A subclass is a derived class in object-oriented programming that inherits properties and behaviors from a parent class, allowing for code reuse and extension. It can override or extend functionalities of the parent class while maintaining a hierarchical relationship, enabling polymorphism and encapsulation.

Subclass

subclass

A derived class, also known as a subclass, is a class that inherits properties and behaviors from another class called the base or superclass, allowing for code reuse and extension of existing functionality. This mechanism is fundamental in object-oriented programming, enabling polymorphism and encapsulation through inheritance hierarchies.

derived class

Object-oriented programming (OOP) is a programming paradigm centered around the concept of objects, which are instances of classes, encapsulating data and behavior together. This approach promotes code reusability, scalability, and organization through principles such as inheritance, encapsulation, polymorphism, and abstraction.

object-oriented programming

A parent class, also known as a superclass, is a class that provides attributes and methods to its derived classes, enabling them to inherit common behavior and state. This concept is central to object-oriented programming, promoting code reuse and establishing a hierarchical relationship between classes.

parent class

Code reuse refers to the practice of using existing code for new functions or projects, reducing redundancy and improving efficiency in software development. It enhances maintainability and scalability by allowing developers to leverage proven, tested code components across various applications.

code reuse

Extension refers to the process of expanding, enlarging, or prolonging something beyond its original limits, often used in various academic and practical contexts such as linguistics, mathematics, and computer science. It involves the application of existing knowledge or systems to new areas, thereby increasing their scope and utility.

Polymorphism is a fundamental concept in object-oriented programming that allows objects of different classes to be treated as objects of a common superclass. This enables a single interface to represent different underlying forms (data types), enhancing flexibility and maintainability in code design.

polymorphism

Encapsulation is a fundamental principle in object-oriented programming that involves bundling the data and the methods that operate on the data into a single unit, or class, while restricting access to some of the object's components. This concept promotes modularity and enhances security by allowing controlled access and modification of the object's state through defined interfaces, typically using access specifiers like private, protected, and public.
