data structure question

[veronica86]

hello,

I am designing an ASP.NET web application and have 1 class (PurchaseOrder) that contains another class (Item) as an attribute. (Using aggregation)

The Item class has 2 attributes (name & quantity). I am trying to find the best data structure to hold many instances of Item within the PurchaseOrder.

Each item has 2 attributes. I was thinking an ArrayList. Would I need a 2 dimensional ArrayList, if that exists?

thanks for any advice!!

Depends on how you want to do it, if you want to call a new PO everytime you need one then you wouldn't need the array. If you call a global PO then you could use an arraylist (which you could stick an arrayinto) If you use an arraylist you'll need to keep track of which PO is which.
