Study Notes

Object-Oriented Programming (OOP)

Key Concepts

  • Classes:
    • Templates for creating objects
    • Define properties and behaviors of objects
  • Objects:
    • Instances of classes
    • Have their own set of attributes (data) and methods (functions)
  • Inheritance:
    • Process by which one class can inherit properties and behavior from another class
    • Allows for code reuse and facilitates creation of a hierarchy of classes
  • Polymorphism:
    • Ability of an object to take on multiple forms
    • Enables objects of different classes to respond to the same method call
  • Encapsulation:
    • Concept of bundling data and methods that operate on that data within a single unit (class)
    • Hides internal implementation details from the outside world
  • Abstraction:
    • Showing only essential features while hiding non-essential details
    • Enables focus on key aspects of an object or system

OOP Principles

  • Single Responsibility Principle (SRP):
    • A class should have only one reason to change
    • Each class should have a single, well-defined responsibility
  • Open-Closed Principle:
    • A class should be open for extension but closed for modification
    • Enables adding new functionality without modifying existing code
  • Liskov Substitution Principle:
    • Subtypes should be substitutable for their base types
    • Ensures that derived classes can be used wherever their base classes can be used
  • Interface Segregation Principle (ISP):
    • A client should not be forced to depend on interfaces it does not use
    • Breaks large interfaces into smaller, more focused ones
  • Dependency Inversion Principle (DIP):
    • High-level modules should not depend on low-level modules, but both should depend on abstractions
    • Decouples high-level modules from low-level modules

Benefits of OOP

  • Modularity: Breaks down large programs into smaller, independent modules
  • Reusability: Enables code reuse through inheritance and polymorphism
  • Easier maintenance: Allows for modification of individual modules without affecting the entire program
  • Improved readability: Organizes code in a logical and structured way
