This book is teeming with mistakes. Singleton implementations are broken(the current idiom for singleton is enum singleton, static class holder(described in this book) is an idiom for safe publication only, but it does not work for singleton because there can be several classloaders in JVM) - double checked locking in this book misses volatile keyword, which is crucial. Nevertheless, the book confirms that implementation does not work and says that "the problem was reportedly fixed in Java 5". Guys, I've bought this book for Java 7 certification, of course it should reflect changes made in Java 5.The authors also do not distinguish the difference between widening of primitive types and upcasting of classes.The sum() method on page 166 creates n Double object wrappers, instead of using primitive double variable etc. and so on.This book also contains many groundless optimization tips, for example it states that final classes in Java are more efficient, because "the method calls are resolved in compiler time" . That is wrong for Hotspot JVM, because it's smart enough to apply analogous optimization looking whether the method is effectively overriden in subclass or not - it's done during the classloading and has nothing to do with final keyword.You should not justify twisting your code only by a hypothesis that there may exist some JVM where some specific optimization *may* work.P.S. sorry for my English I'm not a native speaker.
I bought the Kindle version. It's only like $20 or so. I'm studying for both the OCA and the OCP at the same time. I have my OCA scheduled in a few days, and I'll schedule my OCP later. I've noticed that this helps me with my OCP preparation as well as my OCA. I recommend it, as well as reading the online Oracle Java learning trails, and the enthuware.com mock exams. These three resources will help with OCP. I have an excellent book for the OCA, which of course paired with enthuware.com mock exams and the learning trails.Update- I completed this book the first time. It's like 650 pages. I will re-read it and then take the enthuware mock exams I bought (which they updated for me recently). I like the book, I like the writing style, I believe in the content, and it's nice to have somebody gather this information for me in a way that helps me target the exam. I'll update this when I get results on my exam. My recommendation is to read it twice, and I'm following my own recommendation. 650 pages is a lot of information to take in.Update- After reading this book twice, taking and reviewing both included exams, reading the online Oracle.com Javadocs for the OCP JP SE 7 certification, getting a wee bit of practical experience, and taking and reviewing all 5+1 associated Enthuware exams, I passed the 804 exam on my first try. I got a 70%, where 65% is a passing score. This book was an important introductory step toward getting this certification. The study process up to today (June 9 2014 pass) took me 6 months of part-time study.I recommend studying this book as a part of the above steps to prepare for the 804 exam.
I used this book to study for the OCPJP Java 1.7 exam. It prepared me. I used Mock Exam 1 as an open book test. Good thing I did it as open-book because several answers were wrong. In particular this : Question 83 asks you to choose 1 correct answer from 4 possible code snippets. The problem is that two of them are right. The answer book says "Options b) and c) uses the finally block, which is not applicable with try-with-resource." Which is incorrect. The FINALLY clause is perfectly acceptable with try-with-resource. Some of the questions also had typographical, syntax, and grammar errors, which make it seem as if they rushed to press without bug-proofing the exams.Otherwise, this was a good study aid. It seems comprehensive.
Neat small explanations of the topics covered by the exam(I hope!). I will find out in about a month when I think I should be ready. I took the OCJCP7 1Z-805 exam last week and scored 81. The mock exams in this book are much more difficult than the real exam - so they are a great preparation. Also the exam I took is the "upgrade" exam, so it covered additions to Java 7 not in earlier versions, like the Java NIO classes and new Concurrency util classes - a lot of the questions in book are on more general Java concepts like threads, inner classes, static references and overridding, etc., which are not the focus of the upgrade exam.
Even with the errata provided by the writers, the book still have errors. The writers appears to be not supporting this book anymore, because I wrote a question to writers, asking about a new error, and I don't have a answer. If you want to pass on the OCPJP 7, I cannot suggest only this book. I would suggest the OCA/OCP JavaSE7 (Kathy Sierra and Bert Bates) plus this one, plus Oracle Official Docs. There are some question you will find in this book and don't will find in the OCA/OCP book.This Exam is heavy, and you must have a mock exam to get the practice of the snaky questions. So, I think that using all these sources mentioned, you can pass on the exam, with 5 months of studying. If you already are a Java Programmer, and program a lot, I still recommend that you study a lot!
When I started reading this book I liked the authors approach and also the way important concepts were highlighted. However as the reading went on I din't feel that the topics have been covered in depth and also lacked coherence. In short not justified.For someone who wants to understand Java in depth, and at the same time prepare for certification, there is no alternative to Head First. Having said that since its not yet available for Java 7, I will suggest using the complete reference also if you are going with this book. Or using Head First and preparing the V7 changes from another source.This book is fine but lacks depth and falls short in explaining things in details.
