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.

The Java and C++ guys disagree, which is exactly the problem: OOP is a handwavy, bullshit marketing term with no rigorous definition. Java and Sepples' OO is no more or less legitimate than Javashit's chained hash-tables, Ruby and Smalltalk's procedure-calls-by-another-name and reflection, and whatever other obscure ontology-and-agents system terminology he is invoking.
