L2J Server

OK! So first of all I KNOW I'M A NOOB, you don't have to remind me.. now that thats out of the way.

I want to begin working with JAVA, I want to learn, but, I have NO Idea where to start, or rather how.. I mean, I know only the very BASICS of running an L2J server (compiling, patching, etc) nothing more. I want to learn to code for myself (and eventually others), I need a push start . All of you had to start some where.. where did you?

Where can I begin 'this journey of Java', can you recommend me any software?websites? something, I have no clue where to start my 'studies'.

There's also one somewhat good playlist of tutorials on Youtube:

By `somewhat` I mean that the guy often makes typos (though he usually fixes them) and usually explains things 2-3 times (though some of the public actually require that).
Also, of course, as my signature says - practice makes perfect. To learn something it's not enough to just read some books or watch some videos, you need to do it to get it.

P.S. If some more people throw in good links, this should be made a sticky.
