With the release of version 8, functional programming has finally come to Java—bringing a brand new way of thinking about code. It is an update like no other in Java’s history, introducing new syntax, new libraries, and a new programming paradigm. This guide will help you make sense of these changes and keep you on top of the latest Java programming techniques. Written concisely by a veteran Java practitioner, it is perfect for developers wanting working knowledge of Java-style functional programming.

  • The complete anatomy of the lambda: An analysis of lambdas, method references, default methods, and functional interfaces.
  • New and improved libraries: A description of the standard functional interfaces and the newly functionalized Collections library.
  • Streams: A look into the Streams library, how to think in streams, and how to best use streams—the most exciting Java 8 feature.
  • Parallelism: A discussion on functional-style parallelism for modern multi-core CPU architectures.
  • Java functional theory: An overview of Java-style currying, higher-order functions, partial application, and functional composition.
