A small collection of examples and the slides for my talk "Better Java Code With Type Annotations" (german: Besseren Java-Code mit Type Annotations).
If you want to build the slide use the following commands (on MacOS or Linux):
cd slides && npm install && npm run bower && npm run watch
The slides are also available on https://www.thecodecampus.de/slides/2016/etka-jsr308/ or at slide share
