Hi Stefan Salatic, welcome to Programmers! This is way too broad a question: whole books have been written on the subject. That said, I've closed your question as a duplicate of another closed question so that you might gain some insight as to where to begin to narrow down your request. – user8 Nov 28 '11 at 21:21
Thank you for introducing me with the question posting policy. I will try to make my questions more precise and narrower next time. – Stefan Salatic Nov 28 '11 at 21:35

The often-overlooked Java tutorial is a good start:

http://docs.oracle.com/javase/tutorial/reallybigindex.html

I'd say everything up to (but not including) the deployment section is 100% essential, then jump to Collections, then Reflection and Generics.

You should also know about jars, packaging applications and libraries, using an IDE, knowing some Ant/Maven.

I'd say that's the "required" Java SE "core" knowledge.
