The fastest way to fail a Java interview? Not by writing bad code. By forgetting which Java version shipped the feature you’re confidently using every day. Because you forgot which Java version introduced what. And that one blank moment? It kills confidence. Breaks momentum. Sometimes costs the offer. You know Java. But when the interviewer asks: “What came in Java 17?” “Java 11 vs 21?” “Which version introduced Virtual Threads?” Your mind freezes. So I built the resource I wish I had before every Java interview: Java 8 → Java 26 19 versions Interview-critical features Release dates Code snippets LTS versions highlighted All in one swipeable carousel. No Googling. No tab switching. No panic. Just swipe once and walk in prepared. ☕ 💾 Save this before your next interview 🔁 Repost this for the next Java dev 📤 Share it with someone preparing right now 👇 Comment the Java version you use in production Follow 👉 Sayed Muddassir Hussain 👈 for practical Java + backend content that actually helps you get better. If this reaches the right developer at the right time, it might genuinely change their next interview. Make sure it does. #Java #JavaDeveloper #BackendEngineering #SoftwareEngineering #SystemDesign #JavaInterview #SpringBoot #Quarkus #CodingInterview #Java21 #Java25 #TechCareers #Programming #100DaysOfCode

I built the Java interview resource I wish I had. Interview prep can be overwhelming. Topics are scattered, and it's hard to know where to focus. This guide brings everything together in one place. Java SE 8 through SE 24. → Modern Java : Pattern Matching, Records, Virtual Threads, Stream Gatherers → Core Fundamentals : Strings, Wrapper Classes, Text Blocks, var → OOP & Design Patterns : Singleton, Factory, Strategy, DI → JVM Internals : JIT, Garbage Collection, Memory Management → Collections Framework : including Java 21's SequencedCollection Every concept is explained with code examples and comparison tables. Share it with someone who could benefit from it. #Java #JavaDeveloper #InterviewPrep #SoftwareEngineering #TechCareers

Top 5 Java 8 features every developer should know 1. Lambda Expressions 2. Streams API 3. Functional Interfaces 4. Optional Class 5. Method References If you’re preparing for interviews, you will definitely be asked these. Don’t just learn syntax— understand where to use them. #Java #Java8 #Coding #BackendDeveloper #InterviewPrep

🔥 Day 11: Comparable vs Comparator (Java) One of the most important concepts for sorting in Java — especially for interviews 👇 🔹 1. Comparable 👉 Definition: Defines the natural (default) sorting of objects inside the class itself. ✔ Found in java.lang ✔ Uses compareTo() method ✔ Only one sorting logic per class 🔹 2. Comparator 👉 Definition: Defines custom sorting logic outside the class. ✔ Found in java.util ✔ Uses compare() method ✔ Supports multiple sorting logics 🔹 When to Use? ✔ Comparable → when class has natural/default order ✔ Comparator → when you need multiple or dynamic sorting 💡 Real-Life Analogy: Comparable = Default rule 📏 Comparator = Custom rule 🎯 📌 Final Thought: "Comparable gives you one way to sort, Comparator gives you many." #Java #Comparable #Comparator #Programming #JavaDeveloper #Coding #InterviewPrep #Day11

🚀 Java Cheat Sheet – Simple Concepts That Stick If you're working with Java daily (or preparing for interviews), having a clear understanding matters more than trying to memorise everything.
