The file attached is a project I did for college/university (I'm going to my third year of Computer Science/Electronics). If you have any questions about it feel free to ask. To give an example of how it should work, go to the tests function and execute any of the files, RecipeTest.java uses most of the code during its execution.
I'm mainly interested in helping the Iron Armada team comment and refactor their code. There was a heavy emphasis on this while we were learning Java in college (client-based object-oriented programming) and making sustainable code is important. I'd also really like to learn more about Java and Git in a 'real' setting. (I understand the push/merge/pull parts of Git, and even used it for my project, but I haven't used Git Labs or anything related to that).
