I myself am a hobby programmer and already worked with many different programming languages (Ruby, Batch, Python, lua, JavaScript, PHP...). Java was a new language but it's not that hard to learn if you already know programming in general. Mevans gave me access to the source code first to help me finding information (eg. the biome IDs or the invasion/bandit chances for each biome). I helped the community a lot with my  knowledge (example) and I understand Mevans plans for this mod. That's why Mevans considered to let me help him with the coding.

If you want to learn modding, I suggest you to look at the source of other mods to look how they did it. Unfortunally, Mevans just removed the LOTR mod source from GitHub, so you can't get this code anymore.
