📚 Main Topics

1. Encapsulation
2. Inheritance
3. Polymorphism
4. Abstraction

✨ Key Takeaways

• DefinitionEncapsulation is the bundling of data (attributes) and methods that operate on the data into a single unit, or class. It restricts direct access to some of the object's components.
• Implementation
  • Use private attributes to protect data.
  • Provide public getter methods to access and modify these private attributes.
  • Example: In an inventory system, an Item class can have private attributes like name and quantity, with public methods to get these values.

🧠 Lessons Learned

• Practice CodingThe best way to learn object-oriented programming is through hands-on coding. Experiment with creating classes, objects, and methods.
• Understand the PrinciplesFamiliarize yourself with the four main principles of OOP—encapsulation, inheritance, polymorphism, and abstraction—as they form the foundation of object-oriented design.
• Iterate and ImproveDon’t be afraid to break and fix your code. Iteration is key to mastering programming concepts.

🧠 Call to Action

• Start coding! Try to implement these concepts in your own projects. Modify existing code, create new classes, and explore the relationships between them. This practical experience will solidify your understanding of object-oriented programming in Java.
