[Java] Describe the relationship between an object and its defining class

When used in object-oriented programming, a class is a factory for creating objects. (We are talking here about the non-static part of the class.) An object is a collection of data and behaviors that represent some entity (real or abstract). A class defines the structure and behaviors of all entities of a given type. An object is one particular "instance" of that type of entity. For example, if Dog is a class, than Lassie would be an object of type Dog.
