JDK 8: Lessons Learnt With Lambdas and Streams

Simon RitterThe JVM guy!

Lambda expressions and the streams API add a more functional style of programming to Java; something developers have not really had in the past.

This session will start with a short summary of the key features of both Lambda expressions and streams before moving on to some real world examples of how to use them effectively, including a number of lessons learnt from trying to apply an imperative style of programming when it should have been functional. We'll finish off with a quick look at some of the ideas for improvements to streams in JDK 9.
