GridWorld Case Study

The current AP Computer Science A case study is GridWorld. Questions relating to this case study will appear on the AP Computer Science A Exams.
 
The GridWorld case study provides a graphical environment in which students can experiment with different types of objects and observe how programming changes will affect the behavior of those objects. It is  a required part of the AP Computer Science A curriculum. Computer Science A students are expected to be familiar with the material in Parts 1–4 of the case study narrative.

You are encouraged to attend a College Board workshop to learn more about this case study. Questions about the case study should be addressed to the AP Computer Science Electronic Discussion Group.

The case study consists of a narrative and a zip file containing the program code and documentation. There are three folders in the zip file: the framework folder that contains the black box code for the graphical environment; the projects folder that contains code for which students are responsible; and the javadoc folder that contains the documentation for GridWorld. The index file in the javadoc folder can be used as a starting point for viewing the documentation.

Please note that if you have a version watermark such as “0.96” displayed in your output window, you do NOT have the final version of the code installed. To correct this problem, download this Zip File and follow the instructions in the Installation Guide, being sure to install the current version of the jar file.
