RE: Instantiation question

["Stone, Brad V (TC)" <bvstone@xxxxxxxxxxxxxx>]

I'll let others answer you question, but I'd like to expand on your
question.

Why do you need to say:

Student show = new Student();

Why not just:

show = new Student();

Is there a case where you would want to do something like:

Student show = new Principal();
or
Principal show = new Student();

Maybe the answer to your original question will answer mine.  :)  I've
always thought that this type of declaration was a bit redundant.
