Day 63 of #100DaysOfCode – Multithreading in Java 🧵 Today, I explored Multithreading in Java — a powerful concept that allows multiple tasks to run at the same time, improving performance and responsiveness. 🔹 What is Multithreading? Multithreading means executing multiple threads simultaneously within a program. A thread is just a lightweight process that runs independently. 🔹 Why Multithreading? Faster execution Better CPU utilization Useful in games, web servers, chat apps, real-time processing 🔹 Ways to Create Threads in Java 1️⃣ Extending Thread class 2️⃣ Implementing Runnable interface 💡 Takeaway Multithreading makes programs efficient, but must be handled carefully to avoid race conditions and inconsistency. 10000 Coders Gurugubelli Vijaya Kumar #Java #Multithreading #FullStackDeveloper #Learning #CodeJourney #100DaysOfCode

🚀 Stream API Coding – 1: Check if a String is Palindrome Exploring the power of Java 8 Stream API with a simple yet elegant example — checking whether a string is a palindrome using functional style. 💡 String s = "racecar"; boolean isPalindrome = IntStream.range(0, s.length() / 2) .allMatch(i -> s.charAt(i) == s.charAt(s.length() - i - 1)); System.out.println(isPalindrome ? "String is Palindrome" : "String is not palindrome"); ✨ Key Learnings: ✅ Use IntStream.range() for index-based iteration ✅ allMatch() ensures all comparisons pass ✅ Clean and concise approach — no loops, no extra variables 📚 Output: 👉 String is Palindrome This is just the beginning — more Stream API challenges coming soon! 🔥 #Java #StreamAPI #CodingChallenge #JavaDeveloper #FunctionalProgramming #CleanCode #CodingSeries #InterviewPreparation

Kotlin Inlines && Extensions Well, inlining is all about higher-order functions where we pass lambdas besides generics. So the question is: does the code execute at the caller site or the called site? The obvious answer is the called site. So to overcome that, we let the compiler copy-paste the lambda block at the caller site. Problem solved. Now comes another problem — especially when threading is involved. If the inlined block runs in a different coroutine scope or thread, then a return inside it might try to return from the outer function, which is not valid. So, since we are asking the compiler to copy-paste the block, we use the keyword crossinline to prevent non-local returns and respect return boundaries. Otherwise, if we don’t want the lambda to be inlined at all, we use noinline. Extension functions are about extending functionality to a class we frequently use. But at the bytecode level, they are just static Java functions where the receiver object becomes the first parameter, and the return type remains the same. Meaning, they are syntactic sugar — no real class extension or modification happens. #Kotlin #AndroidDevelopment #MobileDevelopment #AndroidEngineer #SoftwareEngineering #CleanCode #ProgrammingConcepts #TechLearning #CodeBetter #DevelopersLife

🚀 Accessing Static Members Using the Class Name in Java (Oop Concepts) In Java, static members are associated with the class itself, not with instances of the class. Consequently, you should always access static members using the class name, rather than an instance of the class or the `this` keyword. Using the class name clarifies that you are accessing a shared, class-level property or method. This promotes code clarity and avoids confusion about the scope of the variable or method.

🚀 Diving Deep into Java Multithreading! Today I spent time revising and practicing one of the most powerful yet tricky parts of Java — Multithreading & Concurrency. 💡 Here’s a quick snapshot of what I covered: 🔹 Thread Fundamentals - Extending Thread vs Implementing Runnable - Key methods: start(), run(), join(), sleep(), yield(), interrupt(), setDaemon(), setPriority() 🔹 Synchronization & Locks - synchronized blocks/methods and their drawbacks — no fairness, indefinite blocking, lack of interruptibility - ReentrantLock, tryLock(), lockInterruptibly(), unlock() - ReentrantReadWriteLock with read/write segregation - Fair vs Unfair locking 🔹 Thread Communication - wait() - notify() - notifyAll() 🔹 Executor Framework & Thread Pools - Executor - ExecutorService - ScheduledExecutorService - Pool types: newFixedThreadPool, newCachedThreadPool, newSingleThreadExecutor - Future and Callable — async task handling - Methods like submit(), invokeAll(), invokeAny(), shutdown(), awaitTermination() - Advantages of thread pools efficient resource use, faster response, controlled concurrency 🔹 Concurrency Utilities - CountDownLatch - CyclicBarrier for coordination - CompletableFuture with supplyAsync(), thenApply(), allOf(), orTimeout(), exceptionally() 🔹 Core Concepts - Thread safety - volatile - atomicity Every topic added another layer of depth to how I think about parallelism, synchronization, and performance in real-world backend systems 💪 #Java #Multithreading #Concurrency #ExecutorFramework #CompletableFuture #BackendDevelopment #LearningJourney #Coding

Day 15: Covariant Return Type in Java In Java inheritance, we can't change the return type when overriding a method, but there's an exception called covariant return type. This means we can change the return type to a subtype of the original one (only for non-static methods). What's happening here? The parent class A defines a car() method that returns a P object. The subclass B overrides car() and changes the return type to Q, which is a subclass of P. This is allowed because Q is a covariant return type of P. Why does this matter? This allows you to return a more specific type in the subclass without breaking the contract of the parent method. It gives you more flexibility in your code. 10000 Coders #Java #Inheritance #LearningJourney #JavaDeveloper #Day15 #SoftwareDevelopment #LearningEveryday
