    I'm a big fan of Functional Programming and a working Java developer at JDK 6 for app server compatibility That's where I'm coming fromThis is an EXCELLENT book for developers who are thoroughly familiar with good ol' Java and want to know about the promise of fp style programming in the Java ecosystem The book is exactly as long as it needs to be Explanations are brief but edifying code samples are useful The discussion is a nice mix of Hows and Whys Whies? along with some tempting Whats The attitude of the prose is helpful conspiratorial and confidentIf you're looking for a single serving introduction to Java 8 Lambdas I don't think you'll find one better than this Another excellent resource is Brian Goetz's State of the Lambda found here

    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 ie making your data immutable and such but he doesn't really address the fact that the simple parallelism offered here can uickly 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 uickly get up to speed on the new Java 8 functionality this is a solid resource for doing so

    Does lambdas really well

    Too much material in too little spaceThe 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 detailsLater chapters will reference material never explained in those chapters leaving the reader puzzled as to where that was coveredThe 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 topics is very brief however and refers to oversimplified situations that rarely if ever apply to real world scenariosThe book is well structured and balanced but fails to provide a sound introduction to the basic concepts and only sketches the surface of advanced topics

    a good book to introduce lamadbas i have read these chapters 234568 and feel useful and understandablebut if you really want to know how to use lamabdasyou should use java8 in your real projectand check the java8 api for real practice at that timethe book will give you valuethe chapters 9 is a little difficult to understandthe chapter 8 can teach you some design pattern through lambdasbut is a little repeatable

    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 anglesTo 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

  7. Venkatesh-Prasad Venkatesh-Prasad says:

    A uick introduction to lambdas in Java 8 However if one like myself is familiar with functional programming eg 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

  8. Snejy Snejy says:

    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

    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
