that's an instance of class ControlTidy,
and yet all of the following should evaluate to true:

c instanceof ControlTidy

c instanceof Tidy

c instanceof Runnable

Anyway to get back to your question -- if you define an interface
BasicTidy, then for an object to count as a BasicTidy, it has to
be an instance of a class that implements the BasicTidy interface.
