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
