hi folks

I would like to learn more about 3-tier architecture(presentation, business logic, data) programming in java. Does anybody know a good tutorial (or a book)? Especially tutorials about building a sample application would be very interesting.

Any proofen tutorial would be a help

Thanks

Hey there

I've solved the problem, did the following:

Interface:


and then I've created an abstract class aList:


and Class ListOne:


and Class ListTwo



Is that a good solution?

Thanks

Hey there

I'm working on a exercise and got the following problem:

I wrot this Interface:


and I've implemented this interface in Class ListOne:



At this point, everything seems fine and okay

Next Step:
I have to implement the a Class ListTow with an LinkedList instead of an ArrayList and of course I should reuse as much as possible code. I know that I have to refactor it :-), but what is now the approach? Should I create an abstract Class for ListOne and ListTwo or how should i proceed?

Thanks a lot for any hints

Cheers
Stefan
