Java Practice Questions: Oracle Certified Associate, Java SE 7 Programmer (OCAJ) 1st Edition

Good practice for taking the exam, even though I did not see many of these types of questions on the real exam. These questions are in general more difficult and tricky than the ones on the exam. It helped practicing with questions in the same format as the real test.

A few chapters in and I have found quite a few errors. Some where no answer match the described solution, some where the questions are formulated so that the answer describes a non-matching case. This makes me unsure if I have other questions right even when I check the answers..Otherwise the questions are tricky and answers describe solutions well. Each one helps you understand obscure rules in Java a little better.

The questions provide an insight to how the test questions are phrased. The examples came in handy during test time

It has very good practice questions but I think they are not enough, it needs the double I think to be a complete in my personal opinion. Anyway, whoever reads this book, will learn a lot about the topics in the exam.

The questions are well researched and the explanations are well done. This is a great addition to other books when preparing for the OCAJP exam.

I keep finding mistakes in answers and content that are not on the OCA test. Wrapper classes are not on the test and he has several questions on them. Mala Gupta's book is much better. Also, lots of typos.

Excellent exercises for practicing. I highly recommend it.

Questions are at times even more absurd then the exam questions

It's hard to complain about a technical book that costs only a few pounds. For the price, it's hard to fault this book -- it does exactly what it claims to do: offer a large number of Java 7 exam practice questions. The questions seem to cover the necessary syllabus areas and, with a couple of rather startling exceptions, those questions that have unambiguous right/wrong answers are answered correctly (with an editor and a compiler on hand, it isn't hard to check). The answers to those questions which call for interpretation or value judgements are more, well, questionable. How should one answer this question, for example "An abstract class with all abstract methods is equivalent to an interface (T/F)?" That seems to be something calling for an essay answer, rather than a true/false. Sadly, this is a problem with the multiple choice format itself and, no doubt, affects the examination as well as this book. Be that as it may, I think there's room for more detailed explanation of many topics in the answer section.The chapter dealing with inheritance and polymorphism struck me as a bit rushed. There's a couple of places where the answers don't seem to match the questions, as if the author changed his mind about the ordering and didn't check the changes thoroughly enough.It's notable that this book does deal with the new features in Java, such a string-valued switch statements and multi-catch exceptions. There aren't many exam books covering these subjects yet.I would guess that the author doesn't have English as a first language. The English is pretty good, to be fair, but it would benefit from a good English-speaking technical editor.On the whole, worth the money; but with the faults I wouldn't have wanted to pay any more.

Very well structured and organized. A very valuable book for practising and preparing for the exam.The way that the author groups the questions into topics is really good. And the overall quality of questions and explanations of answers is excellent and well written. I only noticed 2 main mistakes which were in the answer section: Page 149 and 157 (sections 1.3 and 1.11) 'synchronyzed' has wrong spelling.The questions are designed to be hard, and some are very hard. But it's a learning aid to help you with the exam.There are only 120 questions in total, which is not really enough. I found that using additional practice exams from Whizlabs helps as well, to practice the topics that were learned in the book.

There are far too many mistakes in this book. There are examples of answers given that do not exist in the options. There are also too many examples where you view the answer and the answer is not correct and does not match up with the explanation. I would only consider buying this if you already know java well and can work through these mistakes. If you are new to java then these practice questions may easily confuse you.

This book gives the question from objectives of the old exam format, which may confuse the candidate with the exam topics. Ex: topics such as enums, operator such as (ex-or, shift) are not in the current exam objective.

Dieses Buch kann als Ergänzung zur Vorbereitung für die Prüfung OCAJP dienen. Es bietet aus allen Bereichen der Prüfung 10 Fragen. Über einen Link im E-Book kann man schnell und komfortabel zwischen Fragen und Antworten hin- und herspringen.Es sind einige Fragen vorhanden, die mir der Prüfung geholfen haben. Insbesondere schärft das Buch den Blick für alle möglichen Typen von Kompilier-Fehlern. Ich habe die Prüfung letztendlich nahezu ohne Fehler bestanden.Ich kann dieses Buch allerdings nur eingeschränkt empfehlen. Die Formulierungen sind teilweise schwammig, manche Sätze sind nicht im korrekten Englisch verfasst. Die Erklärungen sind nicht immer ausreichend, teilweise wird in den Erklärungen einfach nur die Frage wiederholt.10 Fragen pro Block können natürlich nicht alle Möglichkeiten abdecken. Das liegt aber auch daran, dass ein Großteil der Aufgaben nicht kompiliert und man deswegen nicht über das eigentliche Thema abgefragt wird.Geärgert habe ich mich über eine Vielzahl von 'Welche Antworten sind falsch?'-Fragen. Durch die Verdrehung hatte ich die Antworten im Buch nahezu immer falsch. Ich denke auch nicht, dass man die Fähigkeit für die echte Prüfung benötigt.Knapp 5€ für 120 Fragen sind natürlich nicht viel Geld, deswegen kann sich das Buch als Ergänzung durchaus lohnen. Für 10€ bekommt man bei Hanumant Deshmukh aber mit 500 Fragen wesentlich mehr für sein Geld. Auch Qualitativ ist dieses Buch deutlich besser.
