AP CS A

1. Program Design

   Anotações:

   • 1. Read and understand a problem description, purpose, and goals. 2. Apply data abstraction and encapsulation. 3. Read and understand class specifications and relationships among the classes (“is-a,” “has-a” relationships). 4. Understand and implement a given class hierarchy. 5. Identify reusable components from existing code using classes and class libraries.
2. Class Design

   Anotações:

   • 1. Design and implement a class. 2. Choose appropriate data representation and algorithms. 3. Apply functional decomposition. 4. Extend a given class using inheritance.

1. Programming constructs
   1. Primitive types vs. objects
   2. Declaration

      Anotações:

      • a. Constant declarations b. Variable declarations c. Class declarations d. Interface declarations e. Method declarations f. Parameter declarations
   3. Console output (System.out.print/println)
   4. Control

      Anotações:

      • a. Methods b. Sequential c. Conditional d. Iteration e. Understand and evaluate recursive methods
2. Implementation Techniques
   1. Methodology

      Anotações:

      • a. Object-oriented development b. Top-down development c. Encapsulation and information hiding d. Procedural abstraction
3. Java library classes (included in the AP Java subset)

1. Debugging

   Anotações:

   • 1. Categorize errors: compile-time, run-time, logic. 2. Identify and correct errors. 3. Employ techniques such as using a debugger, adding extra output statements,
2. Understand and modify existing code
3. Extend existing code using inheritance
4. Understand error handling

   Anotações:

   • Understand runtime exceptions
5. Reason about prograing

   Anotações:

   • 1. Pre- and post-conditions 2. Assertions
6. Analysis of algorithms

   Anotações:

   • 1. Informal comparisons of running times 2. Exact calculation of statement execution counts
7. Numerical representations and limits

   Anotações:

   • 1. Representations of numbers in different bases 2. Limitations of finite representations (e.g., integer bounds, imprecision of floating-point representations, and round-off error)
8. Testing

   Anotações:

   •  Testing 1. Test classes and libraries in isolation. 2. Identify boundary cases and generate appropriate test data. 3. Perform integration testing.

Anotações:

• Data structures are used to represent information within a program. Abstraction is an important theme in the development and application of data structures.

1. Simple Data Types

   Anotações:

   • int, boolean
2. Classes
3. Lists
4. Arrays

Anotações:

• Standard algorithms serve as examples of good solutions to standard problems. Many are intertwined with standard data structures. These algorithms provide examples for analysis of program efficiency.

1. Operations on Data Structures

   Anotações:

   • 1. Traversals 2. Insertions 3. Deletions
2. Searching

   Anotações:

   • 1. Sequential 2. Binary
3. Sorting

   Anotações:

   • 1. Selection 2. Insertion 3. Mergesort

Anotações:

• An awareness of the ethical and social implications of computing systems is necessary for the study of computer science. These topics need not be addressed in detail but should be considered throughout the course.

1. System reliability
2. Privacy
3. Legal issues and intellectual property
4. Social and ethical ramifications of computer use
