How to use a .class file with .java files

Question

I am pretty green for java (I program in C / C ++) and I still haven't figured out how it all works.

I am not trying to ask someone to do their homework, I am just confused by some basic java materials. I have a task that wants me to create a maze. The destination comes with some files that were previously implemented and theoretically work. The folder gives me some .java files and some .class files. I opened the .java files, and most of them are interfaces without real code, so I assume this is meat in these .class files. My question is: how do I interact with these .class files? I need to do something like import myClass; if i have myClass.class file?

I tried to import the file directory in which these files are contained (via Eclipse), but it seems that the .class files are not showing. I assume it is being processed in the background?

Here is a link to the task http://www.ics.uci.edu/~goodrich/teach/ics23/LabManual/Dark/

Here's a zip file with all the .java and .class files http://www.ics.uci.edu/~goodrich/teach/ics23/LabManual/Dark/Dark.zip

Thanks in advance!
