Explaining OOP with Memes: Encapsulation, Polymorphism, Inheritance, Abstraction

If you’re new to coding, Object-Oriented Programming (OOP) can feel like a maze of buzzwords. But at its core, it’s just about organizing your code into "blueprints." Think of a Class as a blueprint for a car. The Objects are the actual cars driven on the road (a Tesla, a Ford, a BMW). 😊😊

Every developer comes across the 4 Pillars of Object-Oriented Programming (OOP) early in their journey… but understanding them deeply is what truly makes a difference. This simple visual reminds us how powerful and practical these concepts really are 👇 🔹Abstraction Hiding complex implementation details and showing only the necessary features. It helps developers focus on what an object does rather than how it does it. 🔹 Encapsulation Bundling data and methods together while restricting direct access. It helps in protecting data and maintaining control over how it’s modified. 🔹 Inheritance It is a way of reusing predefined class, already defined class with is a relationship. This promotes code reusability and reduces redundancy. 🔹 Polymorphism Same message Given to the generalized thing for same behaviour but implemented differently. 💡 What I love is how even a simple meme can make these concepts easier to remember than long lectures! As developers, mastering these pillars helps us write clean, maintainable, and scalable code.

Interesting benchmark made the rounds recently — someone ran Claude Code across 13 programming languages to implement a simplified Git system. 600 total runs. Hard numbers. The results? Ruby, Python, and JavaScript came out on top — fastest, cheapest, and most stable. Statically typed languages like Go, Rust, and Java were 1.4–2.6x slower and more expensive to run. The takeaway isn't that static typing is bad — it likely pays off at scale — but for prototyping, dynamic languages give AI agents a real efficiency edge. Less boilerplate = fewer tokens = faster results. As engineers leaning into AI-assisted workflows, the language you choose with your agent matters just as much as the one you choose for your project.

📘 Day 24 – Diving Deeper into Java OOP Today, I dove into Polymorphism, a core OOP principle, and explored the super keyword, an essential concept in Java 💡 ❶ Polymorphism lets methods behave differently based on context, making code more flexible, maintainable, and adaptable for future changes. ❷ super gives a child class direct access to parent constructors, methods, and variables, enabling clear constructor chaining and method reuse. 📚 Hands-On Practice: → Method Overloading (Compile-Time Polymorphism) → Method Overriding & Dynamic Method Dispatch (Run-Time Polymorphism) → Calling parent constructors/methods via super() and super.method() 💡 Why It Matters: → Polymorphism makes code adaptable to future changes → super ensures parent–child relationships are used properly Step by step, turning OOP fundamentals into real coding power! #Java #OOP #Polymorphism #SuperKeyword #CodingJourney #LearningInPublic #SoftwareEngineering

Rust is not an OOP language. There is no inheritance; but you can achieve polymorphism through traits and generics. Learning how to write generics and traits has upped my game as a developer and allowed me to write much more robust and dynamic code as a result. When I was first writing out genpass-rs, I was just using it to learn Rust; but after some time with the language and practicing new concepts I would learn from both my classes and the official Rust book-- I was able to step-up my game and utilize language features to reduce redundant code and implement DRY principles in my project. There are still some modules that I need to work on, but these new concepts allowed me to completely rewrite password generation and made the code much more maintainable and readable.

What is different between a functionand a methood in programming? It is a classic question that trips up almost everyone starting out. The distinction is actually quite simple once you look at where the code lives and how it is called. In short: All methods are functions, but not all functions are methods. What is a Function? A function is a self-contained block of code that performs a specific task. You can think of it as a standalone "recipe." It is defined outside of any class and can be called directly by its name. Global Scope: It exists independently. Data: It only knows about the data you explicitly pass into it (arguments). Common in: C, Python (standalone), JavaScript (standalone). What is a Method? A method is a function that is associated with an object (or a class). It represents a behavior or action that an object can perform. Scoped to a Class: It is defined inside a class. Implicit Data: It has access to all the data (properties) stored inside the object it belongs to. Calling Syntax: It is usually called using "dot notation" (e.g., object.method()). Common in: Java, C#, Python (inside classes). #GameDev #IndieDev #GameDevelopment #SoftwareEngineering #Programming #ExpectationVsReality #CodingLife #TechHumor #DeveloperLife #Debugging #GameDesign #ProjectManagement #ScopeCreep #StartupLife #Creativity #CareerReality #WorkLifeBalance #BehindTheScenes #GameIndustry

This year Easter project for me was (finally) starting to learn Rust. Great book I found https://lnkd.in/dE_uEMZf <quote> Every few years, a programming language emerges that genuinely changes how practitioners think about their craft. Rust is one of those languages. Not because it introduces revolutionary concepts (most of its ideas have decades of academic heritage), but because it makes previously theoretical guarantees practical and enforceable at compile time. For developers steeped in object-oriented programming, Rust presents both a challenge and an opportunity: the challenge of unlearning habits that no longer serve, and the opportunity to write code that is simultaneously safer, faster, and more expressive than what came before. </quote> After reading about third of it (and going through half of the Rustlings puzzles) I fully agree with Enzo Lombardi. Rust is something different, something new. Demanding and fascinating. Opinionated, stubnorn and crazy powerful. I see a lot of discussions with Opus on the topics like borrow checker and lifetimes in my future weeks.

LeetCode Challenge – Day 13 Today I solved Problem 13: Roman to Integer (Easy). Roman numerals use seven symbols Roman numerals are usually written from largest to smallest. But when a smaller numeral appears before a larger one, we subtract it instead of adding it. Approach: Store Roman numeral values in a HashMap. Traverse the string from left to right. If the current value is less than the next value → subtract it. Otherwise → add it to the result. Time Complexity: O(n) Space Complexity: O(1) Practicing problems daily helps strengthen problem-solving and coding skills. #LeetCode #Day13 #Java #CodingChallenge #ProblemSolving #Programming #100DaysOfCode

I recently shared a short blog where I explain Object-Oriented Programming (OOP) in JavaScript along with its four core concepts — Encapsulation, Inheritance, Polymorphism, and Abstraction — using simple and beginner-friendly examples 💡 If you're learning JavaScript or just brushing up your OOP fundamentals, this might be useful for you 🚀 👉 Read the blog here: https://lnkd.in/g-B4g5gk Hitesh Choudhary | Piyush Garg | Suraj Kumar Jha | Chai Code | Akash Kadlag ☕ #JavaScript #OOP #WebDevelopment #Programming #LearnInPublic #Blog #Cohort2026

Most beginners skip OOP. That's a mistake. The 4 pillars of Object-Oriented Programming are the foundation of every scalable backend: 📦 Encapsulation — keep your data protected inside a class 🧬 Inheritance — don't repeat code, extend it 🎭 Polymorphism — one interface, many behaviours 🎨 Abstraction — show only what matters, hide the rest I applied all 4 when building my Student Grade Management System — and it made the codebase so much easier to maintain and scale. OOP isn't just theory. It's how real projects are built.
