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 — Encapsulation

Explains Information Hiding, Data Protection, Getters & Setters, Immutable Objects, and Defensive Copying as the core sub-topics of encapsulation.

2 — Abstraction

Explains Interfaces, Abstract Classes, APIs, Implementation Hiding, and Domain Modeling as the core sub-topics of abstraction.

3 — Inheritance

Explains IS-A Relationship, Base Classes, Derived Classes, Method Overriding, Constructor Chaining, Multiple Inheritance, and Diamond Problem as the core sub-topics of inheritance.
