I found a great Java programming site awhile back. I was given a programming task and could get immediate feedback on whether or not it was correct. Tasks were things like, test if two integers are equal and 'reverse a string'. It was targeted toward learning .. but I seem to recall the tasks had advancing levels of complexity. This is not Java BlackBelt. I can't believe I didn't bookmark it. Anyone know what I'm talking about?

I'm looking for a library, package, product or some sample code in either JAVA or Visual Basic that would allow me to create a video from my program. I have some software tools I've developed and I'd like some functionality to my program that could take existing video clips and pictures and then assemble them into a video. I would like the final video format to be FLV however any popular format would do. Any help would be greatly appreciated. Have a great one.

I am very comfortable with Java and reasonably comfortable with C++ and Visual Basic. I do not have any work experience in programming and won't have the chance to gain any before graduation(the unconventional schedule of my current job is what is allowing me to finish my degree in the first place).

Can anyone suggest a book, website, etc. that describes the process of breaking a problem down in order to write a program. I have struggled for far too long trying to figure out how to write a program from scratch only to be stumped by the logic involved.

This question, I think, is outside of a specific language or philosophy (Java, OOP, et al.). It's just something I haven't been able to get my head around.
