Lambdas: Myths and Mistakes - Presented by Richard Warburton (1 hour presentation)

tl;dr - How will the everyday developer cope with Java 8’s Language changes?

Java 8 will ship with a powerful new abstraction - Lambda Expressions (aka Closures) and a completely retooled set of Collections libraries. In addition interfaces have changed through the addition of default and static methods.

The ongoing debate as to whether Java should include such language changes has resulted in many vocal opinions being espoused. Sadly few of these opinions have been backed up by practical experimentation and experience.

* Are these opinions just myths?
* What mistakes does a developer make?
* Can a ‘blue collar’ Java Developer cope with functional programming?
* Can we avoid these mistakes in future?

In London we’ve been running a series of hackdays trying out Lambda Expressions as part of the Adopt-a-JSR program and have been recording and analysing the results. This gives us unprecedented insight into what will happen in future.

Who should attend:

All types of developers - its a pretty high level talk.

    Really insightful talk about the pitfalls and decision making behind Lambdas in java 8 - developers new to this space should see this as mandatory viewing!
