While not relevant to the primary focus of this club (Apple/Xcode), I still believe this information might be relevant to some people.

Funnily enough, I actually find that a good book can be more useful that online tutorials (more so for beginners). This is why I would recommend the book "Sam's Teach Yourself Java in 24 Hours". This is the first Java book I used and I think it is pretty useful for a beginner. I probably wouldn't buy it, since once youve read it and
done all the examples it is basically dead weight, however, I would definitely borrow it from a library if you are interested. (Not sure if its at scotch.)
This book will get you from a complete beginner to a proficient programmer in Java. However, this hasn't even started talking about game programming, which is an entirely extra layer of skills to add to your "toolkit". That's where the next book comes in...

Yesterday, Apple announced a number of things (iOS 8, Mac OS X 10.10 to name a few). One of those things was a new programming language for developing Apple apps. It is called Swift and is a bit like "Objective-C plus Python plus JavaScript plus C++". Although it is designed to complement Objective-C (not replace it), now Objective-C will no longer be considered "cool" (if it ever was).
Just a bit of news...

It is a new language. It is meant to be Objective-C without the baggage of C. It is based on the same LLVM compiler and is fully interoperable with Objective-C. According to apple's (probably unrealistic) performance benchmarks it can be up to twice as fast as Objective C. To me it looks like Objective-C crossed with scripting languages like JavaScript and Python, incorporating "modern" language features like namespaces, closures, tupls, dynamic typing etc.
