I had a discussion about with a colleague of mine, and I really need to clear things up.

First suggestion:
class Team{ ArrayList<Player> players; ... } class Player{ ...}Second suggestion:
class Team{ ArrayList<Player> players; ... } class Player{ Team team ...}My question is actually to know whether the objects of the class Player should know about the object Team that contains them.

I think the 1st is better. Method 2 is fine, but you have to be very careful when you have duplicated data, in that if it changes in one place it needs to change in all places

It depends on your application requirement, if you will require to get the Team details from Player then go with suggestion 1 otherwise suggestion 2.
