Facade Design Pattern | Real-world use case + Code | Design patterns in LLD

Welcome to Lecture 17 of the Ultimate Low-Level Design (LLD) Series by Coder Army! fourth week for #lowleveldesign #systemdesign #8weeksLLdchallenge. We are doing 8 weeks challenge and going to complete the whole course within the duration with quality content on Youtube. Let’s learn LLD like never before and attain advance level mastery on this subject. In this video, we dive deep into the Adapter Design Pattern by solving a real‐world problem: consuming a third‐party data provider that returns XML, and exposing it in our application as JSON. You’ll learn: In this video, we explore the Facade Design Pattern through a real‐world example: booting up a computer. Instead of making the client interact with each subsystem (power supply, cooling, BIOS, hard drive, OS), we introduce a single ComputerFacade class that wraps them all. You’ll see: How subsystems like PowerSupply, CoolingSystem, BIOS, etc., work together Why a Facade unifies those calls into one simple startComputer() method The UML diagram illustrating the Facade’s relationships A clean C++/Java implementation ready to use as a template for your projects Whether you’re building a media player, a home automation controller, or any multi‐component system, the Facade Pattern keeps your code clean and your clients happy. Perfect for: Beginners in System Design Students preparing for LLD interviews Developers looking to solidify design pattern concepts in real-world use Join Coder Army Whatsapp Group: https://whatsapp.com/channel/0029Va6H...
