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
Test your understanding of OOP concepts, principles, and benefits. Covers classes, objects, inheritance, polymorphism, encapsulation, abstraction, and SOLID principles.
