  • Methods, parameters, and return values
  • Object-oriented programming: classes, objects, inheritance, and interfaces
  • Arrays and core collections like ArrayList and HashMap
  • Exception handling and structured debugging
  • Organizing and writing multi-class programs
  • Introduction to basic data structures and algorithms
  • Project-based practice aligned with AP CS A topics

Who this course is for

A strong fit for students currently in or preparing for AP Computer Science A, as well as anyone who wants a rigorous introduction to object-oriented programming. Some prior coding exposure is helpful but not required.
