The editor highlights the components of the source code in various colors and provides an autocompletion function as you type ( Figure 3). Greenfoot is based on the BlueJ Java development environment from which it inherits some of its functions. You need to interpret the created programs before running them, but that's easily done with a single mouse click on the user interface.įigure 3: The Greenfoot editor provides not only syntax highlighting but also thumbnails on the right with which you can quickly navigate to desired code locations. The tutorials on the Greenfoot web page are only partially explained, so a Java book is a must. Unlike Alice, these actions are done through direct input of Java code.

As a rule, each object is a visible entity in a virtual world ( Figure 3) that students rotate, scale, and otherwise alter through prepared methods. Greenfoot programming is done in Java, with the development environment providing pre-built classes or objects. Targeted at secondary students from about 14 years of age, development of Greenfoot began back in 2003, with the tool under GPL starting in 2009. This joint venture between the University of Kent and La Trobe University in Australia for a development learning environment allows rapid creation of two-dimensional graphics applications – in particular simulations and games. Greenfoot seeks to provide the first entry into Java object-oriented programming.
