AP CSA Unit 3: Class Creation focuses on abstraction, program design, and creating and using Java classes. You will learn how classes define objects, how constructors initialize objects, how methods operate on data, and how object references, class variables, methods, and scope affect program behavior.
This page is the central hub for AP CSA Unit 3 MCQ Practice. The topics below follow the current College Board AP Computer Science A course framework. Topic-specific practice sets will be added as they are developed.
Study strategy: Build a strong understanding of classes, objects, constructors, methods, references, class members, and scope before attempting mixed Unit 3 MCQ practice.
Abstraction & Program Design
Abstraction and Program Design
Understand abstraction and program design, including how abstractions can help organize programs and solve problems.
Coming SoonImpact of Program Design
Explore how program design and computing can affect society, the economy, and culture, including considerations related to programs and programmers.
Coming SoonClasses & Constructors
Anatomy of a Class
Practice identifying the components of a Java class, including instance variables, methods, parameters, and other elements of a class definition.
Coming SoonConstructors
Understand how constructors initialize objects and how constructors with parameters can be used when creating objects from a class.
Coming SoonWriting Methods
Methods: How to Write Them
Practice writing and tracing Java methods, including parameters, return values, method calls, and the behavior of methods within a class.
Coming SoonObject References
Passing and Returning Object References
Understand how object references are passed to methods and returned from methods, and how changes to objects can affect program behavior.
Coming SoonClass Variables, Methods & Scope
Class Variables and Class Methods
Practice understanding class variables and class methods,
including how static members belong to the class
rather than to individual objects.
Scope and Access
Understand variable scope and access within Java classes, methods, constructors, and blocks, including the role of access modifiers.
