What are the fundamental principles of Object-oriented programming?

I am looking to understand the basic concepts of Object-oriented programming. Can someone provide a brief explanation on the key principles?

Object-oriented programming is based on four basic principles: encapsulation, abstraction, inheritance, and polymorphism. Each of these principles helps developers to create well-structured, efficient and reusable code. In simple words, encapsulation refers to the bundling of data and methods within an object, abstraction hides the unnecessary details and only shows essential features, inheritance allows for the creation of new objects based on existing ones, and polymorphism allows objects to take on multiple forms.

The key principles of Object-oriented programming are encapsulation, inheritance, and polymorphism. These principles promote code reusability, maintainability and scalability. Encapsulation allows for the hiding of object data and methods from the rest of the code, inheritance facilitates code reuse by allowing new objects to access the attributes and behaviours of existing ones, and polymorphism allows for the flexibility of objects to take on different forms and behaviours.
