Java Quick Syntax Reference (The Expert's Voice) 1st Edition, Kindle Edition

If you need to quickly review Java syntax, this is it. Straight to the point, it will allow you to acquire the key concepts fast.

I love it

This is OK and is identified as a Quick reference so expectations shouldn't be too high. However I also have a Java 7 pocket Guide by O'Reilly that seems much more comprehensive and is in an even smaller format.
