I have a deadline in a few hours and can't figure out what I'm doing wrong.

Answer 1

Thank you so much! That actually worked.

Answer 2

@Serena Yvonne Added the code now.

Answer 3

@Serena That code is missing the TestStatistics class though. I can't run it if I just add that code to main class.

Answer 4

Ok, I think I understand what you did. So I need to completely remove the Main class I created. It's useless because there's already a main method in the TestStatistics class?
I was just trying to wrap my head around the exercise by using methods done in previous labs and they used separate Main class with main method to call other methods.
