How do I get a list of instances of a particular class? Is there a way
to do this dynamically?

Also, what would be the way of dynamically creating an instance of a
class based on user input (ie a user wants to create a new instance of
the Stock class via shell input)?

I'm not sure if I have the wrong mindset here.

Thanks for any help
