Hello, I'm having some issues with my code and if anyone could help, that'd be great.

This is the code I'm working with, it's in 3 separate class files and there are 3 data files at the bottom:

This is one of the errors I'm getting and I'm not really sure how to fix it. Is it just wanting me to change the names?

The other problem I'm having is in StudentListManager.java. I'm supposed to display the amount of students in the ArrayList and I'm not sure how to do so.

Thank you for any help, I appreciate it. Please let me know if there's any information I need to add.
