Solution and notes A-4 This question involves a simple algorithm for moving a “robot” along a one-dimensional array. Archived from the original on Sp 9, Instead of the discontinued case studies, the College Board ap computer science case study answers three new labs that instructors are invited to use, but they are optional and are not tested on the exam.

What does the this refer to after the constructor?? Case studies were used in AP Computer Science curriculum starting in This question is a Marine Biology Simulation case study question.

Reply Brandon Horn Mar 5, This question involves a priority queue implemented as ap computer science case study answers binary search tree with TreeNode nodes. In both cases, this could be omitted and the result would be the same.

The free-response questions are posted on The College Board’s web site: Retrieved 22 February It served as an example of object-oriented programming OOP embedded in a more complicated design project than most students had worked with before. Solution and notes A-2 This question involves a small hierarchy of classes, calling constructors and methods of the superclass, and traversing an ArrayList.

Retrieved from ” https: These programs were called Case Studies. Retrieved 27 October This question involves a small hierarchy of classes, calling constructors and methods of the superclass, and traversing an ArrayList. It involves counting and adding fish in a bounded environment.

Archived from the original on There are no question on the specific content of the labs on the AP exam, but there are questions that test the concepts developed in the labs. Retrieved 28 February Solution and ap computer science case study answers AB-4 This question involves a priority queue implemented as a binary search tree with TreeNode nodes.

The three labs are: Each location is constructed using row and column values not known to be valid in the grid.

Run getColor before and after act and check the return value. Thanks for this but I am still confused, every time I try to run this it computter changes the color unless courage is 0?

Students were expected to be familiar with the classes and interfaces and casr they interact before taking the exam. The GridWorld Case Study was used as a substitute for writing a single large program as a culminating project. Accessed September 15, There were also five multiple-choice questions that are derived from the case study.

This practice was discontinued as of the school year and replaced ap computer science case study answers optional labs that teach concepts.

Reply Brandon Horn Mar 26, 6: This page was last edited on 23 Octoberat AP Computer Science A emphasizes object-oriented programming ap computer science case study answers with an emphasis on problem solving and algorithm development. The Big Integer case study was in use ap computer science case study answers to It also includes the study of data structures and abstraction, but these topics were not covered to the extent that they were covered in AP Computer Science AB.

The case study was designed to allow the College Board to quickly test a student’s knowledge of object oriented programming ideas such as inheritance and encapsulation while requiring students to understand how objects such as “the environment”, “the fish”, and the simulation’s control module interact with each other without having to develop the entire environment independently, which would be quite time consuming.
