Flipkart LLD Round: Stack Overflow Clone - Complete Java Code Implementation | Part 2

Welcome to Part 2! Time to bring our Stack Overflow design to life with complete Java implementation. This is the EXACT code that can help you crack Flipkart's machine coding round! 🎯 What You'll See in Part 2: ✅ Complete Java code implementation from scratch ✅ All design patterns in action (Strategy, Factory, Observer) ✅ Working demo with multiple test cases ✅ Proper error handling and validations ✅ Clean, modular, and extensible code structure ✅ Driver class with comprehensive testing ✅ Concurrent request handling ✅ In-memory data storage implementation 🏗️ Code Structure Covered: Model classes (User, Topic, Question, Answer, Post) Service layer (AuthService, UserService, PostService, FeedService) Enums and Constants (FilterType, PostType, QuestionStatus) Design Patterns implementation Exception handling Data storage with Maps and Lists 💡 Key Features Implemented: User signup, login, logout Topic subscription/unsubscription Question posting with multiple topics Answer system with acceptance mechanism Upvoting system for questions and answers Advanced feed filtering (topic-based, status-based) User profile management Question details view 🔥 Design Patterns in Action: *Strategy Pattern:* Feed filtering logic *Factory Pattern:* Post creation (Question/Answer) *Observer Pattern:* Notification system *Decorator Pattern:* Advanced filtering Github: https://github.com/deeppatel23/Youtub... 📋 Features Demonstrated: Multiple users interacting simultaneously Complex filtering scenarios Edge case handling Error scenarios and validations Real-world usage patterns 💼 Perfect for: Machine coding round preparation Learning practical design pattern implementation Understanding clean code architecture System design interview practice Java developers wanting to improve code quality 🔧 Technologies Used: Core Java (Collections, OOP concepts) Design Patterns In-memory data structures Exception handling Multithreading concepts 📝 Code Available: GitHub link in comments (star the repo!) All files organized and well-documented Ready to run and test 🔔 What's Next? Advanced features implementation Database integration version Microservices architecture approach Performance optimization techniques 🏆 This implementation follows industry best practices and can be directly used in coding interviews! 💬 Drop your questions in comments - I'll personally answer each one! #JavaImplementation #LowLevelDesign #StackOverflow #FlipkartInterview #DesignPatterns #JavaCode Core Implementation & Code: #JavaImplementation #JavaCode #JavaProgramming #CodeImplementation #LiveCoding #JavaTutorial #CodeWalkthrough #JavaProject #PracticalCoding #HandsOnCoding #CodeDemo #WorkingCode #JavaDevelopment #CodeExample #RealWorldCoding LLD & System Design: #LowLevelDesign #LLD #SystemDesign #LLDImplementation #SystemDesignCode #LowLevelSystemDesign #DesignToCode #SoftwareDesign #CodeArchitecture #SoftwareArchitecture #SystemImplementation #DesignPatternImplementation #ObjectOrientedDesign #CleanArchitecture #ModularCode Interview & Career: #FlipkartInterview #MachineCodingRound #CodingInterview #TechInterview #InterviewPrep #CodingRound #InterviewCoding #LiveCodingInterview #PracticalInterview #TechInterviewPrep #SoftwareEngineerInterview #InterviewQuestions #FAANG #ProductCompanies #InterviewSuccess Design Patterns in Action: #DesignPatterns #StrategyPattern #FactoryPattern #ObserverPattern #DecoratorPattern #DesignPatternJava #PatternImplementation #PracticalPatterns #DesignPatternCode #PatternInAction #SoftwarePatterns #CodePatterns #ArchitecturalPatterns #ObjectOrientedPatterns #DesignPatternDemo Specific Project Features: #StackOverflow #StackOverflowClone #QASystem #ForumImplementation #UserManagement #AuthenticationSystem #FeedSystem #VotingSystem #FilteringSystem #TopicSubscription #QuestionAnswer #UpvoteSystem #InMemoryDatabase #DataManagement #CRUDOperations Educational & Learning: #JavaLearning #LearnJava #ProgrammingTutorial #CodingTutorial #JavaEducation #TechEducation #ProgrammingEducation #CodingEducation #SoftwareTutorial #TechTutorial #SkillDevelopment #ProfessionalDevelopment #DeveloperEducation #TechTraining #CodingSkills Code Quality & Best Practices: #CleanCode #CodeQuality #BestPractices #CodingBestPractices #JavaBestPractices #SoftwareBestPractices #CodeStandards #ProfessionalCode #IndustryStandards #CodeReview #SoftwareQuality #MaintainableCode #ExtensibleCode #ScalableCode #ReadableCode Technical Concepts: #JavaCollections #OOPConcepts #ExceptionHandling #Multithreading #ConcurrentProgramming #DataStructures #Algorithms #JavaOOP #Inheritance #Polymorphism #Abstraction #Encapsulation #JavaFeatures #CoreJava #AdvancedJava
