Working With Test My Code (TMC) plugin. Trying to run a class (Name.java) and and it throws me the "Choose main class" Window

I tried selecting that class, "Name.java" from the menu. Then I searched a bit and found "Name.class" and tried selecting that. Neither was allowed a selection. 

In frustration I went through the entire project and tried to select anything. No luck. 

I tried running the program with a temporary configuration using Control + Shift + f10. That did nothing. I tried finding a menu selection like "Run Temporary Configuration" or something similar to no avail. 

I'm really not sure how to proceed. I would like to be able to run these projects and see their output! What do I need to do? 

Thank you in advance of your help! I realize this might be a fairly simple question, I definitely don't mean to be thick, or to upset anyone who is a pro. I have spent a good deal of time looking for the solution elsewhere, but I can't turn it up. Maybe I'm looking for the wrong thing :(
