Hello Everyone👋👋 Can you override a private or static method? No. Private methods are not visible to subclasses, and static methods belong to the class, not the object, so they cannot be overridden. #Java #backend #frontend #FullStack #software #developer #programming #code #Java25 #lambda #API #super #constructor #Ollama #AI #GenAI #Anthropic #inheritance #MERN #Angular #Nodejs #React #AWS #tailwind #OOPS #class #object #interface #Array #interview

Hello Everyone👋👋 What is the difference between Collection and Collections? Collection: An interface at the root of the framework. Collections: A utility class with static methods for operating on collections (e.g., sorting, searching). #Java #backend #frontend #FullStack #software #developer #programming #code #lambda #API #aws #SpringAI #AI #GenAI #OpenAI #Java25 #Angular #Nodejs #React #MERN #JS #collection #Array #String #SpringBoot #tailwind #class #object #inheritance #Stack #interview

Hello Everyone👋👋 What is a functional interface? An interface with a single abstract method (e.g., Runnable). It can be implemented using a lambda expression. #Java #backend #frontend #FullStack #software #developer #programming #code #lambda #API #GenAI #OpenAI #SpringAI #super #constructor #SpringBoot #class #object #collections #Java25 #Angular #Nodejs #React #JS #functional #inheritance #interface #interview

🚀 Introducing My Java Complexity Analyzer ⚙️ I'm excited to share a personal project that I've been working on: a web-based tool that analyzes Java code to determine its time and space complexity. Key Features: 🧠 Time & Space Complexity Analysis: Provides insights into the efficiency of your code. 📊 Metrics Breakdown: Displays detailed metrics like loops, recursions, and array accesses. 🖼️ Visual Representation: Includes charts and graphs for better understanding. ⚡ Real-Time Feedback: Instant analysis with user-friendly interface. Tech Stack: Frontend: React.js Backend: Node.js Styling: Tailwind CSS This project was a great opportunity to deepen my understanding of algorithm analysis and improve my skills in full-stack development. 🔗 https://lnkd.in/gJKjrmzX #Java #ReactJS #WebDevelopment #Algorithms #BigO #Coding #SoftwareDevelopment #OpenSource

Hello Everyone👋👋 How does a HashMap work internally? It stores key-value pairs in “buckets” based on the hashCode() of the key. When a key is added, its hash code determines the bucket. If multiple keys have the same hash code (a collision), they are stored in a linked list or tree within that bucket. #Java #backend #frontend #FullStack #software #developer #programming #code #lambda #API #super #constructor #Java25 #OOPS #class #object #GenAI #OpenAI #SpringAI #SpringBoot #HashMap #Angular #Nodejs #React #JS #inheritance #Arrays #String #interview

Day 8 of making my self a BRAND 1 : Node js works with modules, there are core modules which are built in modules and external modules which can be installed from some package manager like npm, pnpm, yarn etc 2 : commonly used built in modules are fs, http, https, path etc 3 : commonly used external modules : express, dotenv, mongoose etc 4 : ask AI to list common modueles 5 : You might have heared about async in js but have you ever asked why it even exist, every body knows that async is which runs in the background but why to even run in the background. 6 : The reason that it exists because js in single threaded on browser and in node js environment as well so not to block the call stack in which the code is executed we use async in js #Nodejs #JavaScript #AsyncJS #WebDevelopment #BackendDevelopment #FullStackDevelopment #Coding #Programming #Developers #TechCommunity #NodeModules #CoreModules #ExpressJS #NPM #NodeTips #LearnNodeJS #NodeDeveloper #ServerSide #BackendEngineer #JavaScriptRuntime #100DaysOfCode #CodeNewbie #LearningInPublic #DeveloperJourney #SelfImprovement #BuildInPublic #CodingJourney #SkillUp #ContinuousLearning #TechEducation #AsyncProgramming #EventLoop #Concurrency #SingleThreaded #NonBlockingIO #WebServers #CodeBetter #DevTips #TechInsights #ProgrammingConcepts #Day8 #MakeYourselfABrand #PersonalBranding #DeveloperBrand #CodingMindset #ConfidenceInCoding #TechCareer #GrowthMindset #MotivationForDevelopers #LearnBuildGrow

🔍 Does JavaScript Really Have a Compiler? Let’s Clear the Myth! Many believe “Scripting languages don’t have a compiler.” But here’s the twist — JavaScript actually does! 🧠 Let’s decode this clearly 👇 1️⃣ Every JS engine has a compiler — Engines like V8 and SpiderMonkey compile your code behind the scenes. 2️⃣ It uses JIT (Just-In-Time) Compilation — Code is compiled while executing, not as a separate step like Java. 3️⃣ No .class or .exe files — JS compiles in memory and executes instantly. 4️⃣ Creation Phase = Internal Compilation — The engine sets up the execution environment, allocates memory, and imports modules before running the code. 5️⃣ Optimization on the fly — Frequently used (hot) code is recompiled and optimized for performance. So, the JavaScript is compiled, “It is, just not the way traditional languages do it!” ⚡ #JavaScript #WebDevelopment #ProgrammingConcepts #SoftwareEngineering #JSTips #TechCommunity #FrontendDevelopment #CodingInsights

Hello Everyone👋👋 What is the synchronized keyword? It’s used to create thread-safe code by ensuring that only one thread can execute a synchronized method or block at a time. #Java #backend #frontend #FullStack #software #developer #programming #code #lambda #API #GenAI #OpenAI #AI #SpringAI #Redis #Kafka #microservices #SystemDesign #class #object #Java25 #Array #Angular #Nodejs #React #JS #AWS #MERN #interface #interview
