Object Oriented Programming Questions
Inheritance and composition are two fundamental concepts in Object-Oriented Programming (OOP) that allow for code reuse and building relationships between classes.
Inheritance is a mechanism where a class (called the child or derived class) inherits properties and behaviors from another class (called the parent or base class). The child class can access and use the attributes and methods of the parent class, extending or modifying them as needed. Inheritance promotes code reuse and supports the "is-a" relationship, where a child class is a specialized version of the parent class.
Composition, on the other hand, is a design technique where a class contains an instance of another class as one of its member variables. It represents a "has-a" relationship, where an object is composed of other objects. The composed object can be used to provide specific functionality to the containing class, and it can be easily replaced or modified at runtime. Composition promotes flexibility and code organization.
In summary, the main difference between inheritance and composition in OOP is that inheritance focuses on the relationship between classes, allowing for code reuse and specialization, while composition focuses on the relationship between objects, allowing for flexibility and modular design.
