I passed my exam one week ago. It took 3 weeks of preparation for the exam. I used the OCP guide by Boyarsky & Selikoff and Enthuware.
I did prepare before for Java 6 years ago, which is obviously a stretch from Java 8.
Java 8 was dominated by Streams and Functional Interfaces. But I am an Oracle developer, so SQL in right in my alley. And I don't know if anybody noticed, but the similarity is clear. I believe Lukas Eder has an article about this.
The point is to me, streams and functional interfaces were the easiest part of the exam including collectors. Generics on the other hand, not as much.
I wanted to share my experience and take advice for what to tackle next.
I aim for the OCM. However, Oracle is retiring the Jee 6 OCE, so the path is not clear. What should I do?
