If you are interested in computer programming, the NetBeans will be ideal for you. NetBeans is a socalled IDE, or 'Integrated Development Enviroment', and you can use netBeans to program in Java, C/C++, PHP and Ruby.
In Java you can make regular Java-programs, or you can make Java Applets, small programs that you can run in a web browser. Java games and programs are also very popular on mobile platforms, like for instance your mobile phone. With NetBeans you can also create your active web-page with JavaScript.
