I suggest you start by learning php or python first, they're the easiest programming language to learn, then after you know a bit how programming works you can try java. (Which is a fairly difficult language to start with, trust me, I know.)

I also recommend books, specifically the head first series, I'm using it for C# and it's a great book, with a lot of illustrations, examples and little assignments.

and if you want to work with programming problems (Like math problems, y'know, those things nearly everyone hates)
