Java LTS Release Highlights: Key Features in Java 8-22

Key Features in the Last 4 LTS Releases of Java This infographic covers major features across Java 8, 11, 17, 21, and 22: Java 8 — Lambda, Stream API, Date/Time API, Optional class Java 11 — HTTP Client, var in lambdas, String improvements Java 17 — Sealed classes, Records, Pattern Matching, Enhanced Switch Java 21 — Virtual Threads, Sequenced Collections, Pattern Matching for switch Java 22 — Unnamed Variables, Streams for Primitives, Statements before super() A quick reference for Java developers to track language evolution across LTS versions. #Java #JavaDeveloper #Java8 #Java11 #Java17 #Java21 #Java22 #LTS #Programming #SoftwareDevelopment #BackendDevelopment #SpringBoot #CodeNewbie #100DaysOfCode #TechEducation #LearnJava #JavaProgramming #OpenJDK #VirtualThreads #LambdaExpressions #LinkedInTech

Java 21 virtual threads = 100x better memory efficiency. 10,000 concurrent users: - Java 17: 2GB memory - Java 21: 200MB memory Should you upgrade? Depends. https://lnkd.in/eNti373x

🚀 My Java Learning Journey The core components of Java 🔹 JDK (Java Development Kit) – The complete toolkit for developing Java applications. It includes JRE and development tools like compiler (javac). 🔹 JRE (Java Runtime Environment) – Provides the environment to run Java programs. It includes JVM and essential libraries. 🔹 JVM (Java Virtual Machine) – The heart of Java! It converts bytecode into machine code and ensures platform independence. 💡 How Java Works: 1. Write code in ".java" file 2. Compile using JDK → converts into bytecode (".class") 3. JVM executes the bytecode → runs on any platform ✨ This is why Java is called "Write Once, Run Anywhere" #FortuneCloudTechnology #CravitaTechnologyPune #Java #Programming #LearningJourney #JDK #JVM #JRE #Coding #SoftwareDevelopment

🧠 Understanding Java Memory Model (JMM) Why does volatile matter? Java Memory Model defines: ✔ How threads interact through memory ✔ Visibility guarantees ✔ Ordering rules Without volatile: One thread may not see updates made by another thread. volatile ensures: ✔ Visibility ✔ No instruction reordering But: volatile ≠ thread safety for complex operations. Understanding JMM is crucial for writing safe concurrent code. #CoreJava #Multithreading #JavaMemoryModel

🚀 Day 46/50 – #50DaysOfCode Today, I learned about methods and recursion in Java. These concepts help in writing reusable code and solving problems more efficiently. ☕💻 #Day46 #JavaFullStack #Java #CCBP #NxtWave #LearningJourney #Consistency

Day 4 of revising Java fundamentals. Today I focused on understanding threads and how Java handles concurrent execution. Topics revised: • What is a Thread • Thread lifecycle • Creating threads (extends Thread / implements Runnable) • start() vs run() • Basic multithreading concepts Understanding threads helped me see how programs can run multiple tasks simultaneously and improve performance. Still learning step by step. #Java #Multithreading #CodingJourney #SoftwareDevelopment #LearningInPublic

🔹 What is an Interface in Java? An interface is a blueprint of a class that contains only abstract methods (method without body). It tells "what to do" but not "how to do". - Example: A remote control – it has buttons, but how the TV works internally is hidden. - Key Points: ✔ All methods are abstract by default (before Java 8) ✔ Supports multiple inheritance ✔ Used to achieve 100% abstraction + Why use interface? - Improves flexibility - Supports multiple inheritance - Helps in loose coupling #fortunecloudtechnology #Java #MultipleInheritance #Interface #OOP

☕ Today’s Java Learning: JDK vs JRE vs JVM (Now It Feels More Practical) Today I revised one of the most important Java fundamentals: JDK vs JRE vs JVM. Earlier, this used to feel like just an interview question. But while revisiting it today, it connected much better with real development work. My simple understanding now: 🔹 JVM → Executes Java bytecode 🔹 JRE → Provides runtime environment + libraries 🔹 JDK → JRE + development tools like javac, jar, debugger The best part of relearning fundamentals after experience: 👉 You stop memorizing definitions 👉 You start connecting them to real execution flow Now it makes more sense why: ✅ Spring Boot apps need the right JDK version ✅ Runtime issues often relate to JVM behavior ✅ Build and deployment pipelines depend on JDK tooling Sometimes the most basic topics become the most meaningful when revisited with production experience. 🚀 Back to Java fundamentals, one concept at a time. #Java #CoreJava #JDK #JRE #JVM #ContinuousLearning #FullStackDeveloper #SoftwareEngineering

Today I learned a simple difference in Java: ArrayList and Vector both store data in a dynamic way. But, ArrayList → faster, not thread-safe Vector → slower, thread-safe That’s it. Small concept, but important to understand when to use what. #java #learning #dsa
