Welcome to Lecture 18 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, I walk you through the step-by-step implementation of a music player application—think Spotify—using core object-oriented design patterns: Facade, Singleton, Adapter, and Strategy. We will learn: - Defining Problem Statement - Complete UML Diagram for Music Player Application - Interview Standard Code walk through in C++ and source code also available in Java. - 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/0029Va6H0tbHVvTbcuT99Y1f Code and Notes: Github : https://github.com/adityatandon15/LLD Connect with Aditya Tandon Instagram : https://www.instagram.com/adityatandon2 LinkedIn : https://www.linkedin.com/in/adityatandon2 Twitter : https://x.com/adityatandon02 00:00 Introduction 00:59 Requirements gathering 03:21 Happy Flow 07:06 UML Design for Music Player 52:00 Full UML Diagram 53:07 Code for Music Player App 01:13:16 Conclusions and Further Extensions #SystemDesign #LowLevelDesign #LLD #AdapterPattern #DesignPatterns #Cplusplus #JavaDevelopers #UMLDiagrams #TechInterviews #SoftwareEngineering #XMLtoJSON #CleanCode #SoftwareArchitecture #ObjectOrientedDesign #CodingWithExamples #CodeBetter #8WeeksLLDChallenge #JSON
