What happens when we assign a new subclass instance to a superclass variable identifier?

Specifically, what happens if I call subclass-only fields and methods from a superclass variable identifier?

e.g.

What's the output of Test?

I want to know the rationale behind the output, that's why I asked here rather than compiling it.

why don't you try and figure out the output yourself, and then run it and see if you're. right. If so, AWESOME!!!.

If you're wrong, try and figure out WHY you're wrong.

If you can't figure out why you're wrong, come back and ask us why the output is different from what you expect (and please tell us what you expected, what you got, and WHY you thought what you did).

THAT'S going to be the best way for you to learn.

(I don't want to circumvent anyone's learning experience, but...) Tim-Ting, your subclass declarations need to use the "extends" keyword. The way you've coded it, those classes are not subclassing SuperClass. Once you've done that, you can start exploring the question you raised.
 
Don't get me started about those stupid light bulbs.
