Shows readers how to use Stream and Spliterator

Author has more than 30 years experience coding

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.

What you'll learn:
• What are lambdas and streams and how to use them
• What is the default method
• What are streams, the stream() function
• How to use Stream and Spliterator
• How to use parallel streams
• How to do collectors and concurrency
