Hacking Streams and Collectors

Jose PaumardThe Streams guy

Java 8 has been released a bit more than 3 years ago, with a major addition: the Stream API. This API brings new patterns to process data and new ways to organize applications. This API is not new anymore, but there are still many ways to use it that are yet to be discovered. This session is almost 100% live coding and will browse through the most important patterns of both API. Simple ones, complex one, useful ones, funny ones, well-known ones, unexpected ones. Live coding allows for interaction, questions and answers. I hope we will have fun together in this session!
