====GridWorld case study (2008-2014)====

'''GridWorld''' is a computer program case study written in [[Java (programming language)|Java]] that was used with the [[AP Computer Science]] program from 2008 to 2014.<ref>Horstmann, Cay. [http://gridworld.info/ "GridWorld".] ''horstmann.com''. Accessed September 15, 2008.</ref> It serves as an example of [[object-oriented programming]] (OOP). GridWorld succeeded the [[Advanced Placement Computer Science#Marine Biology Case Study|Marine Biology Simulation Case Study]], which was used from 2000–2007. The GridWorld framework was designed and implemented by [http://horstmann.com Cay Horstmann], based on the Marine Biology Simulation Case Study. The narrative was produced by Chris Nevison and Barbara Cloud Wells, [[Colgate University]].

The [[GridWorld]] Case Study was used as a substitute for writing a single large program as a culminating project. Due to obvious time restraints during the exam, the GridWorld Case Study was provided by the College Board <!-- commented out direct link just in case it can be used as a reference in the future [http://apcentral.collegeboard.com/apc/public/repository/GridWorldCode.zip]--> to students prior to the exam. Students were expected to be familiar with the classes and interfaces (and how they interact) before taking the exam. The case study was divided into five sections, the last of which was only tested on the AB exam. Roughly five multiple-choice questions in Section I were devoted to the GridWorld Case Study, and it was the topic of one free response question in Section II.
