In the course Advanced Java Programming a series of advanced aspects of Java are discussed. The course covers the topics that are asked for on the Oracle Certified Java Professional or OCP exam and is a good preparation to pass this exam.
In the first place attention is paid to aspects of Advanced Class Design such as the implementation of inheritance and composition, the use of polymorphism, interfaces, inner and anonymous classes and the singleton pattern.
Next multithreaded applications are discussed and the synchronization between threads when accessing shared data. During the treatment of the concurrency package advanced synchronization mechanisms such as cyclic barriers and countdown latches are discussed.
Also the functional language constructs introduced in recent Java versions are discussed with lambdas and functional interfaces.
Next generics are on the course program with which classes and methods can be parameterized, strong typing is imposed and the chance of runtime errors is limited. Generics are used a lot in the Collection Framework and the most important container classes in this Framework are discussed.
Next attention is paid to the Stream API that enables transformations on data collections to be performed by a combination of successive simpler methods like map and reduce.
The various possibilities for dealing with errors and exceptions are also on the program and attention is paid to file I/O and new I/O when accessing files and directories.
Database access with Java Database Connectivity (JDBC) is treated and queries, prepared statements and transactions are part of that.
Finally, if time permits, reflection is optionally on the course program, with which compiled Java classes can be analyzed by means of software, and optionally various aspects of enhancing the Java performance are discussed.
The course Advanced Java Programming is intended for experienced Java developers who want to gain more in depth knowledge of Java.
Knowledge of the Java language and syntax and basic experience in Java programming is required to participate in this course.
The theory is treated on the basis of presentations and is interspersed with exercises. Demos are used to clarify the theory. The course material is in English. The course times are from 9.30 up and to 16.30.
Participants receive an official certificate Advanced Java Programming after successful completion of the course.
