Сертификация OCAJP: материалы для подготовки

Сертификация Oracle Java Programmer (OCAJP) позволит вам получить официальное звание Oracle Java Programmer, которое, безусловно, украсит ваше резюме. В этой статье мы составили перечень материалов, которые помогут при подготовке к сдаче этого ответственного экзамена.

Стоит отметить, что если вы всё же решились на этот шаг, не стоит недооценивать коварность составителей тестов. А значит, будьте готовы потратить личное время на подготовку.

Соответственно, речь идёт об экзаменах первого и второго уровня. Первая часть относительно проста и требует базового понимания JavaCore и ООП, однако встречаются как вопросы на внимательность, так и хитрые формулировки. Вторая часть заметно сложнее — для успеха вам потребуется более глубокое знание Java. Есть много вопросов по Stream API (до 40 %), в том числе и вопросы по знанию всех intermediate- и terminal-методов. Также надо будет знать все функциональные интерфейсы с точными сигнатурами их методов, причём наизусть. Могут встретиться и вопросы про смену летнего времени на зимнее в LocalDateTime. Некоторые экзаменуемые пишут, что только около 30 % вопросов связаны с пониманием, а порядка 70 % — это, по сути, вопросы на заучивание методов API из Javadoc.

Интересный момент: в связи с пандемией сдавать экзамен сегодня можно в режиме онлайн.

Для эффективной подготовки рекомендуют много материалов, лучшие из которых мы собрали в один список. Некоторые из материалов уже не новы, но до сих пор полезны. Необязательно изучать все из них — лучше выбрать наиболее подходящий и работать с ним каждый день.

Книги:

1. «OCA Java SE 8 Programmer I Certification Guide», автор — Мала Гупта (Mala Gupta). Охватываются вопросы, необходимые для сдачи экзамена OCA Java SE 8 Programmer I Certification (код 1Z0-808). В книгу включён и полномасштабный пробный экзамен.
2. «OCA: Oracle Certified Associate Java SE 8 Programmer I Study Guide: Exam 1Z0-808» — Жанна Боярски (Jeanne Boyarsky), Скотт Зеликофф (Scott Selikoff). Прекрасная книга для подготовки к экзамену OCAJP8, представляющая собой наиболее полное изложение вопросов OCAJP8. Начинается с теста для проверки своих знаний и включает в себя много примеров для изучения как новых, так и старых принципов Java.
3. «OCP: Oracle Certified Professional Java SE 8 Programmer II Study Guide: Exam 1Z0-809» — те же авторы, но речь идёт уже о втором экзаменационном уровне.
4. «OCA Java SE 8 Programmer I Study Guide (Exam 1Z0-808)». Содержит сведения от первоисточника, то есть Oracle. 3-е издание написано Эдвардом Финеганом (Edward Finegan) и Робертом Лигуори (Robert Liguori). Можно неплохо попрактиковаться, т. к. есть много упражнений и компакт-диск с двумя полномасштабными пробными экзаменами.
5. «Oracle Java SE8 Programmer Exam Self-Practice Review Questions for Exam 1z0-808». Книга для отработки вопросов экзамена OCAJP8. Включает в себя более 120 вопросов для тренировки. Может использоваться для повышения качества подготовки вместе с любой из вышеназванных книг.

Также для подготовки рекомендуют:

1. Тренажеры enthuware: 1Z0-808 JA+V8, 1Z0-809 JQ+V8.
2. Форум CodeRanch.
3. И, разумеется, туториалы от Oracle.

Есть и ещё один путь подготовки — пройти соответствующий курс в OTUS, который на момент написания материала не имел аналогов в России.

Hi there! So this is a complete resource guide for my attempt to get Java 11 Certified. On the 18th, January 2021, I passed my «Oracle Certified Professional: Java SE 11 Developer» certification.

So I started my journey to get certified in Java 11 to receive Oracle Certified Professional Java SE 11 Developer credentials. Before 1st, October 2020, it was fairly a two-step process:

• Take a 815 exam Post 1st, October 2020, it is displaying a 404.
• And a 816 exam Post 1st, October 2020, it is displaying a 404.

Both costs approximately 11,300 INR each and covers a different set of the syllabus.

You have to purchase the exam voucher from Oracle for each one of these. The voucher will be valid for the next 6 months. And during this period, you can schedule the exam anytime.

I did that too, but as soon as I was prepared for 815, THE Oracle changed the game. They were retiring both 815 and 816 in favor of 819.

And as if 2020 was less weird, Oracle discontinued Java certification test 815 and 816. And in place of it, Java Test 819 was introduced. The new 819 exam

Few features of this new exam

• It is a 90 min exam as compared to 180 min ( for 815 and 816 each ).
• The total number of questions is reduced to 50, and you need to mark 34 questions correctly to pass.
• It costs approximately 18,538 INR plus taxes.
• Covers almost all the topics from exam 815 and 816, with few exceptions. Check out the 819 links for a detailed syllabus.
• You will receive «Oracle Certified Professional: Java SE 11 Developer» as Oracle recognition.

Below are the list of some of important topics and resources that is used to prepare them.

Stream, Lambdas and Funtional Interfaces

• Streams, Lambdas, Functional Interfaces
• Stream API Java 8
• Stream Operations
• Stream Tutorial
• Processing Data with Java SE 8 Streams
• Method detail of Object class This is important because many times we are asked to identify a Function Interface and an inteface with no abstract method and a Object class method is not a function interface.

Secure Coding in Java SE Application

Helpful resources from Oracle

Github Resources from my fellow wanderers

• Selikof/Boyarsky book ( Oracle Certified Professional: Java SE 11 Developer : Complete Study Guide)
• Enthuware 819 Mock Test

Java Code in this Respository

• Basic : Inheritance, Arrays, Final, Initialization, Overloading, Overriding, Primitives, etc.
• Advanced : Annotations, Collections, Concurrency, Enums, Exceptions, Functional Interfaces, Generics, Inner Classes, NIO2, etc
• Streams
