Question on OOP-4 Requirements

For OOP-4 (Lookup) ...

1. Is it OK to simply use 1,2,3, ... 12 as the serial numbers? Seems like doing so would keep nitpicker life moderately simpler.

2. The assignment only asks for a string of info about a particular item. My first thought is to simply use a long string of descriptive text for each item. (eg - "This is a book called blah, written by blah, which costs blah to rent , etc.") But this approach doesn't seem in spirit with the assignment purpose to learn all about polymorphism. There would not be anything really different from a video item and a furniture item.

So, I'm guessing I should really define a variety of relevant fields for each class, and build the text string from a particular instance of field values. Is this second approach more in keeping with the assignment goal?

Thank you very much.

You can use anything you want for the serial number(s).

Your second approach sounds more like what we are looking for.
