I'm waiting for your help
Again, it depends what you mean by "print".
All classes have a toString() method that you can override, and this is normally used to provide some sort of text-based representation of the instance.
I suspect (at least to start with) that's all you'll need; if you need anything more involved, you might consider a Printable interface (maybe with a print() method), and have all your list classes implement it. That way, your list can simply be a List<Printable>.
