Course material from the practical sessions I teach at Eötvös Loránd University, Faculty of Informatics – rewritten as study pages: what each session is about, the ideas behind it in diagrams, and how they apply to your assignment or team project.

Open a session on the course page, or open it on its own in a new tab. Requirements are listed without dates; the current deadlines are always on Canvas.

- Programozási technológia
  
  ## Programming Technology
  
  Java from object-oriented recap to complete GUI games: collections, files and exceptions, Swing, model–view separation, graphics, animation and a database-backed leaderboard.

- Szoftvertechnológia
  
  ## Software Technology
  
  Teams of three (at most four) build the semester’s game – every team the same one – through four milestones: requirements and design, then three prototypes – with GitLab issues, feature branches, merge requests, CI, unit tests and code review the way industry teams use them.
