Java: Balancing Performance and OOP Principles

📘 Today I revised OOP concepts in Java. Java is built on 4 main pillars: ✔ Encapsulation – Wrapping data and methods together ✔ Inheritance – One class acquiring properties of another ✔ Polymorphism – One method, multiple behaviors ✔ Abstraction – Hiding implementation details Understanding OOP makes code reusable and maintainable. Small improvements every day 💪 #Java #OOP #SoftwareDevelopment

Object-Oriented Programming (OOP) is fundamental to Java development. It shifts the focus from functions to designing software around real-world objects. Why does OOP matter? - Cleaner code structure - Better reusability - Easy maintenance and debugging - Faster development for large applications Core OOP Concepts in Java: - Encapsulation: Secure data using access control - Inheritance: Reuse existing code efficiently - Polymorphism: One interface, multiple behaviors - Abstraction: Show what matters, hide complexity The DRY Principle emphasizes writing common logic once and reusing it everywhere, leading to less repetition and better quality code. OOP enables the creation of scalable, maintainable, and industry-ready Java applications. Master OOP, and Java becomes much simpler.

Well explained 👏 OOP fundamentals are essential for building scalable and maintainable Java applications. Strong basics always make a difference.

Object-Oriented Programming is the backbone of Java. Here’s a quick overview of the four core OOP concepts every Java developer should know: 🔸 Encapsulation – Wrapping data and methods together and controlling access using access modifiers. 🔸 Inheritance – Reusing and extending existing classes to reduce code duplication. 🔸 Polymorphism – One interface, many implementations (method overloading & overriding). 🔸 Abstraction – Hiding implementation details and showing only essential features. These concepts help in building scalable, reusable, and maintainable Java applications 🚀 Currently strengthening my Java fundamentals and practicing real-world examples. #Java #OOPs #ObjectOrientedProgramming #JavaDeveloper #Programming #BackendDevelopment #LearningJourney

--- 🔍 Understanding how data is passed to methods is a core Java concept. ✅ Pass by Value Java passes a copy of primitive values. Changes inside the method do not affect the original variable. ✅ Objects in Java Java still uses pass by value, but the value is a reference. Modifying the object through this reference does affect the original object. 📌 Key takeaway: Java is always pass by value — the difference lies in what value is passed (primitive value vs object reference). 💡 Visual learning makes complex concepts easier.

🚀 Today’s Java OOP Learning – Object Class Methods Today I explored important methods of Java’s Object class: ✅ toString() ✅ equals() ✅ hashCode() ✅ getClass() ✅ clone() Implemented examples to understand how object comparison, hashing, and string representation work internally. This really helped me understand how Java handles objects behind the scenes. Practicing step by step and pushing code daily on GitHub to stay consistent. 🔗 GitHub Code: https://lnkd.in/gMxUuJji #Java #OOPS #LearningInPublic #DSA #JavaDeveloper #CodingJourney

🚀 Java Object-Oriented Programming (OOP) – Visual Guide Object-Oriented Programming is the backbone of Java. This visual explains how a Class works as a blueprint, defining attributes (like color and speed) and methods (start(), stop()). From a single class, multiple objects can be created, each with its own data and behavior. It also highlights the four core pillars of OOP: 🔹 Encapsulation 🔹 Inheritance 🔹 Polymorphism 🔹 Abstraction Understanding these concepts helps in writing clean, reusable, and scalable Java applications. Perfect for beginners starting their Java journey! 💻☕ #Java #OOP #ObjectOrientedProgramming #JavaDeveloper #LearningJava #ProgrammingBasics #TAPACADAMY

📘 Day 25 | Core Java Series Polymorphism is one of the core pillars of Object-Oriented Programming in Java. It allows the same method to behave differently in different situations. Remember this: Overloading → Compile time Overriding → Runtime Once polymorphism is clear, Java OOP concepts start to connect naturally. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #OOP #Polymorphism #LearningInPublic

Day 8 of 100 | Java basics, but for real this time While revising Java, I realized I didn’t “learn” some things earlier — I just memorized them and hoped for the best A few myths I’m finally clearing up: ❌ “If the code compiles, it’s correct” ✔ Compilation checks syntax, not logic or edge cases. ❌ “More OOP keywords = better code” ✔ Turns out, readable code matters more than fancy words. ❌ “Stack and Heap is the whole story” ✔ Java said, there’s more happening behind the scenes. This time, I’m slowing down and actually understanding the fundamentals instead of racing through them. Laughing at my old mistakes, learning from them, and moving forward #Day8 #100DaysOfCode #Java #LearningInPublic #ProgrammingHumor #Consistency #Javafullstack #GenAI

📘 Day 18 | Core Java Series Constructor Overloading allows a class to have multiple constructors with different parameters. This helps create objects in different ways while keeping the code clean. Remember this: Same constructor name Different parameter list ❌ Return type is not allowed in constructors. Understanding this makes object creation and OOP concepts much clearer. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #LearningInPublic #JavaBasics #OOP
