Hi,
I've done a lot of Java-related projects in the past, and having done so gained me a thorough understanding of the core language as well as a number of it's libraries (network, filesys, swing UI, ZIP, etc). In a position I held before, I was also responsible for training junior developers, therefore I would be a good choice for tutoring a beginner like you.
If you would like to know more, feel free to get back in touch.
My rate for this is 17$/hr.
Cheers!
