In the course Java Certification participants are prepared for the Java OCA (Oracle Certified Associate) and OCP (Oracle Certified Professional) exam.
The course is an exam training in which the central focus is on the questions that can be asked on these exams. On the basis of test questions and test exams, the subjects that are part of the exams are treated.
Special attention is paid to topics that are often considered difficult such as concurrency and synchronization. As well as to features that have been added in later versions of Java such as lambda's and streams.
Also discussed are generics, collection classes, database access with JDBC and new I/O. Subjects like declarations and access control, object orientation, assignments and operators, flow control, exceptions and assertions, strings, I/O formatting and parsing, inner classes are also on the program.
Depending on the interest of the participants certain components can be treated with more depth if so desired.
The course Java Certification is intended for experienced Java developers who want to prepare themselves for the Java 8 programmer exams OCA (Oracle Certified Assciate) and OCP (Oracle Certified Professional).
To participate in this course knowledge of and ample experience with object oriented concepts and Java programming is required.
The course is an exam training in which, apart from theory and demos, various test exams with test questions for the exams are discussed. The theory is interspersed with practical exercises. The course material is in English. The course times are from 9.30 am to 16.30 pm.
After successful completion of the course attendants receive an official certificate of participation in the Java Certification course.
