About this book

Lambdas and Streams are language elements that have been found their way into the Java world with version 8. This book wants to introduce in their concepts in a concise form.

For this purpose it is necessary to introduce a couple of new supporting features like functional interfaces, default methods and more. Once introduced, streams can be parallelized in a very simple way - within certain limits, no knowledge about the thread management is needed. This will be handled transparently behind the scenes. Nevertheless, some basic things in the context of parallelism need to be considered. Here, the book provides a variety of information from practice.

The aim of the book is therefore, to provide all relevant information around the topic Java Lambdas and (parallel) Streams. With this book, you should be able to use this technology in your own projects. You are invited to report how well this has been possible and to send feedback to the author!
