How is abstraction different from encapsulation in OOP principles?
How is abstraction different from encapsulation in OOP principles?
- Abstraction simplifies code while encapsulation does not.
- There is no difference; they are the same principle.
- Encapsulation hides details, while abstraction focuses on the concept of what is being implemented. (correct)

Study Notes
Object-Oriented Programming Principles
- Four fundamental principles: inheritance, encapsulation, abstraction, and polymorphism.
Inheritance
- A core OOP concept.
- A "base class" (or super-class) defines general properties.
- One or more "sub-classes" inherit these properties.
- Sub-classes can add their own unique properties.
Encapsulation
- Hides the internal implementation details of a class.
- Users only need to know the interface (public methods).
- Internal code changes don't affect users if the interface doesn't change.
Abstraction
- Creates generalized code.
- Focuses on the concept rather than the specific implementation.
- Separates implementation details from the overall concept
Polymorphism
- Greek for "many forms".
- Refers to the ability of an object to take on multiple forms or behaviors.
