Hi Jeanne, Scott,

I've achieved the OCP Java 8 (thanks to your previous version   ), but I'm thinking to get the 11 also (None of them required in my current job). Do you think is there any advantage of having both?
Some friends got the Java 5 or Java 6 certifications and got the Java 8 too. It's there any advantage for them to pursuit the each new one?

Thanks.

It depends what your motivations for obtaining the certification are.  If you’re looking to obtain a sound education and increase your knowledge of the Java language, then certs are a good way to meet this goal.  If you’re looking to improve your resume or land a job, certifications may help but they are often just one part of a larger package.

What’s the most important reason you took the cert in the first place?

In my case was to increase my knowledge. I thought preparing for the certification was the best option for me to learn Java 8.
I used your previous book and indeed I learnt and approved the exam.
Sadly we are still using Java 6 at the job. That's my motivation to get certified, also, I hit two targets in one shot.

Well, improving your knowledge of Java is always a good goal!  As for using Java 6 at work.. my condolences.  I'm pretty sure Java 6 contains a number of unpatched security vulnerabilities at this point, though, so move to something newer as soon as you can!

He'll have to learn NIO and try with resources and streams and λs and quite a lot else even without getting as far as Java9.
