12+ Difference Between Object And Class Diagram. An object reserves its state or information in attributes of a class and exposes their behaviour at the time of its instantiation along with invoked. Class diagrams and object diagrams use almost identical notations.
An object diagram shows this relation between the instantiated classes and the defined class, and the relation between these objects in the system. Object diagrams play a smaller role in uml. Class and object are two most important concepts of an object oriented programming language.
It is a uml diagram that illustrates how objects (instance of a class) interact with each other.
12+ Difference Between Object And Class Diagram. They are be useful to explain smaller portions of your system, when your system class diagram is very complex, and also sometimes modeling recursive. Attributes are the properties while the methods are the operations. class diagrams can contain objects. Class diagram represent generalized view of system while object diagram represent view of a system at a particular instant.
