Advanced Topics in Object-Oriented Programming (OOP) While the core principles of OOP (encapsulation, inheritance, polymorphism, and abstraction) provide a solid foundation, several advanced concepts enhance the power and flexibility of object-oriented programming. Design Patterns Design patterns are reusable solutions to commonly occurring problems in software design. They provide a proven blueprint for creating flexible and … Read more
Abstraction is a fundamental concept in object-oriented programming (OOP) that focuses on the essential features of an object while hiding unnecessary details. It simplifies complex systems by providing a higher-level view of the problem. Key Concepts: Types of Abstraction: Example: Consider a car. When driving, you focus on steering, accelerating, and braking. You don’t need … Read more
Encapsulation is a fundamental principle of object-oriented programming (OOP) that binds together data (attributes) and the methods that operate on that data into a single unit, a class. This binding creates a protective shield that prevents data from being accessed by the code outside this shield. Key Concepts: Example: Python In this example: Benefits of … Read more
Polymorphism is a core principle of object-oriented programming (OOP) that allows objects of different types to be treated as if they were of the same type. It enables flexibility and extensibility in code. Types of Polymorphism Python Python Example: Python Key Points By understanding polymorphism, you can write more flexible and adaptable object-oriented code. Read … Read more
Inheritance is a fundamental concept in object-oriented programming (OOP) that allows one class to inherit the properties and methods of another class. The class that inherits is called the subclass or derived class, and the class being inherited from is called the superclass or base class. Syntax: Python Example: Python Key points: Types of … Read more
