adding a collection to an arraylist collection

[ZeBula8]

for instance, i have a people class and a people collection.

i would like to create a phone collection which consists of
phone class and phone collection and then attach this to the
people class object.

so, in effect, i can call each people item and have the phone collection
as a property where i can iterate through this phone collection.

how can i make this happen?

thanks in advance.
