Track: Java - Not Dead Yet


Day of week:

Java is continuing to evolve to meet modern developer and business needs, from the introduction to lambdas in Java 8 to built-in support for money types rumoured to be in Java 9. In this track we'll hear from experts on the cutting edge, and those who are building successful businesses using Java.

Track Host:

Java 9 is just around the corner, and yet many of us developers have yet to use Java 8 features in an application. The goal of this presentation is to move beyond slide-sized examples of streams and lambdas, and to show how to build a fully working end-to-end application using just the core libraries available in the latest version of Java.

In this session, Trisha will build a Java 8 application live. This application will consume a real-time feed of high velocity data, contain...

This talk will cover the experience of adopting Scala in the digital enterprise. It will provide technical and development advice to agile teams new to implementing Scala. Learning a new programming language is tough, even if you think that it has similarity to your current day-to-day language and shares the many of the same advantages of it.

Just like Java, Scala is statically typed and compiles to byte codes, it runs on the Java Virtual Machine. Yet Scala has different style, syntax...

How many times have been told how functional programming is so much better than imperative, and then being presented with a functional approach to calculating a fibonacci sequence, leaving you wondering how that can be even remotely useful when working in real world applications? Yep, we've all been there. It seems that every time someone wants to explain functional programming to us, it’s around how to solve some mathematical problem. But how does that provide us value? How do we deal with...

Six years ago DRW Trading was primarily a Java shop, and I was primarily developing in Ruby. Needless to say, it wasn’t a match made in heaven. Fast forward six years, Clojure is the second most used language in the firm, and the primary language for several teams (including mine). Clojure wasn’t the first language that I’ve introduced to an organization; however, it’s unquestionably the most successful adoption I’ve ever been a part of. The use of Clojure has had many impacts on the firm:...

Java is fast. Really fast. But the memory layout of object arrays is an area where Java still inherently lags (in speed) behind the C family of languages.


This session introduces org.ObjectLayout a new Java package designed specifically to enable JVMs to optimize memory layout for arrays and objects in a way that closely matches the performance behaviors of arrays of structs and struct-in-struct in C. ObjectLayout is designed to work on any JDK (version 6.0 and above),...

Open Space

Join Trisha Gee, our speakers, and other attendees for the Java Open Space.

What is Open Space?

Every day at QCon London, we’ll open space five times, once for each track. Open Space is a kind of unconference, a simple way to run productive meetings for 5 to 2000 or more people, and a powerful way to lead any kind of organization in everyday practice and extraordinary change.
