well i don't have a tutorial, but i made some test with that and ill print you my classes.

 

I ADMIT I COPY PASTED. i dont reaaally know what exactly is doing what and why.

 

on a side note. i do know a lot about procedural generation and simplex/perlin noise, you *might* want to look at those before considering generating terrain as they are the source of minecraft terrain generation

I'm not going to go into the details, but "noise" in this case is a set of randomly generated value that can output result that looks like terrain you shouldnt have to touch this unless you're doing something very very very very very very very very very specific, like very very very!!
