How to print?

Hi,
im pretty new to java. Im attending a programming class at a college in norway. I have only been programing for 3 months.

My question is, how can i for example print all items or a selected item from the games archive(so i get it in a new window with the info requested when choosing print)?
I have tried some codes with println, but only got to print the key/id that the object has in the archive.
I hope anyone here can help me and show me how the print code should look like.
I have for your information as you maybe can see, created classes for the objects and the archives before i created the main class RentalArchive.

kind regards
Alexander
