This updated code is basically working the way the professor asked for. In the Attendee1.java file is where most of the work is done. I thought using enums for the list of labs, restaurants, and presentations was a decent idea so it will be easy to change for the user in the future. I also had enums for the transportation options when going to the lab as well as the registration cost. If you have a different way of doing any of that then feel free to change it. Everything else about the code should be fairly simple for you to understand. If you have any questions then I can clear it up quickly. Nothing I did is set in stone I just wanted to give you my ideas for the assignment.
