Modern Java in Action: Lambdas, streams, functional and reactive programming

The only regret that I have about this book is taking 6 months to get deep into it after I bought it. I recently had a coding challenge, which I completed successfully, but using some archaic for-loops. I knew a little about the Java Streams API but not enough to use it intensely. Had I finished this book, my performance in that coding challenge would have been much better. The book guides you sequentially from Lambdas, to method references, functional interfaces to streams in a way that builds up to skills and tools that will blow your mind. Even before the authors used the word SQL to describe what Streams manipulation does with collections, I had reached that conclusion. For instance, the filter() is like a Where in SQL. The sorted() is like an Order By in SQL, etc. Basically you'll learn how to query your collection by chaining. And that's just 1 3rd of the book. My Java fundamentals have been enriched or "modernized" beyond measure. It's fun to actually code the examples and break them and play around with them. My next coding challenge will be off the charts for sure.

The beauty of this book is that the authors gradually build the lessons from the things that you already know. Comparative learning is the best kind of learning and the authors have done a brilliant job with their teaching approach. Almost all other java 8 books and tutorials start with abstract stuff like “functional interfaces” with the “runnable interface” as the example, assuming people are experts in these topics. Most java authors really prefer to drown their readers in esoteric obscurity, like the language itself. But the authors of Modern Java in Action explain everything step by step, taking you by the hand until you grasp the concepts completely. That’s the hallmark of a great book. Really looking forward to their next book if they plan to write one.

Love it. All of it's content helped me understand hard things to get. A must to read for Java developers

The material is well covered and clearly explained. My only issue with the book is that the author tends to babble a lot. At least 15% of the sentences in the book could simply be removed without reducing content or readability.

In general the book has a very good organization. Well written. Many practical exercises. Many questions to go on your own to consolidate what you've learned. Highly recommended. My search for a well written Java (Introductory) book has finished with this.

Bought the first edition of this book, currently reviewing this edition. A thorough knowledge is displayed in both editions. It is an exciting time to be involved in Java programming.

Really good book

The book content is good. But the quality of the paper is so bad. When I use a highligher, I can see the highlight color on the reverse side. Note that this is a $55 book, not the $5 mass copy.

Very useful ! It was a pleasure to learn from this book everything is clear And we’ll explained plus additional sources ! I recommend this book for old fashioned Java developers wants to invest in a functional style Java programming

Currently working as Junior Java Dev, the book gets to the point. I jump back and forth a lot in this book. Comes handy when I need to review certain things

Un libro che ti prende per mano e ti porta in un viaggio alla scoperta delle funzionalità delle moderne release di Java (>= 8)

Great content and clear examples

The authors have collected the key features of Java in one single book. Therefore, no need to spend more time on searching online resources. (They are very useful as well )
