Java 8. Przewodnik doświadczonego programisty
Cay S. Horstmann autor "Java. Podstawy. Wydanie IX" i "Java. Techniki zaawansowane. Wydanie IX" - najpopularniejszych w Polsce podręczników do nauki Javy
Java to język, który zrewolucjonizował świat programistów. Jej możliwości zostały docenione przez największe firmy. Dziś Java jest wykorzystywana w najbardziej zaawansowanych projektach. Wszędzie tam, gdzie są wymagane najwyższa wydajność i bezpieczeństwo, nie ma sobie równych! Aktualna wersja tego języka wprowadza wiele nowych konstrukcji i usprawnień — jeżeli chcesz błyskawicznie je poznać, zacznij od tej książki.
Została ona napisana specjalnie z myślą o osobach chcących rozpocząć kodowanie z wykorzystaniem nowości z Javy 8. Jest przeznaczona dla doświadczonych programistów, lecz zawiera też podstawowe informacje na temat technik programowania obiektowego, wyjątków, typów i składni. Dzięki temu możesz błyskawicznie wdrożyć się w nowy język programowania! Natomiast jeśli znasz już Javę, z pewnością zainteresują Cię informacje o wyrażeniach lambda, projekcie Nashorn oraz nowym API do operacji na datach i czasie (JSR 310). Książka ta jest najlepszą lekturą dla wszystkich programistów zainteresowanych językiem Java oraz nowościami w Javie 8!
Jeśli posiadasz doświadzenie w programowaniu Javy, praktyczne podejście Horstmanna i przykładowe kody pomogą Ci szybko wykorzystać wyrażenia lambda, strumienie i inne usprawnienia wprowadzone zarówno do języka jak i platformy Java. Horstmann omawia wszystko, co powinni wiedzieć deweloperzy na temat nowoczesnej Javy, przedstawiając:
konkretne i efektywne omówienie wyrażeń lambda, umożliwiające opisywanie działań za pomocą zwięzłej składni;
dokładne wprowadzenie do nowego API strumieni, które bardzo uelastycznia i zwiększa wydajność pracy z danymi;
kurs programowania współbieżnego, który zachęca do projektowania programów na poziomie współpracujących zadań, a nie niskopoziomowych wątków i blokad,
aktualne omówienie nowych bibliotek np. do obsługi daty i czasu,
inne nowe mechanizmy, które są szczególnie wartościowe dla programistów aplikacji serwerowych lub programistów urządzeń mobilnych.

Leaves you wanting the whole book. Almost like a sample.

Good, quick information!

Very good introduction to Java 8. Sometimes technical books are too verbose (or just want to brag with 100's of pages of tech info, usually putting some generated documentation into the book). This is different; okay it is called "...for the really impatient". The book goes through all the major updates and provides exercises (which I did not do for lack of time). I also like the view "back" to Java 7, which already introduced some helpful features.
The "beef", however seems to be in Java 8, and I hope for a quick and widespread adoption. While I generally agree with bringing Java into shape I am also pensive about what kind of language this now is. It is no longer you grandma's Java, which was relatively easy to learn. This is a full-featured monster and requires good know how. That's where I need to improve. I hope I get the chance.

Не советую читать данную книгу начинающим. Всё очень сухо. Очень мало примеров в книги, что бы можно было ручками набрать и протестировать. Упражнения очень тяжелые, и совсем не понятно как их решать. Возможно данная книга будет интересна уже более опытным разработчикам, но не как не новичкам.

was a preview/early book for java 8. Since java 8 is not only out, but soon to be superseded by java 9,
this book is only of historical interest.

Focus on changes Java 8 brought including Stream API, Lambda, Concurrency changes, etc.

Excellent book, Cay Horstmann knows his stuff and he knows his target audience, which is Java programming professionals who need to keep up with the latest goings ons in Java. As Java 8 is a major update to Java, this book comes highly recommended. It isn't easy going, but as others have said it gets to the point quickly and efficiently, giving just enough background of what came before and what the new features are aimed at. There is a useful section on Java 7 too, again showing he knows his audience as I for one don't buy a Java book every time there is a Java release. I hope Cay reads these reviews, it is nice to think authors get satisfaction from positive reviews. The only reason it isn't a 5* from me is because I reserve those for special occasions!

notes/review "JavaSE 8 for the Really Impatient"
Cay S. Horstmann
4/30/14
My initial reaction to this book was that it was a "Cliff Notes" book of SE 8. It is much more than just an effort to highlight changes and additions to SE 8.
The discussion of lambda expressions - functions - interfaces, streams, parallel operations, collections, parameter types, etc., is as well covered as in any other contemporary publication. However, this author doesn't throw out diagrams to explain "how" concepts work, and doesn't present long comprehensive examples of code.
What is really unique here, is that both JavaFX-FXML, and Nashorn are given coverage with good explanations and even example code. It seems that nearly all other authors have chosen to totally ignore these aspects of Java SE. Even if the other authors consider them irrelevant or too new to be well developed, the topics are there and are being ignored. This book even gives useful examples for scripting, and points to the replacement of Swing.
There are chapters here devoted to the revised Date and Time API, concurrency changes, a section summarizing Java 7 "new" features that are important in Java 8, and a section for miscellaneous changes to the topic items of strings, the numbers class, new math functions, collections classes changes, annotations, nulls, and a few other items.
This book is not designed to initially teach any aspect of the Java language or platform.
I have gone through it 3 or so times, and find new relevance each time and I have a fairly good background in Java having used it for development since '99. The book does seem to require research or parallel documentation at hand in order to fully grasp or expand some concepts.

“Java SE 8 for the Really Impatient” is a fairly thin book (200 pages) that covers what's new in Java 8. And some of the features that were new in Java 7.
The book doesn't skimp on detail. The first 60 pages teach you about lambdas, stream and functional programming. I like how Cay covers so many different scenarios. The book is fast moving and doesn't have a lot of fluff. This meant I had to read some sections a few times to grasp the material.
The book also covers smaller changes in Java 8 such as the new way to create a Locale. I particularly liked the examples for the Instant class to deal with dates. And it was cool learning what UTC (doesn't exactly) stand for.
Even in the Java 7 section, I learned things. For example, I didn't know about Objects.equals() and the new supertype for reflection based Exceptions.
Each chapter ends with hands on exercises. I haven't tried them yet, but doing so is on my to do list.

I really enjoyed reading this book and my favorite part was the exercises at the end of each chapter. Going through the exercises and actually trying to write programs with the new java 8 api was a very educational and challenging experience.
My least favorite part of the book was the lite coverage of lambdas. There was only 1 chapter on lambda expressions. Even after reading the book, I don't feel really proficient and comfortable with lambdas, so I think I'll need to find another book to strengthen my skills in that area. (Note - the 1 chapter on lambdas was good - I'm just not familiar with them from another language and would have liked more examples/tutorials on them).

A pretty good intro on java 8

Like his previous book on scala, this one is a pretty good intro on java 8. it will definitely be on my desk for quick references.

Very good overview and good explanation of the new interfaces for FP in Java. Also catch up of other new cool stuff in both Java 7 & 8.

Very dense and thought provoking. Love the way he took the time to write up programming exercises to test your comprehension.

A clear and concise introduction to the features of Java 8. This assumes that you have full knowledge of the Java language up to at least Java 6.

It's for the really impatient :-)

It is a good summary and concise introduction to Java SE 8. Not for laymen, as it focuses con the changes/deltas un this version of the language.

A good book that gives you an overview of the new Java 8.
June 12, 2015
The best introduction to Java 8 features I've seen so far. Very practical, with exercises and open questions to think of.

Great book and reference
Really enjoyed the book and it's quite thorough and the examples are useful and easily applicable in your daily work.
