I'm retaking my Java Object-Oriented Programming (OOP) course for the third time at university, after failing it twice already. I initially started as a Computer Science major but switched programs, yet I need this class to graduate. I've always struggled with OOP; the assignments felt overwhelming, and my professor mostly just reads from lecture slides. Plus, we have to write our code by hand on exams, which stresses me out when I'm under time pressure. I need to average at least 50% in tests and the final exam; otherwise, it's game over for me in this program. If anyone has helpful resources or study tips—especially for grasping concepts like inheritance, polymorphism, and encapsulation, or even just strategies for handling a paper-based Java exam—please share! I'd really appreciate any advice!

OOP can be abstract, which might make it confusing. I'd recommend looking into some books or resources that explain encapsulation and other concepts differently. Consistent practice and possibly getting help from tutors or classmates who understand the subject might also be beneficial. You could find a lot of helpful material online, such as from learnjava or similar sites.
You might want to tackle those assignments you didn't like. Sometimes it’s because there was a specific concept that wasn’t clicking for you. Understanding the reasons behind OOP can really help. Remember, OOP isn’t exclusive to Java; it’s found in other areas too, and knowing that reasoning is crucial.
Yeah, I didn’t get a lot of concepts either. I switched majors, but I still need this for graduation, and the exams here are tough.
A cool approach I tried was making my own versions of common data structures like a mini search engine using my own ‘List’ interface. Working on projects like that can really solidify your grasp of OOP concepts. Plus, creating something unique lets you see how to apply the theories in real coding scenarios!
For the written exams, I practiced coding in Notepad to simulate the test environment. You can set up VSCode to disable features like intellisense and autocomplete, which will make you more comfortable writing code without help. It might seem odd, but it really sharpens your syntax skills! Also, if your textbook isn't doing it for you, consider checking out alternative ones; they often provide unique insights that can make a big difference.
Years back, I took a really helpful MOOC course that simplified OOP concepts. Sometimes hearing the same ideas explained in a fresh way can make everything click. Give it a shot and see if it helps!
Try building a super simple Java app that uses OOP principles without relying on tutorials too much. Use an IDE like VSCode, but avoid getting help from AI tools like CoPilot. For example, create a 'Pet' class and make 'Cat' and 'Dog' subclasses. Each pet should have properties like name, breed, and age, and a 'makeSound' method that prints the sound they make (like 'woof' for dogs, 'meow' for cats). This will help you grasp inheritance and polymorphism in a hands-on way!
