- Class, object (and the difference between the two)
- Instantiation
- Method (as opposed to, say, a C function)
- Static methods and classes
- Destructor/finalizer
- Inheritance
- Encapsulation
- Multiple inheritance (and give an example)
- Abstract class
- Interface/protocol (and different from abstract class)
- Method overriding
- Method overloading (and difference from overriding)
- Polymorphism (without resorting to examples)
- Method visibility (e.g. public/private/other)
