Object-oriented or object-orientation is a software engineering concept, in which concepts are represented as "objects"
| Object |
| An object is a software bundle of related state and behavior. Objects are often used to model the real-world objects that you find in everyday life. |
| Class |
 A class is a blueprint or prototype from which objects are created. |
| Abstraction: |
| Data abstraction refers to, providing only essential information to the outside world and hiding their background details, i.e., to represent the needed information in program without presenting the details. |
| Encapsulation |
 Encapsulation means that a group of related properties, methods, and other members are treated as a single unit or object. |
| Inheritance |
| Inheritance describes the ability to create new classes based on an existing class. |
| Polymorphism |
| Polymorphism means that you can have multiple classes that can be used interchangeably, even though each class implements the same properties or methods in different ways. |
