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.

But since "OOP" as a term is diluted it doesn't really matter, its a dead term long finished off by 500 mediocre C++ books, long before Java had its first release. Its not like "pure FP", which everyone knows exactly what that is, even if the details of the side effects are left up to the language designer.
