Class Diagram - Class Notation
This section describes the Class Notation used in a UML Class Diagram. A Class Notation presents a class of objects which share the same set of properties and behaviors.
A Class Notation is the primary graphical notation used in a UML Class Diagram to represent a class of objects which share the same set of properties and behaviors. Conceptually, a class:
A Class Notation is drawn as a rectangle shape with 3 sections to list the class, its attributes and its operations.
For example, the "Time" class can be defined as:
Name: Time Attributes: public Integer hour public Integer minute public Integer second Operations: public void addHours(Integer) public void addMinutes(Integer) public void addSeconds(Integer)
This class can be drawn as a Class Notation in a UML class diagram as shown below:
Note that a Class Notation can be simplified to show the name section only.
