OCP Java SE 17 Developer - Edge cases

[Jorge Ruiz-Aquino]

Hi Khalid/Vasily,

I know the list of changes from Java 11 to Java are the ones below:
[1]: Text Blocks
[2]: Pattern Matching for the instanceof Operator
[3]: Java Records
[4]: Sealed Classes and Interfaces
[5]: Switch Expressions

I've seen the new syntax for those topics and are completely different of what pre-Java 17 developer know.
Do you present edge cases in your book? Those that are rare in the professional life but could be asked in the exam? Like which ones?

Hi Jorge,

I believe edge cases are exceptions rather than the norm on the exam.  

Our book is comprised of two volumes, standing at about 1800 pages.
The reason for its hefty size is that topics are covered thoroughly, without glossing over details.
That should give you some idea that edge cases are covered where it is felt necessary.
It is a tall order asking which ones are covered in the book.
I let that be a surprise for the reader.

Wow, that is almost an encyclopedia! Then, it could be taken as a Java text book for a new Java programer?

Don't let the size of the book put you off.
You can go through the book non-linearly, concentrating on the topics that need reenforcing.

[Khalid A. Mughal]

The book can be used as a Java text book and also as a Java reference.
It will also function as a doorstopper, if the need arises. :-)

I think it's worth mentioning that the book contains extensive questions at chapter ends. Running through those will help you understand whether you need to learn more about that topic, and quite possibly refresh your mind on some details you might have been on the verge of forgetting.

Generally, exam question writers are not supposed to focus on testing edge cases. However, sometimes certain concepts are best highlighted when contrasted with the edge case. Thus an exam preparation guide generally follows same approach and looks into edge-cases when they help to shed some light on a given language feature, or a behaviour.

FWIW I did review for some of the chapters and they are very thorough. Any time I thought a topic was not covered and I found it on the next page
The tests Simon mentioned at the end of the chapter were tricky and solidified the concepts.
