Unless you will claim that there is only two possible
states non-OO and OO, then something can be more or less
OO than something else.

Calling something nonsense is not a very convincing argument.

Try instead of writing an application able to add two integers
and display the result in Swing, Struts 1.x and JSF - and count
number of occurrences of inheritance, polymorphism and encapsulation
for each compare dto number of lines written.

I think you will find that Swing has a lot of OO features, while
Struts 1.x and JSF are more multi-paradigm oriented, which means
less OO.

But that is exactly what you would want to discuss in an OO course.

Don't need that for a basic Swing app.

There will be a bit of black magic with that, but it is nothing compared
to CSS.

That is very OOish.

You can do basic Swing with a modest number of classes.
