I think that you'll do better leaving tutorials alone and switching to Java books. Eckel's "Thinking in Java" may be a good start for it is freely available
online, so you may begin your Java adventure right from the spot. Also, you may want to check Horstmann's & Cornell's "Core Java". If you've had any contact with object-oriented programming languages in the past then, you'll find Java an extremely easy language. If you've descented from procedural BASIC, like me, then it will take some time to learn it.
Good luck!
