How to use the atom text editor with git -java-

Question

I am trying to use atom with git to work on a coding project with some class mates, for this particular project we are supposed to practice making different classes. I just pulled the most recent version of the project from git and I now see that they were successfully able to create new classes/tab-things but have it still within the main file. How do I do something like this in atom? I can't ask them because they use a different ide.

In the picture you can see different classes in drop-downs but its still within "project2" - how do I do this for another class and have it in a new drop down and upload it to git?

From the screen shot, those dropdowns appear to simply be diffs from the git log. So if you want your changes to appear in a similar fashion, you'll need to create the classes (or additional files) and commit/push them.
