In object-oriented programming, what is a class?

A class serves as a blueprint for creating objects in object-oriented programming. This fundamental concept allows developers to define properties (attributes) and behaviors (methods) that the objects created from the class will have. For instance, if you have a class called "Car," it might include attributes such as color and model, as well as methods like drive and stop.

When an object is instantiated from the class, it takes on those defined characteristics and behaviors, making it possible to create multiple objects with the same structure but different values. This promotes reusability and organization of code, as a class encapsulates everything related to the particular type of object.

In contrast, a specific instance of an object refers to a single realization of a class and does not function as a template. A database of functions describes a collection of functionalities but does not encompass the defining aspects of classes related to properties and behaviors. Lastly, a type of error in code is not relevant to the concept of a class, as it pertains to debugging rather than the structure of code.
