Java has come a long way - from JDK 1.0 in 1996 to Java 7 in 2011. It has been almost a year "Dolphin" has been out with lots of new features. Oracle hosted a series of events last year showing the power of Java 7 as this was a significant milestone.
Our friends at Packt has come with an good cookbook "Java 7 New Features Cookbook" having 100s of new features explored. I just got hold a copy of this. Would be reviewing this and posting a blurb on this blog.
If you are curious just like me - then head over to their site - http://www.packtpub.com/java-7-new-features-cookbook/book and explore the Table of Contents. It looks interesting.
