In object-oriented programming (OOP), a class is a blueprint or template for creating objects. It defines the properties (attributes) and behaviors (methods) that the objects created from the class will have. Classes enable modularity, reusability, and organized code structure, making complex systems easier to maintain and extend12.
Key Concepts of a Class
Attributes and Methods
Attributes: These are variables that hold data specific to the class. For example, in a Car class, attributes might include color, make, and model.
Methods: These are functions that define the behavior of the class. They can manipulate attributes and provide functionality. For example, methods in a Car class might include startEngine() and accelerate()2.

As an instance of a class, an object is constructed from a class via instantiation. Memory is allocated and initialized for the object state and a reference to the object is provided to consuming code. The object is usable until it is destroyed – its state memory is de-allocated.
Most languages allow for custom logic at lifecycle events via a constructor and a destructor.
