Java Docs for CC

I have been programming in Python for the past few years in code combat, and I recently saw that there was Java, so I decided to try it out. I have been running into some bumps and would like to know if there are Java Docs for Code Combat. I am also ok with Beta Docs in GitHub, I am familiar with reading code. If there aren’t any docs, are there test cases or actual code that I can see to help me out?
