It’s here! 🎉 2026 State of Java Survey & Report    java is still a huge part of the enterprise IT landscape -- 50%+ off all applications -- and not going away anytime soon. But they are on the move: 81% of Java-based organizations are adopting open source Java (OpenJDK) at an increasing pace.

🔥 DAY 17 – Cleaner Java with Streams Java Streams make collection handling elegant. Example: List<String> names = users.stream() .map(User::getName) .collect(Collectors.toList()); Why use Streams? ✔ Less boilerplate ✔ Functional style ✔ Cleaner logic But don’t overuse it for complex logic. Readable > Fancy. #Java #CleanCode

You already know interfaces in Java. A Functional Interface is simply an interface with exactly one abstract method — nothing more. This constraint is intentional and it allows Java to represent behavior as a value. Runnable is a classic example. It defines a single contract: void run(); Because there is only one abstract method, the compiler can infer intent and accept a lambda as its implementation. Runnable task = () -> {   System.out.println("Executing task for Anwer Sayeed"); }; The lambda doesn’t replace Runnable. It implements its contract, concisely. This design choice is what enabled Java’s functional style without breaking its object-oriented foundations. #Java #FunctionalInterface #Runnable #LambdaExpressions #JavaDeveloper #CleanCode #Multithreading

Missed posting yesterday. Used the time to revise Java fundamentals. Revision in Java isn’t about rereading syntax. It’s about rediscovering why things work the way they do. Yesterday’s revision focused on: • How memory is managed inside the JVM • Why equals() matters beyond comparisons • How exceptions propagate through method calls • The real difference between == and .equals() These topics feel small — until they cause real bugs. Frameworks change. APIs evolve. But Java fundamentals stay relevant. Revising basics is not going backward. It’s upgrading how you think. Back today. Building on stronger foundations. #Java #CoreJava #JVM #BackendDevelopment #SoftwareEngineering #LearningInPublic #BuildInPublic
