Jan 3, 2025 · Class diagrams are a type of UML (Unified Modeling Language) diagram used in software engineering to visually represent the structure and relationships of classes within a system i.e. used to construct and visualize object-oriented systems.

Symbols representing relationships between classes in a Class Diagram. Class: A class represents an abstraction of a collection of objects (equally treated as the type of the same collection of objects). Class is the modeling and programming entity, that is instantiated later into a set of objects at run-time.

UML defines specific notations for each of the building blocks. A class is represented by a rectangle having three sections −. The visibility of the attributes and operations can be represented in the following ways −. Public − A public member is visible from anywhere in the system. In class diagram, it is prefixed by the symbol +.
