The only problem with this, is when people come here trying to make a mod with little to no java experience, to the point of not understanding classes, methods, properties, inheritance, overrides, etc, it all goes back to "learn java".
I do agree that the amount of "java training" needed will vary from person to person, but unless they do not plan on coming here to ask questions and instead seeking the answers themselves, they should probably learn a decent amount of java first before attempting to mod.
