NetBeans functionality mediation for extending modules

In the initial courses of programming languages student tend to encounter many difficulties. One of the way how the learning process can be facilitated is by using an appropriate IDE. Unfortunately there are not many appropriate tools available and even fewer of them are freeware. Among all these tools BlueJ is considered to be a prominent one. This is proved by the fact that it is applied at nearly one thousand universities all over the world. Nevertheless, the problem we have to deal with when teaching programming with BlueJ is that it is oversimplified. Sooner or later the students that take programming seriously have to trade this IDE for something more professional. The transition is not always an easy one. Some sources even state that the difficultness of the transition is comparable (or equal) to the difficultness of learning a new programming language. The bachelor thesis originates in an idea to teach students programming with a professional IDE right from the beginning. To make it possible, we have to find a suitable professional IDE. Unfortunately, as far as we know there is none around that would fit our needs/requirements. The only reasonable solution in the current situation seems to be to modi-fy an existing one. As an IDE to be modified the application called NetBeans IDE was cho-sen. The goal of this thesis was to analyze the structure of the NetBeans IDE, find out how one can extend its functionality, design and implement an API that would allow querying information about internal structure of java projects, making changes to the structure of the code and integrating new functionality in to the IDE. The goals that were set were successfully reached and the thesis represents a report of the process of analysis and implementation
