Mastering Lambdas: Java Programming in a Multicore World (Oracle Press)

Learn to effectively use Lambda expressions to take full advantage of performance improvements provided by today's multicore hardware Mastering Lambdas: Java Programming in a Multicore World provides you with a complete grounding in the theory of Lambda expressions, and the rationale for their introduction and use in practice. This Oracle Press guide reviews a simple Java code fragment iterated over a collection, poses different challenges, then delves into the fundamentals of syntax and basic use. The book recommends best practices for adding Lambda expressions to an existing library and explores the changing Collections Framework. You will walk away with a comprehensive understanding of how to implement Lambdas and a solid rationale for the why. Provides complete grounding in the theory and practice of Lambda expressions Author runs a popular tutorial site in collaboration with Oracle's development team, lambdafaq.org, focused on the new language features in Java Covers the fundamental mind shift, theory and syntax basics behind new Lambda expressions - more than just the how-to

The Definitive Guide to Lambda Expressions

Mastering Lambdas: Java Programming in a Multicore World describes how the lambda-related features of Java SE 8 will enable Java to meet the challenges of next-generation parallel hardware architectures. The bookexplains how to write lambdas, and how to use them in streams and in collection processing, providing code examples throughout. You'll learn how to use lambda expressions to take full advantage of performanceimprovements provided by today's multicore hardware. This Oracle Press book covers:

• Why lambdas were needed, and how they will change Javaprogramming
• Syntax of lambda expressions
• The basic operation of streams and pipelines
• Using collectors and reduction to end pipelines
• Creating streams
• Spliterators, the fork/join framework, and exceptions
• Examining stream performance with microbenchmarking
• API evolution using default methods
