Free Java Project Downloads

Hi Guys.

Im doing a project in java with mulipile screens and im wondering if anyone knows where i can download sample project code that i can get ideas of layout from.

There is 1000s of tutorials for creating one page layouts in java but none to show muliple different screens.

Let me know if anyone wants to share some of there projects that they have worked on our know any sites where i can download them.

Thanks in advance

Kevin
