Scala for the Impatient

Scala is reaching a tipping point, as thousands of Java and other object-oriented programmers hear about its potential and seek to discover this breakthrough functional programming language for themselves. Until now, most treatments of Scala have been abstract and academic. Now, Cay Horstmann does for Scala what he did for Java in his global best-seller Core Java he offers ...more

Very good introduction to Scala for Java Developers. It contains everything you need to know about this exciting language to hit the ground running in a new project. Of course book contains some things that are not necessarily required for a beginner Scala developer, but there are only few of them.

A must read for every Scala developer wannabe with background in Java.

Excellent for learning scala basics and interacting with the scala library. I really liked the emphasis on "for" comprehensions in lieu of map/filters. Lots of comparisons with Java throughout the book which is very useful if one is familiar with the java paradigms. The author also provides several pointers on using functional versus object-oriented techniques which can be applied across languages. Would have been great if he delved more into libraries for big data like spark or even walk throug ...more

I've started finally writing some scala at work, so was happy to have the excuse to pick this book up. Scala's an interesting language, and one I'm definitely still learning. This book certainly helped, and I'm sure I'll return to it as I'm actually writing code and thinking about how to organize my work.

This book did a pretty good job of introducing the language and walking you through many aspects, including some features you may or may not need (xml processing, parsers). As I read it, I was t

Very good book, it is well organized and teaches you the basics of Scala. I found the chapters on more advanced topics a little lacking, but that's OK since this book is focused on helping introduce you to the language. The examples used in this book get straight to the point and assume the reader has a background in software development. The only downside I found was the kindle version I was reading had formatting issues with the code examples.

Great fast-paced introduction to Scala. Covers a lot of syntax, and new things which Scala does and is advantageous is. This doesn't set out to show you how to build something from scratch, it's mostly theory-based rather than applied, but it's a good reference guide, and first-point for someone not wanting to dive into other books (tomes) on Scala.

Slight gripes, as criticisms are always easier to point out:
Could start with how to structure a Scala package/program.
Not enough on Scala's advantage

Very good. Honestly, I'd wish that the last 100 pages would have been 200 pages, with more examples and exercises. Also, the chapters on XML and parsing aren't really required, in my humble opinion. At least not if you are really impatient.

However, overall, a very good introduction for Java programmers who want to learn Scala.

Covers basic needs to start coding in Scala. I needed to learn some new syntax + ways Scala handles.

Good book for reference and gotchas and will quickly take you up to speed in scala.

Overall, I liked the book and it gives fast and good introduction to Scala. Perhaps I wanted to see also as part of the book, more focus on Functional programming in Scala.

Useful if you are already coming with some FP background and is only interested in the sintax. Go for Odersky Coursera courses to learn FP with Scala.

I have read 12 chapters of this book.
While the examples are very understandable, and the book succeeds with the key point; to teach Scala features and syntax without being overly verbose, it fails to show how to program in Scala, the examples are simply too short to be satisfactionary. As an example, in Chapter 12: While it had brief coverage on what closures, and other functional programming things are, and how to do it in Scala, it completely failed to drive home the point of the power of func

If you are already familiar with object-oriented as well as functional programming concepts, this book will provide a very concise tour of the language, without re-iterating anything you already know.

I bought the book yesterday to get an overview of Scala so that I can talk about it intelligently at some interviews I have coming up. For that purpose it's successful. The book is designed for programmers who are already familiar with Java or C++. In many places where the author could have gone into a lengthy description, he instead says "this is just like this feature you already know, with these differences." That's mostly a successful approach, but there were some places where I found myself ...more

A really outstanding lightning tour through the Scala language. My only beef is that it is occasionally too lightning; maybe I am not impatient enough. Trying to cover so much ground so fast means that many concepts are only slightly touched upon and, since the book tends to build on previous parts of the book, this left me asea at times such that I would have to go back and re-read sections as well as go online to figure things out.

However, this is a relatively minor quibble considering the gro

It worked for me! This was a great way for me to learn Scala. I come from an atypical background, though: I've done plenty of functional and object-oriented programming. I was a bit weak on the Java side of things. But I picked this book up quickly, for the most part. It doesn't waste time introducing you to programming concepts, so it's good for those who have a lot of background. I did find that in the last few chapters, some of the concepts weren't as clearly motivated as early on. I kept won ...more

That was the second Cay Horstmann’s book ive read. First one was Core Java Server Faces .

What can i cay, this book is great. Scala language is very friendly for the newcomers, and on the other side it’s very complicated and needs a lot of practice. But it’s almost impossible to tell about all the features of one language in a three hundred pages book. But Cay Horstmann really did that. He doesn’t waste your time on an explanation of basic stuff. He goes straight to the core of Scala.

Technical approach with formal definitions of Scala constructs, sprinkled with good insights along the way. Making it a good book for Java converts.

The organization of the book though requires many forward-looking references, which given the material can make it hard to comprehend some concepts. Like-wise there isn't any de-emphasis on the more complicated/obscure areas of Scala, which is what I consider the biggest problem with Scala.

I'm another developer that has just given himself a crash course in Spark/Scala. This was an excellent text for the latter. However, as a scalaNoob, this was a challenging book to work through (generics and continuations come to mind). Stackoverflow, of course, helped fill in the rest of the details.

Really good introduction to Scala. It's a good book to begin with Scala if you are already well experienced with Java or some similar language. However, it is not too detailed. And that helps to keep you focused on the important stuff. Finished in a week. I kept Odersky's Programming in Scala as a companion to this one.

Despite the title this is not to be considered a fast-forward guide which does not go into details. It has just the right amount of details to start. Much more useful than oderky's guide if you are aiming to be productive with the language in no much time.
John Fourkiotis
The book is very good as an introduction to Scala. However the later chapters that describe the advanced Scala features are too short. You won't learn when to use what features from this book, as their description is a little bit shallow.

This was the perfect scala into book for me. I prefer to get started building things and then understand the theory. So I bought this along with Odersky's book, and it has served me well. I find myself continuously referencing the examples here.

A lot of people recommend this book as a good start point for learning the Scala, so I've followed their words and read it. After all I agree that book is a good enough (but not ideal though) and it definitely will not be mistaken to start your Scala journey with this book.

Not really finished in the traditional sense. I use this book as a sort of reference when playing around with the scala language.
