Beginner Java Game Developement

Hi,
I have been teaching myself how to code in java for a few months. I know the basic things like arrays, loops and all of the beginner stuff. What I really want to do is to learn how to make games. My brother takes a course at his school and I see him making all these really cool games like pong and such. I would really like to do this. Where would I start game developement? What concepts in java would I have to know? And are there any really helpful websites with tutorials on what I would need to know? I am currently 14, so I am not a genius, I am only looking to do the very very beginner stuff and then work my way up to harder stuff. Any help would be really appreciated.

Thanks
:)

Look at how to do GUI and how to draw on a component like a JPanel.
The Java tutorial has lots of example programs.
The Java™ Tutorials
The Really Big Index

I already know a fiar bit of GUI, like JFrame and JButtons with actionListeners and JLabels, Shuold I focus on the graphics parts now? WHat do I do after that?

Retire. There is enough there to keep you busy for a long time.

Enough where?

GUI & graphics

I know but how shuold I start, and what are the prequisites I shuold know before I start trying to make games, and also learning how to paint graphics won't teach me how to make games. I mean its the first step but whats next?

Learn how to use the graphics features first.
Next could be networking
