Java Matrix Multiplication with Arrays

🚀 Learning Java: Adding Arrays Today I practiced array addition in Java. Array addition means adding the corresponding elements of two arrays that have the same size and storing the result in a new array. This is usually done using a loop that goes through each index and performs the addition operation. It is a simple concept, but it helps in understanding array traversal, indexing, and basic data processing in Java. Practicing these small programs strengthens logical thinking and improves programming skills. 💻 #Java #Programming #CodingPractice #LearningJava #Arrays

⚙️ Learning Update : Multithreading Fundamentals in Java. Today I started exploring the Multithreading chapter in Java and learned several important concepts related to how operating systems and programs manage tasks and CPU execution. 🔹 Process vs Threads A process is an independent program in execution with its own memory space, while a thread is a smaller unit of execution within a process that shares the same resources. Threads help programs perform multiple tasks efficiently. 🔄 Context Switching Context switching occurs when the CPU switches from one thread or process to another, allowing multiple tasks to run seemingly at the same time. 🖥️ CPU Scheduling CPU scheduling is the method used by the operating system to decide which process or thread should use the CPU at a particular time. Efficient scheduling improves system performance and responsiveness. ⏱️ Time Sharing Time sharing allows multiple processes to share the CPU by allocating a small time slice to each process, giving the illusion that they are running simultaneously. 🔀 Multitasking vs Multithreading 🔹 Multitasking refers to running multiple programs at the same time. 🔹 Multithreading refers to running multiple threads within a single program simultaneously. 💡 Understanding these concepts is essential for building high-performance, responsive, and concurrent applications in Java. Excited to continue learning deeper concepts of multithreading and concurrent programming. #Java #Multithreading #Programming #SoftwareDevelopment #Coding #LearningJourney #ComputerScience #BackendDevelopment 🚀

☕ Java Interview Question 📌 What are the drawbacks of Garbage Collection? Garbage Collection simplifies memory management, but it comes with some trade-offs ⚖️ 🔹 Key Drawbacks: ✔ Performance Pauses – GC can cause application pauses, impacting performance ✔ Non-Deterministic Behavior – Hard to predict when GC will run ✔ Increased Memory Usage – Frequent object creation/destruction can add overhead 💡 In Short: While GC improves developer productivity, it may introduce latency and unpredictability in performance-critical applications 🚀 👉For Java Course Details  Visit : https://lnkd.in/gwBnvJPR . #Java #GarbageCollection #Programming #TechInterview #BackendDevelopment #Learning #AshokIT

🚀 Java Learning Journey | Day 15 | Core Java Learned about Wrapper Classes in Java. 💡 Key Concept: Wrapper classes convert primitive data types into objects. Example: int → Integer, double → Double ⚙ Why Important? • Required for Collections Framework (ArrayList, HashMap) • Enables autoboxing & unboxing • Useful in object-based operations 📚 Learning: Understanding how Java handles data as objects and why wrapper classes are essential in real-world applications. #JavaDeveloper #Java #CoreJava #OOP #Programming #CodingJourney #LearningInPublic #100DaysOfCode #DevelopersOfLinkedIn #BackendDevelopment

🚀 Day 17/45 – Learning Interfaces in Java On Day 17 of my Java learning journey, I explored the concept of Interfaces, which is an important part of Object-Oriented Programming. Interfaces help in achieving full abstraction and allow multiple inheritance in Java. 📚 What I Learned Today Today I learned: ✔ What interfaces are and how they work ✔ Difference between interface and abstract class ✔ How to implement interfaces using implements keyword ✔ Multiple inheritance using interfaces 💻 Practice Work To apply my learning, I implemented: • A basic interface example using shape • A multiple interface example demonstrating multiple inheritance 🎯 Key Takeaway Interfaces are powerful because they provide a way to achieve abstraction and flexibility in design. They help in building scalable and loosely coupled applications. Understanding these advanced concepts step by step is making my programming journey more exciting. #Java #Programming #LearningInPublic #CodingJourney #SoftwareDevelopment #OOP

🔍 **Mastering Sorting in Java: Comparable vs Comparator** In Java, sorting objects is a common task—but choosing the right approach makes all the difference! ✅ **Comparable** Used when a class has a *natural/default sorting order*. 👉 Implemented using `compareTo()` method 👉 Defined inside the same class ✅ **Comparator** Used for *custom or multiple sorting logic*. 👉 Implemented using `compare()` method 👉 Defined in a separate class or via lambda expressions 💡 **Key Insight:** Use *Comparable* for a single default sort, and *Comparator* when you need flexibility. 📌 Example: Sort Students by marks (Comparable) or by name/age (Comparator) 🔥 Understanding these concepts strengthens your problem-solving and coding skills in Java! #Java #CoreJava #Programming #Developers #Coding #JavaDeveloper #Learning #Tech

Today I Learned – Encapsulation in Java Understanding Encapsulation is a key step in mastering Object-Oriented Programming (OOP). --> What is Encapsulation? It is the process of binding data and methods together and restricting direct access to the data using access modifiers. Key Takeaways: --> Use private variables for data hiding --> Access data using getters & setters --> Improves security and control --> Enhances code maintainability & flexibility --> Makes applications more modular #Java #OOP #Encapsulation #Programming #SoftwareDevelopment #CodingJourney #LearnInPublic #Developers #Tech #JavaDeveloper

Java#P1 📌 Java Learning: How to remove duplicate characters from a string 👇 public class Remove Duplicates { public static void main(String[] args) { String str="programming"; String result=""; for (char ch : str.toCharArray()) { if (result.indexOf(ch) ==-1) { result+=ch; } } System.out.println("Original String: "+str); System.out.println("After removing duplicates: "+result); } } } 🧾 Output Original String: programming After removing duplicates: progamin 💡 indexOf() returns -1 → character not present Simple logic, but very useful in interviews. #Java #Coding #SDET #LearningInPublic

🚀 Day 7/45 – Working with Strings in Java On Day 7 of my Java learning journey, I explored the concept of Strings, which are used to store and manipulate text data in programs. Strings are widely used in almost every application, from user input to data processing. 📚 What I Learned Today Today I learned: ✔ What strings are and how they are created in Java ✔ Important string methods like length(), charAt(), and toUpperCase() ✔ How to compare strings using equals() ✔ Understanding case-sensitive and case-insensitive comparisons 💻 Practice Work To strengthen my understanding, I implemented: • A program to reverse a string • A program to count characters in a string • A palindrome checker using string logic 🎯 Key Takeaway Strings are a fundamental part of programming, and mastering string manipulation is essential for solving real-world problems. Consistent daily practice is helping me build strong fundamentals step by step. #Java #Programming #LearningInPublic #CodingJourney #SoftwareDevelopment #Consistency
