The Definitive Guide to Java Platform Best Practices-Updated for Java 7, 8, and 9   Java has changed dramatically since the previous edition of Effective Java was published shortly after the release of Java 6. This Jolt award-winning classic has now been thoroughly updated to take full advantage of the latest language and library features. The support in modern Java for multiple paradigms increases the need for specific best-practices advice, and this book delivers.   As in previous editions, each chapter of Effective Java, Third Edition, consists of several "items," each presented in the form of a short, stand-alone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why.   The third edition covers language and library features added in Java 7, 8, and 9, including the functional programming constructs that were added to its object-oriented roots. Many new items have been added, including a chapter devoted to lambdas and streams.   New coverage includes Functional interfaces, lambda expressions, method references, and streams Default and static methods in interfaces Type inference, including the diamond operator for generic types The @SafeVarargs annotation The try-with-resources statement New library features such as the Optional interface, java.time, and the convenience factory methods for collections… (més)

Nem véletlenül ez az egyik legismertebb Java könyv. Nem teljesen kezdőknek ajánlott, vagyis feltételezi, hogy már ismerjük a nyelvet, de pár év Java programozás után már rendkívül hasznos lehet. Sőt szerintem vannak részei amik akár már korábban is teljesen érthetőek.

A könyv 12 fejezeten belül 90 pontot sorol fel. A fejezeteken belül a pontok egymásra épülnek, de a fejezeteket szinte tetszőleges sorrendben olvashatjuk. A pontokban a szerző tipikus Java programozási hibákat mutat be (és persze azt is, hogy miként lehet ezeket elkerülni), vagy felvet egy gyakori problémát és szépen kidolgozott programozási technikát mutat be amivel megoldhatjuk. A könyv egyik legjobb tulajdonsága, hogy a pontok szinte mindegyike konkrét javaslatokat tartalmaz. Vagyis nagyon ritka az olyan megfoghatatlan szabály, ami általánosan javasolja, hogy törekedjünk valamire.

Érdemes odafigyelni, hogy melyik kiadást vesszük meg. Én a harmadik kiadást olvastam, ez 2017-ben jelent meg, több újdonságot tartalmaz a 2008-ban megjelent második kiadáshoz képest. ( )

This book alone made me a better Java programmer. Period.


Pros:
* It's presented by items, so no need to read it sequentially;
* Contains a glimpse on the intricacies of the Java language;
* Contains code examples on 'why do this, but not that';
And more importantly,
* You'll probably consider things that never even crossed your mind (or at least, not mine).

Cons
* It's geared towards Java 2 and... Java 7 has just came out. In my eyes, it doesn't make it less valuable though.


Even though I just finished the first edition, I'm seriously considering buying the last one. I liked THAT much. ( )

This book not only provides gems of advice for core Java programming but also for programming in general, especially if your code will be provided as an API to other programmers and if it is going to live for more than a few months.

Another interesting aspect of the book is that the more I contemplate upon it, the more it resembles like advocacy for functional programming. At least some parts really made me think like "hmm, that would be considered natural in Scala" (insert your favorite functional programming language here, even if it's not purely functional in the strictest academic sense). The book is also helpful if you've spent long time in high level languages such as Python or Lisp before coming to Java, and are curious about how you can get an approximation of some of their good parts such as optional named arguments.

The foreword of Guy L. Steele, Jr. says it all: after learning the vocabulary and grammar of a language you need to master the pragmatics of it rooted in real life cases so that your communication with other language speakers will smooth flowly. Bloch's book helps you with that effectively and I think every programming language deserves at least one author of Bloch's calibre. ( )
