OCAJP 7 vs. 8

Hello!

I have some questions regarding the OCAJP 7 and 8 exams: I have several years of exerience with Java development (Java 6 and 7). Additionally I had the chance to take part in a preparational course for the OCAJP 7 exam. My score in realistic mock exams was above 80%.

Now I am unsure whether I should now take the OCAJP 7 exam or if I should invest some more time and prepare for the new OCAJP 8.

Does anybody of you know, how big the difference between the two exams actually is? As far as I can see here, there are only five topics that are new/extended in the new certification. Are these the only differences? What would be the best way to prepare?

Thanks,
Leon

IMO getting OCAJP 7 makes no sense when OCAJP 8 is available and out of beta.

I didn't take any of those exams yet, but I am preparing for OCAJP 8. As I was reading about the exam I learned that every new exam adds content about new features from actual Java version, and kicks out deprecated and no longer recommended stuff. For example, OCAJP8 adds questions about the new date and time API and removes the ones related to the old way of handling date and time. I read that questions about fundamental things like arrays didn't change in years.

So, if you have good knowledge in Java 7, educate yourself about new stuff in Java 8 like lambdas and so on to prepare for OCAJP8.

Hi Leon Mueller,

First of all, a warm welcome to CodeRanch!

In the recent past, there were some reasons to opt for the OCAJP7 exam instead of the OCAJP8 exam. For example: limited choice of study guides, the OCPJP8 exam still being in beta, no OCPJP8 study guides available,... But at this moment, these reasons are no longer relevant anymore. So unless you have a very specific reason to opt for OCAJP7 (e.g. a requirement of your employer), you should prepare and take the OCAJP8 exam. It is currently the latest and greatest!

You have already found the mapping between the exam objectives for OCAJP7 and OCAJP8. And for the OCAJP exam it is indeed a very limited list (for the OCPJP exam the difference between both versions is much bigger). If you are an experienced Java developer, you'll probably need maybe 1 (or 2) weeks to study the new/extended exam topics.
You can use online tutorials, articles, resources to study about the new and extended exam topics. Or you can buy an OCAJP8 study guide, go through this book and focus on the new/extended topics. With the latter you are almost guaranteed to have a complete coverage of all exam topics. And to test your knowledge and have an objective indication of your current level, some mock exam software might be useful as well.

In the OcajpFaq (besides other very useful information) and this thread you'll find an overview of all available resources (study guides, mock exams,...) to thorougly prepare yourself for the certification exam. And on the OcajpWallOfFame you'll find plenty of (links to) experiences from other ranchers (including resources they have used). So it can be useful to determine which resources are useful (and which are not).

Hope it helps!
Kind regards,
Roel

Thank you very much for your help! I think I'll try the OCAJP 8 exam.
