Unit 2: Using Objects

You’ll explore reference data as a way to represent real-world objects in a digital world and discover methods to perform more complex operations.

Topics may include:

  • Objects and classes as ways to describe instances, attributes, and behaviors
  • Creating objects by calling constructors with and without parameters
  • Utilizing class libraries, including Integer and Double
  • Defining an object’s behavior using methods, including static and Math class

Topics may include:

  • Creating a loop to run an expression repeatedly until certain conditions are met
  • Standard arithmetic-based and String algorithms
  • Representing iterative processes in code using for and while loops
  • Nesting loop and iteration statements

On The Exam

17.5%–22.5% of exam score

Unit 5: Writing Classes

You’ll explore how real-world interactions can be expressed digitally by organizing behaviors and attributes into classes, and you’ll examine the legal and ethical implications of computer programming.

Topics may include:

  • The makeup of a class, including whether attributes are public or private
  • Setting an object’s attributes using constructors
  • Using comments to describe the functionality of code
  • Defining behaviors of an object using non-void, void, and static methods
  • Where variables can be used in program code
  • Breaking problems into smaller parts by creating methods to solve individual subproblems
  • Intellectual property and ethical concerns in programming

On The Exam

5%–7.5% of exam score

Unit 6: Array

You’ll learn techniques and standard algorithms to work with collections of related data, known as data structures.

Topics may include:

  • Representing multiple related items as array objects
  • Traversing an array by accessing the elements using iteration statements
  • Standard algorithms that utilize array traversals to perform functions

On The Exam

10%–15% of exam score

Unit 7: ArrayList

You’ll delve deeper into data sets, exploring ArrayList objects for larger amounts of data, as well as the privacy concerns related to personal data storage.

Topics may include:

  • Representing collections of related object reference data using ArrayList objects
  • Traversing an ArrayList by accessing the elements using iteration statements
  • Standard algorithms that utilize ArrayList traversals to perform functions
  • Searching and sorting using standard algorithms
  • Ethical issues around data collections

On The Exam

2.5%–7.5% of exam score

Unit 8: 2D Array

Now that you’ve explored 1D arrays, you’ll branch out into 2D arrays and experiment with data sets represented in a table.

Topics may include:

  • Representing collections of data as arrays of arrays, or 2D arrays
  • Traversing a 2D array by accessing the elements using nested iteration statements

On The Exam

7.5%–10% of exam score

Unit 9: Inheritance

You’ll learn how to manipulate programming without altering existing code by using subclasses to create a hierarchy.

Topics may include:

  • Using common attributes and behaviors to group existing objects into superclasses
  • Defining and overriding methods within subclasses and superclasses
  • Creating references using inheritance hierarchies
  • Associating subclass objects with superclasses to create polymorphism

On The Exam

5%–10% of exam score

Unit 10: Recursion

You’ll work on solving larger problems by solving smaller, simpler versions of the same problem using recursive methods.

Topics may include:

  • Executing recursive methods
  • Searching and sorting using binary search and merge sort algorithms

On The Exam

5%–7.5% of exam score
