Lambda Expression Authority Guide

"Proficient in lambda expression: Java multi-core programming" describes how the lambda-related features in Java SE 8 help Java meet the challenges of the next generation of parallel hardware architectures. This book explains how to write a lambda, how to use a lambda in flow and collection processing, and provides a complete code example. You will learn how to make the most of the performance improvements that today's multi-core hardware can bring by using lambda expressions.

Main content:

Why do I need a lambda, how does it change Java programming

Lambda expression syntax

Basic operation of flow and pipeline

Using collectors and pooling to terminate pipelines

Create a Stream

Split iterators, fork/join frames and exceptions

Using a micro-benchmark test to check the performance of a stream

Using the default method to evolve an API author introduction .

Maurice Naftalin has more than more than 30 years of experience in it and has served as a developer, designer, architect, manager, teacher, and author role. Naftalin is a certified Java programmer who has used various release versions of Java. His experience in Java and business gave him a unique insight into the fundamental changes in the introduction of lambda expressions in Java SE 8. Naftalin is a frequent fixture at various conferences, including the annual JavaOne. He works with the Oracle development team to run a popular web site,--www.lambdafaq.org, which focuses on the new language features in Java 8.Table of ContentsDirectory
