Java Lambdas and Parallel Streams

by Michael Müller

This compact book introduces the concepts of Java lambdas and parallel streams in a concise form. It begins by introducing new supporting features such as functional interfaces, default methods and more. After this, the author demonstrates how streams can be parallelized in a very simple way―within certain limits, no knowledge about the thread management is needed. Nevertheless, some basic elements in the context of parallelism need to be considered. Here, the book provides a variety of information and best practices.

A good brief introduction to Lambda stream. Still, it doesn't go through everything about it. It explains a bit the mechanism of the Functional interfaces, Lambda expressions, Stream, Spliterator, ParallelStream and the main Stream operations such as filter, collect, reduce and map/flatMap. It uses one example through all the chapters, which adds elegance to the book. Only 90 pages, concise and clear. But it ends with many remaining questions in my head. To go in depth, one should read some other book.

Wanted more detail. I know he was trying to create a short and comprehensive introduction but some places needed more explanation, like the Java concurrency and collectors part.

Very clear and rich of examples of code

Ok, not easy to talk about this IT book. Well firstly that's a small book, it's only 65 pages (without annexes). You can read it easily in a few hours. So according to me, it's too short to explain lambda and streams. It's a kind of quick introduction to that topic, if you are looking for a detailed story about lambda and streams, don't buy it. Personally I don't get the interest of such books.
