OOA question

[Stephen Cao]

Hi all:

I have a base class SurveyObject, and I derive two new classes
Question and Instruction.

I then create an
ArrayList<SurveyObject> soList = new ArrayList();
and add Instructions and Questions to the ArrayList.
Instruction i1 = new Instruction();
soList.Add(i1);
Question q1 = new Question();
soList.Add(q1);
Question q2 = new Question();
soList.Add(q2);

I have a form1 to handle Instructions and a form2 to handle Questions.

What is most elegant way to select the approrpriate form to display
the appropriate SurveyObject when I loop through the ArrayList of
SurveyObjects?

Thanks,
Stephen

The cleaner solution is to have separate collections for each form. Note: You
can't add multiple types to a generic arraylist, you can with a non-generic
arraylist though.
