The UML Class diagram provides information about the classes we are going to declare, their relationships with each other, their attributes and their operations. The UML Class diagram depicts the detailed static design of our object oriented planned software. A Class is represented with a rectangular box divided into compartments used for holding its name, its attributes and its operations.<\/p>\n
An object is an instance of a class. Depicting an object in our diagram is done by drawing an empty rectangle and writing the object name + ‘:’ + its type and an underline. The underline will differentiate this depiction from a class description. A Class depiction doesn’t include the underline.<\/p>\n
The Class Name In\u00a0software engineering<\/a>, a\u00a0class diagram<\/b>\u00a0in the\u00a0Unified Modeling Language<\/a>\u00a0(UML) is a type of static structure diagram that describes the structure of a system by showing the system\u2019s\u00a0classes<\/a>, their attributes, operations (or methods), and the relationships among objects.<\/p>\n The class diagram is the main building block of\u00a0object-oriented<\/a>\u00a0modeling. It is used for general\u00a0conceptual modeling<\/a>\u00a0of the structure of the application, and for detailed modeling, translating the models into\u00a0programming code<\/a>. Class diagrams can also be used for\u00a0data modeling<\/a>. The classes in a class diagram represent both the main elements, interactions in the application, and the classes to be programmed.<\/p>\n In the diagram, classes are represented with boxes that contain three compartments:<\/p>\n In the design of a system, a number of classes are identified and grouped together in a class diagram that helps to determine the static relations between them. In detailed modeling, the classes of the conceptual design are often split into subclasses.<\/p>\n In order to further describe the behavior of systems, these class diagrams can be complemented by a\u00a0state diagram<\/a>\u00a0or\u00a0UML state machine<\/a>.<\/p>\n UML provides mechanisms to represent class members, such as attributes and methods, and additional information about them like constructors.<\/p>\n
\n<\/strong>UML suggests that a class name should start with a capital letter, be centered in the top compartment, be written in a boldface font and be written in italics if the class is abstract.<\/p>\n\n
