Domain Classes and Objects. Objects that represent domain entities are called entities or domain objects. The classes they instantiate are called domain classes. Executing a use case involves creating, destroying, querying, and updating domain objects.
1 Class methods can access class variables and class methods directly. 2  Class methods cannot access instance variables or instance methods directlythey must use an object reference. 3  Also, class methods cannot use the this keyword as there is no instance for this to refer to.hey are associated with the class, rather than with any object. Every instance of the class shares a class variable, which is in one fixed location in memory. Any object can change the value of a class variable, but class variables can also be manipulated without creating an instance of the class.
