Java 8 Lambdas: Functional Programming for the Masses

If you’re a developer with core Java SEskills, this hands-on book takes you through the language changes in Java 8triggered by the addition of lambda expressions. You’ll learn through codeexamples, exercises, and fluid explanations how these anonymous functions willhelp you write simple, clean, library-level code that solves business problems.

Lambda expressions are a fairly simple change to Java, and the first part ofthe book shows you how to use them properly. Later chapters show you how lambdafunctions help you improve performance with parallelism, write simplerconcurrent code, and model your domain more accurately, including buildingbetter DSLs.

• Use exercises in each chapter to help you master lambda expressions in Java 8 quickly
• Explore streams, advanced collections, and other Java 8 library improvements
• Leverage multicore CPUs and improve performance with data parallelism
• Use techniques to “lambdify” your existing codebase or library code
• Learn practical solutions for lambda expression unit testing and debugging
• Implement SOLID principles of object-oriented programming with lambdas
• Write concurrent applications that efficiently perform message passing and non-blocking I/O
