Roel Spilker -- Java Boilerplate Busting with Project Lombok

If there's too much code, and it don't look good Who you gonna call? Boilerplate busters! In this presentation, one of the developers of lombok, Roel Spilker, will show the audience several of the lombok features. [...] While most IDEs offer a feature to generate the boilerplate, this is little help when reading the resulting code, and such code is much harder to maintain.

Roel Spilker is a technology evangelist at TOPdesk. He's been a professional java programmer and teacher since 1999. Roel has been a fan of compile-time checking. Together with Reinier Zwitserloot he is the inventor of Project Lombok, a compiler/IDE plugin to bring the java programming language into the next decennium.

Pál Könyves -- Making Java functional

Functional programming support has arrived to Java as well! We'll cover why you should care and how to incorporate it in your daily tasks.

Zoltan Reegn -- Killing mutants in the PITs

Killing mutants in the PITs Code coverage is a really useful metric in determining code quality. Or is it? If we know nothing about the quality of our assertions in our test cases, we can only be sure about one thing: that what is not covered during tests is definitely not tested.

But who tests the tests? How do we know the quality of our tests? Will our tests definitely fail if an error (eg. a regression) is introduced into our code?

Join me and learn how you can test your assertions by creating "mutants" with PIT and "killing" them. After that you will be more confident that your 95% code coverage really means reliable code.
