Correlated to: AP Computer Science AB Topic Outline

Note: Only the sublevels of each topic are listed with sections.

I. Object Oriented Program Design

A. Program Design
1. Read and understand a problem description, purpose, and goals. Specify the purpose and goals for a problem 1.7, 2.5, Program Assignments throughout, Definitions of every data structure and example throughout
2. Apply data abstraction and encapsulation 2.2, 2.4, 2.5, 2.6
3. Read and understand class specifications and relationships among the classes. (is-a, has-a relationships) Decompose a problem into classes; define relationships and responsibilities of those classes 2.5, 2.6, 2.7, 2.8, 2.9, 2.10, 2.12, 2.13, 2.14, program assignments throughout
4. Understand and implement a given class hierarchy 2.1, 2.2, 2.13, 2.14, 2.15
5. Identify reusable components from existing code using classes and class libraries 2.3, 2.11, 2.13
B. Class Design
1. Design and implement a class. Design and implement a set of interacting classes 2.5, 3.3, Each data structure contains an example of how that structure would be used in a larger scenario involving many interacting classes
2. Design an interface 3.1, 3.2, Interfaces are addressed in every chapter that introduces a new data structure
3. Choose appropriate data representation and algorithms. Choose appropriate advanced data structures and algorithms Each data structure chapter discusses the differences between implementations based upon different data representation (See 8.4, 8.5, 8.6 for example)
4. Apply functional decomposition 3.4, every data structure implementation
5. Extend a given class using inheritance 2.12, 2.13, 2.14, 9.7

II. Program Implementation

A. Implementation techniques
1. Methodology (object oriented development, top down development, encapsulation and information hiding, procedural abstraction) 1.3, 1.7, 2.1, 2.2, 2.6, 2.10
2. Programming constructs (Primative types vs. objects, declaration of constants, variables, classes, interfaces, methods, parameters) Appendix A (Basic concept review)
3. Console output Appendix A, 2.2
4. Control (Methods, sequential, conditional, iteration, recursion) Appendix A, 2.4, 6.1, 6.2, 6.3
C. Java library classes included in A and AB AP Java Subset Appendix B, 3.1, 10.6, 12.5

III. Program Analysis

A. Testing
1. Test classes and libraries in isolation 1.2, Introduction of each data structure

3. Perform integration testing 1.2, Use of each data structure in another program, various programming problems
B. Debugging
1. Categoize Errors 1.2
2. Identify and Correct Errors 1.2
3. Techniques: use a debugger, add extra output statements, hand trace code Various programming problems
C. Understand and modify existing code Various programming problems, Case Study supplement
D. Extend existing code using inheritance 2.12, 9.7, Case Study Supplement
E. Understand Error Handling (understanding runtime exceptions, throw runtime exceptions) 2.15, 3.2, Introduction of exceptions for each data structure
