Java Method Overloading Benefits

Today, I explored one of the most important concepts of Object-Oriented Programming — Inheritance. Inheritance allows one class to acquire the properties and behavior of another class, making code more reusable and structured. I practiced three types of inheritance in Java: 1. Single Inheritance One class inherits from another. #oopsconcept #inheritance #java #codingjourney

Write Java like a senior developer with these 10 tips. Most of these features exist since Java 9–21 but developers still don't use them. Records, var, switch expressions — are you using these? Drop a comment if you knew all 10 👇 #java #programming #softwareengineering #coding #javadeveloper

Today I learned about Abstraction in Java. Abstraction is a core concept of Object-Oriented Programming that focuses on hiding implementation details and showing only essential functionality. To understand it better, I implemented a simple payment system using an abstract class. Through this example, I understood: - How abstract classes work - How implementation is hidden from the user - How different behaviors can be achieved using the same structure I’m continuing to strengthen my understanding of Java and OOP concepts. #Java #Abstraction #OOP #LearningJourney

💻 Understanding Multithreading in Java 🧵⚡ Most beginners watch multithreading… but don’t actually understand how it works internally. So today, I broke it down visually 👇 👉 In Java, multithreading allows multiple tasks to run concurrently within the same process. 👉 All threads share the same memory space, making execution faster and more efficient. 🔍 What’s happening behind the scenes? The main thread starts execution The JVM manages threads & memory Multiple threads run tasks in parallel Once completed → control returns to the main thread ⚡ Why it matters? ✔ Better CPU utilization ✔ Faster execution ✔ Improved application responsiveness 💡 Real-world use cases: Background tasks (file processing, logging) Web servers handling multiple requests Games & real-time systems 🚀 Key takeaway: Don’t just learn syntax — understand how things work under the hood. That’s what separates a coder from a developer. #Java #Multithreading #Concurrency #BackendDevelopment #100DaysOfCode #Learning #SoftwareEngineering

Day 6 - Externalization Vs Serialization in Java !! As we know, the Serializable interface in Java allows us to perform serialization, effectively turning an object into a byte stream for storage or transmission. What is externalization ? 💫 Externalization is a customized serialization mechanism. Unlike the Serializable marker interface, it allows developers to explicitly define the logic for saving and restoring an object's data through marshalling and unmarshalling. #java #backend #coding #developer #learning #springboot

🚗 Understanding Composition in Java (Strong Relationship) Today I learned an important OOP concept — Composition. 📌 In this example: A Car class contains an Engine object The engine is created inside the car → showing a strong relationship 👉 This means: If the Car does not exist, Engine also cannot exist independently 💡 Key Concept: Composition represents a "has-a" relationship where one object is dependent on another. 🔹 Flow: Car object is created Engine object is automatically created inside Car Calling startCar() → Engine starts first Then Car starts 🖥️ Output: Engine started Car started 🔥 This concept is very important for writing clean and modular code in Java. #Java #OOP #Composition #SDET #AutomationTesting #CodingJourney
