Class (programming)

In programming, a class is a syntactic entity structure used to create objects.: 1.3.3 The capabilities of a class differ between programming languages, but generally the shared aspects consist of state (variables) and behavior (methods) that are each either associated with a particular object or with all objects of that class.
