First, thank you to Hanumant Deshmukh for being willing to answer questions about the book.

Given that the OCP 21 examination has not yet been released - will there be an electronic update when the examination comes out, in case of gaps between the book and the actual exam? (I realize that we can probably guess what will be covered and/or can do our own revision on the gaps, but one likes to be prepared.)

Thanks!

Yes, I do plan on doing that.
To get the updated version, you will need to follow this procedure mentioned on Amazon book page:


We enhance the content of this eBook and publish it on Amazon frequently. The build number is updated upon each release. If the build number mentioned on the title page of your copy is older than the one mentioned here, please contact Amazon support to get the latest build on your device. You will then need to delete the book from your Kindle device and download it again.

Hello,

Please can you tell me is OCP Java 17 & 21 intended for total beginners or it requests  knowledge prerequisite of previous Java versions?
I  have  OCP Java 6 Professional Certificate and would like to know what would be best next step in my certification path.

Thanks in advance.

Kind regards,
Vedran

Only basic programming knowledge and exposure to Java is expected. If you can write a hello world program in Java, that's enough.

If you already have OCP Java 6 certification, I believe you have more than a decade of Java programming experience. If that is the case, it is hard to say what would be the best certification for you without knowing your objective. Unless your job requires you to have a particular certification, your experience will count more than the certification. You can always learn new Java features without appearing for the certification exam.

Agree. There may be no point in sitting a new exam.

I can only talk about my experience here, but I found that, unless I pro-actively start using the new feature right away (not always possible at my current job), I will forget about it almost instantly.

One advantage to take the exam is that it forces you to study the new feature really well, instead of brushing through it quickly. Which may or may not help you remember it better in the long run.

Up to one's own judgement if that, on its own, makes the exam worth it or not ^^

Thank you for reply and your opinion.

Don't you think that  re-certification after 10 years is good way to update knowledge or get informed about new changes/upgrades in Java technology?
Despite fact that working with Java everyday for multiple years, it is hard to say that someone master or have good understanding on every segment of Java, especially in latest versions?

Yes, keeping oneself updated in the IT business is required to survive. But you don't need a certification to keep yourself updated. You can just read books and if you are not sure whether you have mastered the topics covered in the certification exam, you can take mock exams and see if you are able to pass them. That's will cost you a lot less

There are, of course, exceptions such as CISCO or other product based certifications, which one might need to refresh from time to time. I don't think Java is in that category though.

The story is different for beginners. Just like a degree, Java certification can add a lot of weight on their resume.
