These are the slides of my talk at Devoxx 2013.
This presentation introduces the lambda expressions, how we can write them, and what they bring to us developers. The second part presents in details the new patterns introduced by the Stream and Collector APIs. These new APIs will change the way we process large collections content, enabling concurrent and parallel access, with a very simple programming model, and amazing patterns. Complex examples will show how powerful those APIs are, and how they can help us write efficient and clean code.
