Hi all. It's basically my first time i'm working on Java and I am already stuck! I have to
implement methods & decide on an
appropriate type of collection from the java.util package in, which individual bank accounts will be stored. I also have to
declare a field to refer my collection.
I also have to
create a field to keep track of the next available account number.
So far I know that
all field in the classes should be Private and any
method I add to the Bank class must also be private.
I've created my other classes so there fine, it's just this i'm stuck on.
Thanks in advance and don't worry it isn't a piece of coursework so i'm not cheating or anything ridiculous like that because at the end of the day I won't learn anything!
It's a project my cousin has sent me from his previous year at uni. I'm still at college and want to do Computer Science so I want to learn before I do it next year if you know what I mean.
Thank you again.
