Resources to learn JAVA

Hello /prog/ next semester I'm going to have an OOP class and we're going to use JAVA the "problem" is we'll have to learn JAVA by ourselves since the teacher will only explain OOP stuff and won actually teach us the language. The question is what are good resources to learn the language?

P.S. I don't know if it matters but i have some experience with C.

"hackers" and "crackers" is a concept that is just as stupid.
There are idiots in any culture or sub-culture and that includes programmers as well. Whether or not a concept is relevant to its original meaning is defined solely by the "masses", whether they be several million individuals or only a couple.
 Language is only a vector of thought, and the masses determine the common usage of language, making a term obsolete or not.
In this case, OOP's term is de facto diluted and now englobe C++, Java, Python etc..

Whether you like it or not won't change the fact that it now has a new meaning.
