AP Computer Science A: 8-Week Exam Review provides a comprehensive review of essential Java programming concepts and prepares students for the AP Computer Science A exam. Through hands-on exercises and targeted instruction, students will solidify their understanding of object-oriented programming, data structures, and algorithms, enabling them to confidently tackle both multiple-choice and free-response questions on the exam.

Java Fundamentals

• Primitive data types (int, double, boolean) — including their characteristics and appropriate usage
• Variables, operators, and expressions — mastering the building blocks of Java syntax
• Control flow statements (if/else, loops) — implementing decision-making and iteration in code

Object-Oriented Programming

• Classes and objects — defining blueprints and creating instances with attributes and behaviors
• Methods — designing reusable code blocks that perform specific actions within a class
• Constructors — initializing objects and ensuring proper object state upon creation
• Encapsulation — bundling data and methods within a class to protect data integrity

Strings and the Math Class

• String manipulation — using built-in methods for searching, extracting, and modifying text
• The Math class — leveraging mathematical functions like abs(), sqrt(), and pow()
• Random number generation — utilizing Math.random() to simulate events and create dynamic behavior
• Scaling and truncating random numbers — generating random integers within specific ranges

Arrays and ArrayLists

• One-dimensional arrays — storing and accessing collections of elements of the same data type
• ArrayLists — utilizing dynamic arrays that automatically resize as needed
• Array traversal — efficiently iterating through arrays using loops
• Common array algorithms — searching, sorting, insertion, deletion, and reversal
• Two-dimensional arrays — representing tables of data and performing operations on rows and columns

Searching and Sorting Algorithms

• Selection sort — understanding the step-by-step process of this in-place comparison sort
• Algorithm analysis — recognizing the characteristics and efficiency of different sorting approaches

Exam Preparation

• Multiple-choice strategies — approaching different question types and eliminating incorrect answers
• Free-response question techniques — planning, coding, and debugging solutions within time constraints
• Code analysis — interpreting code snippets and predicting their behavior
• Practice questions — working through realistic exam-style problems to build confidence and refine skills
