Todd G. and Mykola D.


Need help with a project? Would you like a second pair of eyes to dig into that tricky issue you’ve been facing? Or do you just want to hang out with your laptop and some people after work? We’ve got just the thing for you! Introducing CJUG Office Hours! We always have an optional group project going on in case there aren't a lot of questions from the group.

Optional Group Project: Design Patterns! Nick will go over some common design patterns you're likely to run into, what problems they solve, and how to implement them in Java.

Office Hours are hosted after work. Every session will have at least one aide in attendance for the full session. The purpose of these sessions is similar to that of a ‘coffee and code’ - connecting with people who want to work on personal projects, get a code review, or just hang out. There is no set format and you may come and go as you please.
