Java Talks

We alternate between "Stammtisch" and "Java Talks" every other month. "Java Talks" will be held at a venue with presentation equipment in place. The first "Java Talks" meetup will be held on September 30th, location TBA.

Speakers are welcome! Get in touch with the organizers if you would like to contribute. Talks should be in the range of 20 - 30 minutes (If you plan a longer talk, that's also possible - but that would mean we reduce the number of talks) - bring your own Notebook if possible.

Talk 1: Matthias Endler: CQRS

CQRS (Command Query Responsibility Segregation) is an architectural style developed by Greg Young. CQRS has its roots in CQS (Command Query Separation) which was invented by Bertrand Meyer. CQS is the idea that a method in a class should always only read or write the state of an object. CQRS lifts this principle into the architecture of the data models and splits it into a read and a write model. The talk will give an overview on CQRS with the help of a practical example and will shed light on the pros and cons in relation to the classical two or three layer architecture.

Talk 2: Gernot Kvas: A quick glance at functional programming features in Java 8.

Java 8 truly becomes a multi-paradigm language with the addition of Lambda expressions and the Stream API in the Collections framework. This talk gives an overview over the new features we face in Java 8.
