Feedback / Pimp my Code

Hello Everyone. I am just getting started learning java and the forge api at the same time. I know I need to get better at Java before I can be a good modder. But I learn best when I have a practical project to put my code to test. I have some programming experience in other languages but modding and java is a first for me. So as a educational exercise I created a fake mod that has a road map and everything (road map is WIP)

It's currently called "Patina" and ads some weathered looking blocks to the game. But I plan to add some items, and machines as part of my learning process. I thought I would post a link to the source code and solicit your feedback and suggestions on best practices or point out what is a dumb idea, or how we can do things better. In my other programming user groups we call these "pimp my code" sessions. Basically people open up their source code so others can learn from it, or use it as a teaching aid. We find the open discussions make us all better programmers...

I don't know how big this modding community is on helping people get better, but I thought I would stick my neck out there and hope it doesn't get bitten off.

Fire Away....

Thanks for the critique diesieben07. I definitely felt my code could use some refactoring.  I assume that by using metadata I could could pass it all the necessary args like hardness, footstep, unlocalized name etc. Is that correct? Is that what you meant?

Thanks for the tip on the language file. I will look at that in more detail. Sounds like a good idea.

Thanks for the clarification. Let me reply with a scenario. What if two blocks have different hardness levels  or harvest levels. Example. Iron blocks can be mined with a stone pickaxe, but a diamond block requires an iron pickaxe or better. Can this be achieved with metadata? My initial thought is no but I am probably wrong
