Greenfoot 3.5.4

Create an integrated development environment for building Java-based simulations for graphical programs and games using the standard code and visualization options to access large amounts of documentation simultaneously. The suite features an image library with categories such as ‘animals’, ‘buildings’, ‘objects’, ‘people’, ‘symbols’, etc.

Greenfoot 1.4.6 is a framework and an integrated Java development environment.

As a framework, you can use it for creating two-dimensional grid assignments in Java. As an integrated development environment (class browser, editor, compiler, execution, etc.) it´s also suitable for novice programmers.

Greenfoot 1.4.6 supports the full Java language, but it is especially useful for programming those exercises having a visual element. In this environment, object visualisation and interaction are the key elements.

In order to use Greenfoot 1.4.6, you must have JDK (Java Development Kit) 1.5 or later installed.

If you don´t have JDK, you can download the Java SE Development Kit 6u11 from the Java site at http://java.sun.com/javase/downloads/index.jsp.

To become familiar with Greenfoot, you can see the tutorial that the program offers.

Once Greenfoot has started, load the Wombats scenario.

You will then be able to add bears and leaves in the grid. In that way, you will be building a Java game, graphically. Once you are finished, you can compile the classes and save the result.
