What is the OOPs concept?<\/span><\/h2>\n

OOPs, concepts in programming<\/span><\/strong> are the core principles of Object-Oriented Programming (OOP). It revolves around organizing code based on objects, representing instances of classes.<\/span><\/p>\n

Let’s take the example of a “Car” class as a blueprint for creating car objects. It has attributes such as “color,” “model,” and “price,” along with behaviours like “start” and “stop.”<\/span><\/p>\n

By creating instances of the Car class, like “myCar,” you can assign specific values and start the associated behaviours. For example, you can set “myCar.color” to “red” and initiate the car by calling the “myCar.start()” method.<\/span><\/p>\n

OOPs concepts in programming<\/span><\/h2>\n

The following are the fundamental OOPs concepts in programming<\/strong>:<\/p>\n

1. Classes and Objects<\/span><\/h3>\n

Classes define the blueprint for creating objects, while objects are instances of classes. Classes have attributes (data) and behaviours (methods). For example, a “Person” class can have attributes like name, age, and behaviours like walking.<\/span><\/p>\n

2. Encapsulation<\/span><\/h3>\n

It is bundling data and methods within a class and controlling access to them. This ensures data integrity and code reusability. For instance, in a “BankAccount” class, the account balance may be private. So, the account is accessible only within the class.<\/span><\/p>\n

3. Inheritance<\/span><\/h3>\n

Inheritance allows the creation of new classes based on existing classes. This practice promotes code reuse and hierarchy. Moreover, the child class inherits attributes and methods from a parent class. For example, a “SavingsAccount” class can inherit from the “BankAccount” class.<\/span><\/p>\n

4. Polymorphism<\/span><\/h3>\n

This enables objects to be treated as instances of their own class or their superclass. It allows the same interface for objects of different classes, enabling flexibility and extensibility. For example, a “Shape” class may have a “calculateArea” method. So, both a “Rectangle” and “Circle” class can use this method for their respective formulas.<\/span><\/p>\n

5. Abstraction<\/span><\/h3>\n

Abstraction focuses on creating simplified models of complex systems. It hides the implementation details and discloses only essential information. This helps in modularity and managing complexity. For example, a “Car” class can have a “startEngine” method. This method might abstract the underlying complex processes required to start the engine.<\/span><\/p>\n
