OOPs Concept Courses

Object-oriented programming (OOPs) is a programming language model that is structured on objects rather than actions and data rather than logic. It is a programming paradigm based on the concept of objects, which contain data and methods, and is used to create reusable and maintainable software. OOPs is a way of thinking about programming in which the focus is on objects rather than functions and logic.
 

The central concept of OOPs is to divide a complex problem into smaller sets of problems by creating objects. This division of complex problems into objects makes it easier to understand, maintain and debug the code. OOPs also supports the concept of data hiding, inheritance, and polymorphism.
 

Features of Object-Oriented Programming 

Object-oriented programming features allow objects and their interactions to design applications and computer programs, including abstraction, encapsulation, inheritance, polymorphism, and composition. These features enable developers to create modular, reusable code. 
 

Data hiding is a principle that restricts direct access to some of the object's components. This property is also known as encapsulation, which helps protect the data from external interference.
 

Inheritance is the concept of reusing the properties and methods of an existing class into a new class. It is used to create a hierarchy of classes and help in reducing the amount of redundant code.
 

Polymorphism is the function of an object to take on different forms. In OOPs, an object can perform different behaviors depending on the context or the input given.
 

Association is a relationship between two or more classes where one class has an instance variable that references the other class. It enables classes to communicate with each other to work together to achieve the desired outcome. Association can be one-way (one class using the other) or two-way (both classes using each other). This relationship helps keep code organized and allows for code reusability.
 

Composition is a method of code reuse in which objects are composed of other objects. It allows for the definition of complex objects from simpler ones and creates a flexible relationship between objects. It also allows for easy maintenance, as changes to one object can be propagated to other objects in the composition.
 

Aggregation is a type of relationship between two classes in which one class can use the methods and properties of another class without being its parent. This type of relationship is known as a 'has-a' relationship, as it allows one class to access the attributes and methods of another class. Aggregation is also known as a 'weak' relationship as it does not require any parent-child relationship, and the classes can be used independently.
 

Dynamic binding refers to linking a method call to the correct method implementation at runtime. This enables the same method call to be mapped to different implementations depending on the type of object being used. This is in contrast to static binding, which maps a method call to the exact implementation regardless of the type of object being used. Dynamic binding enables polymorphism, which is the function of an object to take on different forms depending on the conditions to which it is applied. This allows for more flexibility and code reusability, as a single method can be used for different types of objects.
