Greenfoot is a software environment that allows users to manipulate 2D graphics and sound using code from Java, an object oriented language. It is typically used to create and run simple games.
A computer cannot understand Java code so whenever a programmer makes any alterations to the program, the code needs to be translated (compiled) into machine code to be understood and executed by the computer. In later versions of Greenfoot, this automatically happens whenever changes are detected. In earlier versions, the programmer needs to click on the ‘Compile’ button to do this.
Programming Greenfoot is needed for your Unit 2 exam but you also need to know terminology and understand the concepts which could arise in Unit1 or 2 exam.
Follow the tutorials to upskill yourself in Greenfoot and use the theory guide to understand the concepts.
