Java Tip of the Week #4 – Lambdas

posted by Roberto Cortez on

Java Tip of the Week #4 - LambdasThis week Java Tip of the Week is the sequel to last week Streams API episode.

Lambdas is definitely one of the most awaited features in Java. Quoting Mark Reinhold – Chief Architect of Java Platform Group, Oracle:

“Lambda is the single largest upgrade to the programming model. Ever. It’s larger even than Generics. It’s the first time since the beginning of Java that we’ve done a carefully coordinated co-evolution of the virtual machine, the language and the libraries, all together. Yet the result still feels like Java.”

Lambdas is what make the new Streams API really powerful. Nothing was stopping Java to come up with a behaviour based API to perform operations on a sequence of elements. But who wants to code like this:

First Coimbra JUG meeting – The new Java 8 Features

posted by Roberto Cortez on

Last Thursday, 19 December 2013, the first ever meeting of Coimbra JUG was held on the Department of Informatics Engineering of the University of Coimbra, in Portugal. I couldn’t be more proud, more than 50 people attended the event.

After a quick intro to the JUG by myself, explaining the JUG objective and purposes, we had Samuel Santos from PT.JUG to share some of his experience running and managing the biggest JUG in Portugal.

The highlight of the meeting was the my talk about the new features in Java 8, especially lambdas. I think that most of the people enjoyed it, but maybe it was not that interesting for the folks that already use lambdas or equivalents on other languages. Also a lesson learned for me.

If you’re curious, here are the materials (in portuguese):

You can find more photos of the event on our Meetup page. We also have a few videos that I’m uploading right now. I’ll update the post when I’m done.

A special thanks to Jetbrains for giving away 2 free licenses of IntelliJ 13 to raffle among the participants. Congratulations to the lucky winners of Math.random(), Hugo Lopes and Luis Rosa.
