Thread: Java class probelm

Hi I have this little issue with my program.

I have a class called Library which has a one to one relation with a class called collection and class collection has one to many relation with a class called Holding which is an array list. Also class library has a one to one relation with a class called Member. What I would like to know and which I don't know how to do is, how can I modify thing inside the array list of books through the member class.

Any help will be very much appreciated.

Thanks In Advance

Hey spikestar and lily11022,

First of all, welcome to the forum.

Now to the problem: spike, your whole structure is bad. A library class that's one to one relation with a collection class? I think you need to restart and think it out more clear and better, and because of the bad structure(imho) it's hard to understand how to do things in it.

Lets approach this problem different. Post your assignment and the code you already have. We can help you from there.

It would help if you described what this application is trying to achieve - what does it need to do, how would it be used? This way we can discuss an architecture that supports the requirements.
