Questions and Answers

What does inheritance in object-oriented programming primarily involve?

  • Creating a new class based on an existing class to inherit its properties. (correct)
  • The process of hiding implementation details from the user.
  • Developing code that can take on multiple shapes or forms.
  • Extracting general concepts to simplify coding.

    • Which principle of OOP focuses on restricting access to certain components of an object?

  • Polymorphism
  • Encapsulation (correct)
  • Inheritance
  • Abstraction

    • 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)
  • Abstraction restricts user access to methods, while encapsulation does not.

    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.
