Training for people who want to learn how to design and build applications using Java.

During the training, participants will learn about the language syntax and selected Java classes as well as the concepts of object oriented programming and their practical use. They will also acquire the ability to independently solve problems using the available documentation during the process of creating applications in Java. The presented material largely covers the scope of knowledge required for the OCAJP exam (Programmer I).

Knowledge of the Windows environment. Having experience in programming in another object or structural language is an additional asset that facilitates the acquisition of knowledge.
