Help with Class!

Hello there everyone. I need some help here, I have to make a class/es for a library for loan management, where everytime a person loan a book it checks or verify the user against the existing users database and checks for his/her penalties or fees if it has one. and if not lets him/her loan a book. can Anybody help me with this.

Thanks
Joel.

You dont need halp making a class you need help designing the entire projecet.

2 x ways to this, either you travers an table that holds all members which have penalties or fees.

Or you create an SQL query which get's all the memeber data in one table and check that table.
