I had the pleasure to review JavaServer Faces: Introduction by Example by Josh Juneau which has been published by Apress in December 2014.

As you may already know, Java's Stream API is one of the most significant features introduced in the latest platform version. Aside from the lambdas, which can reduce the amount of boilerplate code in our code base, the Stream API releases us from the burden to be responsible for how collections are traversed, for example. In the pre-Java8 platform versions, we could either use an implementation...

By day two, Tuesday, my involvement had reduced to presenting one session, participating in the Hackergarten and meet the experts areas, and a panel discussion.
The day began by co-presenting a session with Heather...
