Introductory phase (EF): In the early stages of teaching computer science in the EF there are different approaches eg with Greenfoot. Here I will but introduce projects realized with Netbeans. the first projects deal with simple graphics and string manipulations. Based on the graphic examples, an entrance to the object-oriented programming (ball as moving circle, billiard ball subclass of ball knows a pool table, circle and square as a subclass of the abstract class figure, polymorphism, etc.).

Qualifying phase I (Q1): A first project deals with recursive algorithms, then various projects follow on "Linear Data Structures" (List, Stack, Queue) and on the theme of "Searching and Sorting". Finally, projects are being implemented to tree structures.

Qualification Phase II (Q2): Here various projects for client / server programming are presented.
