Before we learn Object Diagram, let's understand-
A class represents things that are put together having common behavior. It is a blueprint of an object-oriented system
Let us consider an exciting example of classes and objects. We all know cars like Ferrari, Volkswagen, Mercedes, and Porsche, etc. These are all cars manufacturing companies. Here, we can consider that a car is a class and Ferrari, Mercedes are the objects
In this tutorial, you will learn:
Objects are the real-world entities whose behavior is defined by the classes. Objects are used to represent the static view of an object-oriented system. We cannot define an object without its class. Object and class diagrams are somewhat similar.
The difference between the class and object diagram is that the class diagram mainly represents the bird's eye view of a system which is also referred to as an abstract view. An object diagram describes the instance of a class. It visualizes the particular functionality of a system.
The above UML object diagram contains two objects named Ferrari and BMW which belong to a class named as a Car. The objects are nothing but real-world entities that are the instances of a class.
Serial no. | Class | Object |
1 | It represents static aspects of a system. | It represents the behavior of a system in real time. |
2 | It doesn't include dynamic changes. | It captures runtime changes of a system. |
3 | It never includes attributes or data values of an instance. | It includes attributes and data values of any instance. |
4 | Class diagram manipulates the behavior of objects. | Objects are instances of classes. |
