Trailer ↠´ Java 8 Lambdas PDF by ↠´ Richard Warburton Short and concise book on java 8This books cover all aspect of java8 in concise manner One of the good book I read on java 8. a good book to introduce lamadbas i have read these chapters 2,3,4,5,6,8 and feel useful and understandable. but if you really want to know how to use lamabdas,you should use java8 in your real project,and check the java8 api for real practice at that time,the book will give you value. the chapters 9 is a little difficult to understand,the chapter 8 can teach you some design pattern through lambdas,but is a little repeatable. If You Re A Developer With Core Java SE Skills, This Hands On Book Takes You Through The Language Changes In Java Triggered By The Addition Of Lambda Expressions You Ll Learn Through Code Examples, Exercises, And Fluid Explanations How These Anonymous Functions Will Help You Write Simple, Clean, Library Level Code That Solves Business ProblemsLambda Expressions Are A Fairly Simple Change To Java, And The First Part Of The Book Shows You How To Use Them Properly Later Chapters Show You How Lambda Functions Help You Improve Performance With Parallelism, Write Simpler Concurrent Code, And Model Your Domain Accurately, Including Building Better DSLsUse Exercises In Each Chapter To Help You Master Lambda Expressions In Java QuicklyExplore Streams, Advanced Collections, And Other Java Library ImprovementsLeverage Multicore CPUs And Improve Performance With Data ParallelismUse Techniques To Lambdify Your Existing Codebase Or Library CodeLearn Practical Solutions For Lambda Expression Unit Testing And DebuggingImplement SOLID Principles Of Object Oriented Programming With LambdasWrite Concurrent Applications That Efficiently Perform Message Passing And Non Blocking I O Too much material in too little space. The first chapters guide the reader in the discovery of lambda expressions and streams They are easy to follow but are by no means comprehensive and they lack rigor Some parts are only sketched and discussed briefly omitting important details. Later chapters will reference material never explained in those chapters, leaving the reader puzzled as to where that was covered. The book goes on to discuss accessory but important topics including testing, debugging, design patterns and refactoring existing code to include lambda expressions The author also gives suggestions on when to and not to use lambdas and when parallelizing code with streams can affect performance The discussion of these topic A quick introduction to lambdas in Java 8 However, if one like myself is familiar with functional programming e. g. , F , SML , then this will be a short read as lambdas aren t that different from higher order functions and there aren t too many nuances in Java. First, this book is not for everyone from my perspective It is oriented on people who many years in Java and what to switch from Java7 to Java8 Second, this book has a good examples and describe many concepts, patterns, common design decisions but I felt as I need in depth look and examples to see and try concept from different angles. To summarize, this book is for people with 3 years of Java experience my subjective opinion who want to switch from Java7 and need short guide about what is new in Java8. If one s familiar with lambdas in Java 8 the first part of the book would be not very useful What I really liked are the chapters about Completable Futures and Parallelism.
Covers the material well This book would have gotten 4 stars, but I think there are a few places where it s just plain misleading In particular, the details about parallel and performance could lead to assumptions about easy payoffs from simply making stream operations parallel Warburton does acknowledge the safety needs here i. e. , making your data immutable and such but he doesn t really address the fact that the simple parallelism offered here can quickly lead to decreases in performance and unpredictable behavior This is a serious enough concern that I thought it worth knocking a star off my rating That said, if you want to quickly get up to speed on the new Java 8 functionality, this is a solid resource for doing so. Does lambdas really well.
