New Java language elements

The aim of the training is to master Java language tools and to become familiar with the Java API. The tools used will be introduced, such as JDK, IntelliJ IDEA, Maven, and Git, as well as the most important language elements and classes.

The training includes numerous practical exercises; to implement these, we use the IntelliJ IDEA development environment in Maven-based projects, together with the JUnit unit testing framework.

The training is enhanced with complex project tasks.

Knowledge of algorithms and programming fundamentals (variables, functions, parameters, return values, control structures – conditionals and loops) in any programming language.

Since part of the training materials is in English, basic English skills at the level of reading documentation are required. The videos are in Hungarian, based on Hungarian-language slides.
