New language

Alright so i'm not a professional coder but i tought i'd start learning Java.
So now my question to /prog/ is: does anybody know any good places i can start learning Java? Like good PDF's or sites?
And what is the best compiler according to you?

There is no clear distinction between compiler, interpreter, JITer, etc. -- you're all stupid for arguing about it. Though I agree with #2. Java is a horrible language.

Scala has all the positives of Java with far less of the crap. Unfortunately there's less documentation for beginners.

To be honest just learn Haskell and take over the world.
