Iterating multiple collections

[x-ice]

What is the purpose of this iteration?

I need to execute the print method of each object in both collections in a specific order. Like this:

Collection1[1].print()
Collection2[1].print()
Collection1[2].print()
Collection2[2].print()
Collection1[3].print()
Collection2[3].print()
Collection1[4].print()
Collection2[4].print()

and so on...

To be more specific

I have a dating system (uni coursework) that is meant to match male and female customers. I am doing this the simple (gaining slightly lower marks) way.

I have two collections :- maleCust and femaleCust, both contain Customer objects.

I want to match the first male with the first female found in both collections, and so on... I think an iterator would be perfect for this.
