(Largest Perimeter Triangle — Java 🔺) Hey everyone 👋 Today I explored how to find the largest perimeter triangle from a given array of side lengths using Java. While solving this, I understood how a simple mathematical condition can help in optimizing the entire logic 🔥 Here’s the breakdown 👇 🧠 Concept: To form a valid triangle from 3 sides, the sum of any two sides must be greater than the third one. → a + b > c → a + c > b → b + c > a 💡 Approach 1: Sort the array in descending order and check triplets from the start. If any 3 consecutive sides satisfy the triangle condition, their sum gives the largest perimeter. ⚡ Approach 2 (Optimized): Instead of reversing the array, just sort it in ascending order and iterate from the end — gives the same result but with cleaner logic and less work. 🧩 Time Complexity: O(N log N) 💾 Space Complexity: O(1) This problem helped me understand how sorting order and traversal direction can make an algorithm more elegant and efficient 🚀 📁 Code is available on my GitHub repo: https://lnkd.in/ekjD9s22 #Java #DSA #ProblemSolving #Arrays #CodingJourney #Developers #LearningByDoing #FullStackDeveloper #MCA #GitHub

/** Understanding the Thread Life Cycle in Java **/ If you’ve ever worked with multithreading, you’ve probably heard terms like Runnable, Waiting, or Terminated. But what really happens behind the scenes when a thread runs in Java? 🤔 Let’s break it down 👇 1️⃣ New When a thread is created (using Thread t = new Thread()), it’s in the New state. It exists, but it hasn’t started yet. 2️⃣ Runnable After calling t.start(), the thread moves to the Runnable state — it’s ready to run and waiting for the CPU to allocate time for it. 3️⃣ Running When the CPU picks it up, the thread goes into the Running state. This is where your code inside the run() method actually executes. 4️⃣ Waiting / Blocked / Timed Waiting A thread can be temporarily paused due to I/O operations, sleep(), wait(), or synchronization locks. It’s basically saying, “I’ll wait until the condition is right to continue.” 5️⃣ Terminated (Dead) Once the run() method finishes executing, the thread enters the Terminated state — its job is done! 💡 In short: A Java thread goes from being born → ready → active → waiting → dead. Understanding this life cycle helps you write cleaner, safer, and more efficient concurrent code. There is a vital keyword called synchronized to maintain consistency for multithreading.

🚀 Wrapping up my mini-series on Java Sealed Classes! Over the last two days, I explored what sealed classes are and how the permits keyword helps control inheritance. Today, let’s put everything together with one complete example — showing how sealed, final, and non-sealed subclasses can work in harmony. 💡 Here’s why I find sealed classes so valuable: - They bring clarity to your codebase — you instantly know all possible subclasses. - They add a layer of security and control, preventing unwanted inheritance. - They make your design cleaner and more maintainable in the long run. - And they work beautifully with pattern matching and switch expressions since the compiler knows every subclass. In short, sealed classes give Java developers the right balance between structure and flexibility — a small feature that makes a big impact on code quality. #Java #Java17 #SealedClasses #CleanCode #ProgrammingTips #OOP #CodeDesign #SoftwareDevelopment #JavaDeveloper

Did you know Java has its own mini garbage collector per thread? Not exactly, but it can feel that way. Each thread in Java has its own memory area (stack and local objects), while the JVM’s garbage collector manages cleanup concurrently across threads. That’s why one background thread may finish quickly, while another keeps the GC busy a little longer. Understanding how Java’s memory and GC threads interact can make you significantly better at debugging performance issues, especially when things behave unpredictably under load. Remember: “ Garbage collection isn’t magic , it’s just smart housekeeping. ” #Java #Programming #SoftwareEngineering #BackendDevelopment #Performance #JVM #MemoryManagement #LearnInPublic #DidYouKnowTech

🔄 Java Thread Communication: Coordinating Threads Safely In multi-threaded programs, multiple threads often share the same resources. Java’s wait(), notify(), and notifyAll() methods make sure those threads coordinate efficiently avoiding data conflicts and unnecessary CPU usage. Here’s what you’ll explore in this guide: ▪️Thread Communication Basics → How threads exchange signals while sharing objects. ▪️wait() → Pauses a thread and releases the lock until notified. ▪️notify() → Wakes one waiting thread on the shared object. ▪️notifyAll() → Wakes all waiting threads competing for the same lock. ▪️Producer-Consumer Example → A classic pattern showing how threads take turns producing and consuming data. ▪️Best Practices → Always call wait/notify inside synchronized blocks, check conditions in loops, and keep critical sections small. ▪️Advantages → Prevents busy waiting, improves performance, and ensures correct execution order. ▪️Interview Q&A → Covers the difference between notify() and notifyAll(), synchronization rules, and efficiency benefits. 📌 Like, Share & Follow CRIO.DO for more advanced Java concurrency lessons. 💻 Master Java Concurrency Hands-On At CRIO.DO, you’ll learn by building real-world multi-threaded systems from producer-consumer queues to scalable backend applications. 🔗 Visit our website - https://lnkd.in/gBbsDTxM & book your FREE trial today! #Java #Multithreading #Concurrency #CrioDo #SoftwareDevelopment #JavaThreads #Synchronization #LearnCoding

How Java Really Works: From Code to Execution Magic ⚙️ Ever wondered what happens under the hood when you hit Run on your Java program? Here’s the breakdown: 🔹 Compilation Phase: Your .java source files are compiled by javac into platform-independent bytecode (.class) — this bytecode isn’t tied to any specific OS or CPU. 🔹 Class Loading & Verification: When you execute your program, the ClassLoader dynamically loads the bytecode into the JVM, verifying its structure, access rights, and memory safety before execution. 🔹 Execution Phase: Inside the JVM, the Interpreter initially runs the bytecode line by line. But as execution continues, the Just-In-Time (JIT) Compiler identifies “hot” methods (frequently executed code paths) and compiles them into native machine code for blazing-fast performance. 🔹 Memory Management & Runtime Services: Meanwhile, the Garbage Collector (GC) reclaims unused memory, JIT optimizations inline hot paths, and runtime profiling continuously tunes performance. 💡 In essence — Java bridges portability and performance through the JVM’s layered architecture, blending interpretation, compilation, and runtime intelligence into one elegant engine. #Java #JVM #JIT #Programming #FullStackDeveloper #SpringBoot #SoftwareEngineering #Performance #BackendDevelopment
