Outcomes
  • Write and trace Java programs using AP CSA language features and standard library expectations.
  • Design classes with constructors, fields, methods, encapsulation, and clean object state.
  • Prepare for AP-style multiple choice and free-response code writing without copying official prompts.

Unit sequence

Built for independent progress first, then tutor support where the student gets stuck.

  1. 01

    Java objects, primitives, and expressions

    • Use int, double, boolean, String, objects, constructors, and methods.
    • Trace expression evaluation, assignment, and method calls.

    Practice: Write small Java snippets that create objects, call methods, and explain every resulting value.

  2. 02

    Selection and Boolean logic

    • Use if, else-if, else, relational operators, and compound Boolean expressions.
    • Trace branching code and identify equivalent conditions.

    Practice: Implement a decision function with tests for boundary, normal, and invalid inputs.

  3. 03

    Iteration and string algorithms

    • Use while and for loops with counters, sentinels, and accumulators.
    • Write standard String traversal and transformation algorithms.

    Practice: Build and trace a loop-based String analyzer with tabled variable values.

  4. 04

    Class creation and encapsulation

    • Design fields, constructors, accessors, mutators, and instance methods.
    • Use private state and public behavior deliberately.

    Practice: Create a simple class with valid starting state, methods, and object-level tests.
