1. Foundations

Classes & Objects: Blueprint and instance, constructors, fields, methods, and the 'new' keyword.
Inheritance: IS-A relationship, superclass/subclass, method overriding, and virtual dispatch.
Polymorphism: Compile-time (overloading) vs runtime (overriding), subtype polymorphism, and interfaces.

Encapsulation: Data hiding, access modifiers (public, private, protected), getters/setters, and invariants.
Abstraction: Abstract classes, interfaces, information hiding, and contract-based design.
Composition: HAS-A relationship, object composition, aggregation, and favoring composition over inheritance.

SOLID Principles: Single responsibility, open/closed, Liskov substitution, interface segregation, dependency inversion.
