A class explains all the attributes of objects, as well as the methods that execute the behavior of member objects. It is a comprehensive data type, which shows a blue print of objects. It is a template of object.

A class can be explained as the primary building block of OOP. It also serves as a template that explains the properties, state, and behaviors common to a particular group of objects.

A class having data and behavior of an entity. For example, the aircraft class can have data, such as model number, category, and color and behavior, like duration of flight, speed, and number of passengers. A class inherits the data members and behaviors of other classes by extending from them.
