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?

If you use some retarded definition of compiler that only allow for translation to the exact instruction set for a physical machine, then yes, Java isn't compiled, but then again neither would be C on any architecture that uses microcode.

As such a definition would be useless, it is allowed to compile to the language of an abstract machine, like that of the JVM, which includes other high level programming languages.

As for your ``challenge'', just fucking Google it.
