IntelliJ opens an unrelated .java when I run code.
This is annoying, and I don't know how to fix it. I am trying to run code. I even have my cursor placed in this program. However, when I decide to run the code, an unsolicited .java files comes up. Like, I didn't even ask that program to appear. How can I stop this?

How to ensure that the hashset of Solutions behaves correctly?
I'm failing the 2nd last requirement, but I am not sure why. The task description says that the main method isn't tested, so I don't know how to go about passing this test. I'm getting the correct answer as far as I can tell. I'm just spinning in circles trying to solve this.
