So making this conversion who is gonna call this method might not notice it until the exception happens.

I would not necessarily "draw any straight lines."  What to do/when always boils down to meeting business needs/requirements.  Certification study aids/guides/books/websites aren't always guides of how to do things in the real world, rather their ultimate aim is to help us achieve certification objectives.

For example in OCAJP Associate Java 8 Programmer Certification Fundamentals: 1Z0-808 by Hanumant Deshmukh, there are plenty of "side notes" to that effect.  Example:

Just like the cast operator, the instanceof operator is also used only sparingly in professionally written code. Usage of instanceof reflects a bad design and if you feel the need to use instanceof operator in your code too often, you should think about redesigning your application.

By the way, TH is using instanceof very appropriately.

I hope that helps,

Hi Iuliana,

Does Amazon's January 21, 2020 release date in combination with this "early" promotion indicate that you may possibly be releasing earlier than expected?  If not, will the winners of this giveaway potentially be receiving an "early release" edition of your book?

SNAPSHOT ... which I had no idea of in my past experience is NOW very high on my list. (Unfortunately, Eclipse may be the closes thing to IntelliJ IDEA my employer may swing.)

Thanks for the well thought out answers!

From my only other thread so far  

iuliana cosmina wrote: Everything you need to learn Spring is already publicly available. Most books just add in a suite of learning steps, a learning track and a project that lets you see how Spring can be integrated with other technologies; like different databases, Docker, Gradle, etc.

I was hoping you could talk me, among others, into purchasing your book specifically, rather than allowing us with past experience, especially, to more easily think with those already publicly available (potentially disparate/outdated) resources may be "just enough" to allow us to jump back in.

As I interpret from Amazon's description with your other thread against the backdrop of my past experience potentially, your book provides one (concise) resource that more easily consolidates the information in a format that is specific to passing the Pivotal Certified Professional Core Spring 5 Developer Exam, while bridging past Spring gaps potentially, and still being very much useful for practical professional everyday current on-the-job use today.  Correct?

Hi Iuliana,

In addition to purchasing your guide, what other resources, and more importantly why, do you personally recommend for someone like myself that will be getting back into Spring on upcoming projects from my old Spring MVC [2.x] days?  

Hi Iuliana,

Congratulations on the second edition of your exam guide!  

I have been away from Spring for quite some time.   Now, I find that I need to get back into the swing of Spring due to changes in the technology choices at different places of work.  I only very recently noticed that certification was an option.  I also noted that there are guide(s) available from Pivotal's Certification site.  Could you please pitch me on why it would be to the benefit of people like myself, with former knowledge of the [2.x] Spring Framework, to purchase your guide instead of relying on the aforementioned official guide(s) and/or other more freely available resources?

Lots of demand for Java developers. I did a lot of Java development during grad school, but I've definitely fallen out of practice. Certification seems like an attractive option for me. I know the Java 11 certifications are out, but from what I have read they are significantly more difficult than the Java 8 OCA exam. Would it be worth getting a OCA certification in Java 8, or is that considered a waste of time, and just go for Java 11?

Personally, if I were in your shoes, only after hitting a "brick wall" on any possible commuting, teleworking, completely moving, and/or other possibilities were completely exhausted in attempts to leverage your existing skills, I would likely aim for Java 11 since the Java release schedule shifted, from a major release every 3+ years to a feature release every six-months.  

Oddly, the official OCP 11 FAQ, complete with information regarding notes, mock exams, and much more, doesn't (yet) have Enthuware's latest very successful (if I may say) book launch recently.

Very well wishes on your next steps forward!      

Akshay Good luck in your preparation.

Akshay Kamat wrote:Hello,

This is my first post in the forum. I have recently started studying the OCA Java SE 8 Programmer I Study Guide by Jeanne and Scott. I have a fair amount of knowledge in Java and want to schedule the OCA exam. However, I'm confused with when should I schedule it with respect to me completing studying the entire book.

As BG alluded, after consistently scoring above 80% or more on mock exams, many will then schedule as a safer bet to successfully earn each cert.  If you aren't aware, scheduling is actually the second step.  You would first need to purchase an exam voucher.  One of your book authors, Jeanne Boyarsky, previously mentioned this discount.

I want to echo CR, Welcome to the Ranch!

I bought the mock exams for Java 8 and I'm scoring about 80ish.

Because you've already run the race,  I'd say go ahead and cross the finish line.  It sounds like you are already meeting the threshold.  If you are confident, then run, don't walk, to take the OCA 8 exam while the material is still fresh in your mind.  Afterwards keeping in mind what CR says and/or if you like to keep your certs "fresh", you can then pursue 11 Part 2, or "just" stick with 8 OCPJP.  Although afterwards, personally I would go with the former since it's "closer" to Java 13.
Hi Preety,

The only correct answer is ... (drumroll please)  ...  it depends.

What's more important to you?  For future proofing, Java SE 11 Programmer I 1Z0-815 is your only answer.  Are you already in or will be going to a Java 8 environment, Java SE 8 Programmer I 1Z0-808 is your answer.

You could potentially just split the difference.

Good luck on making a decision that is right for you.

Given that my current company is still rolling out Java 8, I assume that studying the books that I already purchased and obtaining both the OCA and OCP Java SE 8 certifications is the best path forward for me.

We are in the same boat.  Because I had already invested time in preparing for 1Z0-808.  I intend to go forward with it.

Jason Lawson wrote: But, I am curious to know if there would be any advantages for me to forgo the OCA / OCP Java SE 8 certification path and jump directly to the new Java SE 11 certification path.

Afterwards, I was thinking of upgrading.  Good luck on making a decision that is right for you.
