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.

How classes are defined?

In object-oriented programming , a class is a template definition of the method s and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables. … A class can have subclasses that can inherit all or some of the characteristics of the class.

How do you define a class with an example?

Definition: A class is a blueprint that defines the variables and the methods common to all objects of a certain kind. The class for our bicycle example would declare the instance variables necessary to contain the current gear, the current cadence, and so on, for each bicycle object.
