A programmer can model real-world entities as objects for better program design and organization. A class defines a type of object with attributes and methods. Many instances of a class type can be created to represent multiple objects in a program.

Classes promote reusability. Classes add benefits like data abstraction and encapsulation, which organize code for better usability and extensibility.
