HIGH-YIELD REVISION GUIDE & CHEAT SHEET
Object-Oriented Programming & Design
Patterns Complete Semester Guide
High-Yield Comprehensive Guide, vtable Memory Layouts, SOLID Refactoring
Traces, GoF Implementations & Quick-Cram Appendix
Computer Science & Software Architecture | Course Code: University Of California - Berkeley
- CS 61B / CS 108 | 2024-2025 Comprehensive Edition
📘 WHAT’S INSIDE THIS GUIDE:
✔ Core OOP Invariants: Encapsulation boundaries, Abstraction, Polymorphism, and why Compo-
sition beats Inheritance
✔ Dynamic Dispatch Mechanics: Virtual Method Tables (vtable), object vptr layout, and indirect
function pointer dispatch
✔ WORKED STEP-BY-STEP PROBLEM: Step-by-step refactoring of an anti-pattern God Class
into SOLID Strategy & Dependency Injection
✔ Creational & Structural Patterns: Thread-safe double-checked locking Singleton, Factory
Method, Adapter, and Decorator
✔ Behavioral Design Suite: Strategy, Observer (Pub/Sub with weak references), Command (Undo/
Redo stack), and State machines
✔ Software Architecture Smells: Fragile Base Class problem, Feature Envy, Primitive Obsession,
and Circular Dependencies
✔ 10 Deadly OOP Exam Traps (Liskov precondition/postcondition strengthening rules, shallow
vs. deep copies, static dispatch)
✔ APPENDIX: 1-Hour Emergency Pre-Exam Quick-Cram Cheat Sheet with master GoF pattern
table and 25 active recall flashcards
