Java 8 Lambdas: Functional Programming For The Masses

I'm not a Java programmer, but I'm looking around at how various languages are implementing functional programming lately. Anonymous methods were introduced in Java 7, but they were fairly clunky and verbose. The language developers seem to have done a great job at really honing in on what it takes to make them useful and have tailored the language and the entire Java ecosystem to support their use. This is important: simply souping up the language wouldn't be sufficient.I've found the information in this book to be highly informative and encouraging.

This books cover all aspect of java8 in concise manner. One of the good book I read on java 8.

Since last few months, I have been trying to find a good book on learning lambda expressions thoroughly. I tried with some of the books available in market but this books is the one which I like most. It covers each and every aspect of lambda expressions with proper exercises which helps people learn more. I truly recommend this book if you're interested in learning Java 8 lambda expressions clearly.

The book gives good examples, and even does comparative examples between imperative and functional programming so the reader really gets the full experience when learning ! ! ! !

Just what I was looking for -- sharply focused and written for the non-amateur.Rather expensive, but worth the cost.Will no doubt be referenced by future treatments of the same subject.

The first half of the book gives a concise and clear explanation of the basics of Java 8 Functional programming. However, the author appears to have rushed through the 2nd half, especially in design patterns and concurrency, with sections of in-cohesive explanations of patchy code sections of otherwise interesting examples. It would have been OK if complete samples code is included in the code-download site, but some of the more interesting samples are completely missing from the downloaded zip files. For example, the Domain Specific Language from chapter 8 and the Non-block IO Chat program from chapter 9 are no where to be found.

I'd already been dipping my toes in the water with lambdas and wanted to broaden my knowledge of the new Java 8 features. This book gets to the point quickly and provides good takeaway advice for when and how to leverage them. On top of that, the author does a good job relating the features to each other so the topics build upon each other and earlier concepts get reinforced.

If you want to speed yourself up in java lambdas and you are a Java programmer - This book is a must read
