What is a class definition Java?

A class is a group of objects that share common properties and behavior . For example, we can consider a car as a class that has characteristics like steering wheels, seats, brakes, etc. And its behavior is mobility.

A class — in the context of Java — is a template used to create objects and to define object data types and methods . Classes are categories, and objects are items within each category. All class objects should have the basic class properties.

A class is a template or blueprint from which objects are created . So, an object is the instance(result) of a class. Object Definitions: An object is a real-world entity. An object is a runtime entity.
