How can I effectively learn Object-Oriented Programming?
Asked by

I'm looking for some guidance on learning Object-Oriented Programming (OOP). I've seen a lot of suggestions regarding building games or analyzing open-source code, but that doesn't really help me since I'm just getting started. I know some basics like classes and the init method, but I'm struggling with important concepts such as inheritance, polymorphism, abstraction, and composition. I have a basic understanding of C++ and Python and I've implemented some data structures like lists, hash tables, linked lists, stacks, and queues. Any recommendations for resources or approaches to learn OOP?

If you prefer books, I recommend 'Big Java: Early Objects' by Cay Horstmann. It's a great resource for understanding OOP concepts and Java isn’t overly complex for beginners. You might find a digital copy online.

At its core, OOP revolves around objects that have properties and can perform actions. The four main pillars to understand are:
1. **Encapsulation**—hiding object properties and exposing them through methods.
2. **Inheritance**—subclasses inherit properties from superclasses.
3. **Abstraction**—hiding internal workings and exposing only what’s necessary.
4. **Polymorphism**—allowing objects to be treated as instances of their superclass.
It's a lot to take in, but since you’re already familiar with C++, you can practice these principles with it! Feel free to reach out for examples if you need them!

Consider starting with a Java or C# course. These languages naturally introduce OOP concepts as you dive in. I find that once you're engaged with the language, the principles become clearer!

You could check out platforms like Udemy or a subscription to Pluralsight. They usually have good courses focusing on OOP and C# that might be just what you need!

Reading 'The Object-Oriented Thought Process' can really help you shift your mindset towards OOP principles. After that, explore C++'s OOP features. Try building small projects to apply what you learn—consistency is key! Utilize resources like LearnCpp.com for a more structured approach.

DevEnthusiast14: I would advise against switching languages for now. You’ve started with C++, which is a solid choice for OOP, and sticking with it will definitely save you time as you deepen your understanding.
