📘Easy summary
Object-Oriented Programming is a method of designing programs using objects and classes. Each object represents a real-world entity with specific properties and behaviors, and classes act as templates for creating multiple objects with similar characteristics. OOP emphasizes encapsulation, inheritance and polymorphism to manage data and behavior efficiently, which helps in modeling real-world problems. Benefits: modularity — code is divided into modules, easier to manage; reusability — classes and objects can be reused in many programs, reducing repetition; easier maintenance — changes in one part do not affect the entire system. OOP also supports scalability and adaptability and improves collaboration by making code understandable and organized.
⭐Key points
- Program built from classes and objects.
- Modularity, reusability, easier maintenance.
- Core: classes/objects, encapsulation, inheritance, polymorphism.
