Object-Oriented Programming for MAANG Interviews

A book-shaped table of contents for OOP: paradigm foundations, the four pillars, object relationships, SOLID/GRASP design principles, memory and runtime internals, GoF design patterns, language-specific OOP, and OOP at system scale — cross-linking existing pattern, concurrency, and low-level-design notes instead of duplicating them.

1 — Association

Distinguishes One-to-One, One-to-Many, and Many-to-Many as the core sub-topics of association.

3 — Composition

Distinguishes Strong Ownership, Lifecycle Dependency, and Composition over Inheritance as the core sub-topics of composition.

4 — Dependency

Distinguishes Uses-A Relationship, Constructor Injection, Method Injection, and Dependency Graph as the core sub-topics of dependency.
