🚀 What is Java? Understanding Platform Independence Java is not just a programming language — it is a Language + Platform + Technology. 🔹 In traditional languages like C: Code → Compile → Machine-specific (.exe) → Runs only on that platform (e.g., Windows) 🔹 In Java: Code → Compile → Bytecode (.class) → Runs on JVM → Works on any platform (Windows, Mac, Linux) 💡 This is why Java follows the principle: “Write Once, Run Anywhere” (WORA) 👉 Key Takeaways: ✔ Java code is compiled into bytecode, not machine code ✔ JVM (Java Virtual Machine) makes Java platform-independent ✔ Same program can run on multiple operating systems without changes 📌 Java powers everything from desktop apps to web systems and enterprise solutions. #Java #Programming #Coding #Developers #Technology #JVM #SoftwareDevelopment

Hands-on learning! Created an IP Finder Tool to master Java networking. What it does: - Local IP lookup - Public IP lookup - Website to IP conversion Concepts applied: - Java Swing for UI - InetAddress for DNS resolution - External API integration (ipify.org) - Multi-threading for smooth performance Building practical projects > Just reading documentation Next up: Adding ping test and IP history GitHub: https://lnkd.in/dU--5Pnu #Java #Networking #Programming

Day - 1 Features of Java A Journey with Frontlines EduTech (FLM) and Fayaz S Java is one of the most popular programming languages Features of Java:- Simple:- • Easy to Learn and Use • Syntax is similar to C, C ++ • Removes complex features Object - Oriented:- • Based on OOP concepts Class, Object, Inheritance, Polymorphism, Encapsulatio • Master code reusable and secure Platform Independence:- • Java followed WORA WORA( Write Once , Run Anywhere) • Java code Runs on JVM (java virtual machine) • Works in windows, Linux, Mac Secure:- • No Direct memory access • Byte code verification • Built-in security features. Multi-threading:- • Can Run multiple tasks at the same time • Useful for gaming and web applications Robust:- • Strong memory management • Automatic garbage collections • Exception handling High-performance:- • Uses Just-in-time(JIT) compiler • Faster than memory other interpreted languages Distributed:- • Support networking • Can create a distributed application. #java #backendjava #Corejava #featuresofJava

Java 17 brought major improvements for modern application development, and it’s a great step forward for building scalable enterprise systems. 🚀 Some standout features I really like: ✅ Sealed Classes – Better control over inheritance and cleaner domain models ✅ Pattern Matching for switch (preview) – Cleaner and more readable logic ✅ Records – Less boilerplate for data carrier classes ✅ Enhanced Random Generator API – Better flexibility for random values ✅ Strong encapsulation of JDK internals – More secure and maintainable apps ✅ Long-Term Support (LTS) – Stability for enterprise production systems Why it matters: 🔹 Better performance 🔹 Cleaner code 🔹 Improved security 🔹 Modern language enhancements 🔹 Ideal for upgrading legacy systems Recently, many organizations are upgrading older Java versions to Java 17 to gain long-term support and modern capabilities.

Three dev tooling updates worth knowing about today. 🛠️ IntelliJ IDEA 2026.1: Cursor integration and platform upgrades Cursor now plugs into IntelliJ through the ACP Registry. This release also adds Java 26 support, makes Wayland the default on Linux, and expands built-in JavaScript and TypeScript features. Source: https://lnkd.in/eJQqDdFG 🛠️ Windsurf Wave 13: Parallel multi-agent sessions and Git worktrees Wave 13 adds first-class parallel agent sessions, side-by-side Cascade panes, Git worktree support, and a terminal profile aimed at steadier agent runs. SWE-1.5 Free is also the default model for the next three months. Source: https://lnkd.in/eiyhshyY 🛠️ DeepSeek-V4 preview: 1M-token context for long-running agents Hugging Face highlights DeepSeek-V4-Pro and DeepSeek-V4-Flash with 1M-token context, lower per-token compute, and smaller KV cache footprints. That makes long-context coding and tool-use agents more practical to run. Source: https://lnkd.in/eRsap-TK Full intel feed with daily updates: solomonneas.dev/intel

Java 26 dropped two weeks ago and honestly the Applet API removal hit me with some nostalgia. That thing has been deprecated since JDK 17 in 2021 but seeing it officially gone feels like an era closing. The stuff that matters though: HTTP/3 support baked into the HTTP Client API, value classes from Project Valhalla finally landing, G1 GC getting faster by cutting sync overhead between app threads and GC threads, and ahead-of-time caching now works with any garbage collector including ZGC. If you're running Java in production this is a real startup and throughput upgrade, not just syntax sugar. Anyone already testing 26 in their stack? #Java #JDK26 #Programming #OpenJDK #TechUpdates

This bug cost me hours and it wasn’t even visible. Pushed code that worked perfectly on my machine. CI pipeline failed instantly on Linux. The culprit? Something most developers never notice. We were migrating a Java Spring Boot application to Azure, with a Bitbucket CI/CD pipeline running on Linux. All tests passed locally on Windows. But the pipeline kept failing with this cryptic error: [ERROR] SomeTest.java:[1,1] illegal character: '\ufeff' [ERROR] class, interface, enum, or record expected No logic issue. No syntax error. The problem was UTF-8 with BOM, Windows had added 3 invisible bytes at the start of Java files. The Linux Java compiler doesn’t accept it. Fix: Re-saved files as UTF-8 without BOM -> pipeline turned green. 7 files affected. Hours saved (after hours lost 😄). Cross-platform differences (encoding, line endings, case sensitivity) can silently break CI pipelines. If you code on Windows but build on Linux, check your file encoding. Invisible characters can break very visible things. #Java #CICD #DevOps #SpringBoot #CloudMigration #TIL

Junrar (Java), Path Traversal (Zip-Slip), CVE-2026-28208 (Moderate) How CVE-2026-28208 Works The vulnerability exists in the `LocalFolderExtractor` component of Junrar, a Java RAR extraction library. It stems from a logical inconsistency between how path validation and file creation handle the backslash (\) character on Linux/Unix systems, allowing a Zip-Slip style attack. 1. Path Validation Bypass: The `createFile()` method in `LocalFolderExtractor.java` attempts to prevent path traversal by checking that the canonical path of a new file starts with the canonical path of the extraction directory (...
