Java SE 11 Oracle Certification Review
April 29, 2021
I finally took the Java SE 11 Oracle Certified Profession (OCP) certification! I consider it to be a good certification for a developer that wants to prove a solid theoretical knowledge of various aspects of the Java language.
The exam is composed of 50 questions with a 90 minutes duration and with a minimum passing score of 68%.
The main topics tested in the exam include:
- Working with Java data types.
- Controlling Program Flow
- Java Object-Oriented Approach
- Exception Handling
- Arrays and Collections
- Streams and Lambda expressions
- Java Platform Module System
- Concurrency
- Java I/O API
- Secure Coding in Java SE Application
- Database Applications with JDBC
- Localization
- Annotations
I enjoyed studying for this exam as it allowed me to deepen my knowledge on some aspects of the java language that I don’t use often at work. In particular, I enjoyed the most studying about Java Platform Module System (JPMS) that was introduced with Java version 9, Streams, Lambads expressions and secure coding.
For the exam preparation, I highly recommend the following books Java SE 11 OCP complete study guide and Java 11 SE OCP practice tests. The first book cover all the theorical concepts required for the exam and the second one is composed of a lot of exercises and practice tests that prepare you very well for the exam questions.
