![]() You can derive your own subclasses from these two classes and apply methods to them in Java code. Double-clicking a class opens its Java code in an editor.įigure 4: Greenfoot's main window shows a playing field with two objects of type Wombat and two of type Leaf.Ĭlasses, which correspond to a square on the screen, and ActorĬlasses, which are graphical objects in the virtual world. On the right is a simple class diagram to help you see the class relationship. The main window then opens with the outlines of a program ( Figure 4). Once started, you first create a new scenario. ![]() For other distributions, you have to go to an installation package that you start with java -jar Greenfoot-generic-221.jar The Greenfoot developers make binaries available as DEB packages for Ubuntu and Debian. ![]() Additionally, projects can easily transfer to other IDEs, with the "naked" Java code residing in the project directory. Basically, all options are open to you, and you can even add external Java libraries. Because Greenfoot programming is done directly in Java, you can very easily develop programs further. You can record music and sounds with a built-in sound recorder or import MP3 files. 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. ![]() We will only watch 25 minutes of the 60 minute video.Greenfoot seeks to provide the first entry into Java object-oriented programming.
