The Basics. Every AP exam question uses at least one of these: • Types and Identifiers
• Operators
• Control structures
Objects, Classes, and Inheritance. You may have to write your own class. You’ll definitely need to interpret at least one class that’s given.
• Methods
• Subclasses
• Abstract classes • Interfaces
