Hey everyone! I'm a self-taught programmer and I've recently started learning Java. I feel pretty confident with most of the OOP concepts, but I'm still trying to wrap my head around encapsulation and abstraction. Right now, I'm struggling to figure out where and how to actually apply OOP in a project. I can create classes and understand object hierarchies, but when it comes to putting together a simple project, I get totally stuck. I even asked an AI for project ideas, and it suggested I work with class inheritance, but I'm not sure how to get started. Am I missing something important here?

There are tons of project ideas out there that can help you practice your OOP skills. Try picking something simple, like an Android app; that’ll naturally push you to use OOP principles. When you find something, break it down into smaller tasks and start wherever you feel comfortable. Got a specific project in mind that you're struggling with?
Be careful with OOP complexity! While it has great methodologies for building data structures, sometimes it can make things more complicated than necessary. If you're resource-driven, you might want to rethink when to mutate data.
You mentioned that you haven’t fully grasped encapsulation yet, and honestly, that’s really the crux of OOP. Understanding encapsulation will definitely help you move past that mental block. Try to think of a project where you can isolate certain behaviors and data within classes. For example, in a grid motion project, consider how to manage position and movement without tightly coupling everything.
Remember, a lot of OOP concepts are solutions to specific problems. It could be helpful to first experience a problem and then think about how OOP can solve it. For example, try making a simple game with a couple of weapons and an enemy. Doing it without OOP first and then refactoring could really help solidify your understanding.
Why not check out some existing projects on GitHub? Studying well-structured code can really clarify how to apply OOP concepts practically. It's like reverse engineering; you'll be able to see how everything fits together.
