Jan 3, 2025 · A usage dependency relationship in a UML class diagram indicates that one class (the client) utilizes or depends on another class (the supplier) to perform certain tasks or access certain functionality.

We can open diagrams either by right-clicking the project in the Project tool window and selecting Diagrams | Show Diagrams, or by using the shortcut ⌥⇧⌘U (macOS) / Ctrl+Alt+Shift+U (Windows/Linux). You'll notice this gives you several diagram options to choose from.

Jul 25, 2013 · One class depends on another if the independent class is a parameter variable or local variable of a method of the dependent class. If your class a had an instance variable, you would use the association link instead.

I've used GraphViz/dot to generate many useful types of diagrams, from visualizations of Spring contexts to IntelliJ module dependencies, to visualizations of complex XML documents. Look around and see what you find.

Nov 25, 2009 · I've used it, and found it quite useful. It will draw diagrams based on relations that it inferred automatically, or that were specified by special javadoc tags. Yes, but this one uses java source files (javadoc) rather then class files (isn't that what the OP is looking for?)

Mar 3, 2025 · In the Project tool window, right-click a package for which you want to create a diagram and select Diagrams | Show Diagram Ctrl+Alt+Shift+U). In the list that opens, select Java Class Diagram . IntelliJ IDEA generates a UML diagram for classes and their dependencies.

In UML, a dependency relationship is a relationship in which one element, the client, uses or depends on another element, the supplier. You can use dependency relationships in class diagrams, component diagrams, deployment diagrams, and use-case diagrams to indicate that a change to the supplier might require a change to the client.

Dependencies: UML class diagrams depict dependencies between classes through dashed lines with an arrow pointing from the dependent class to the independent class. Dependencies indicate that a change in one class may affect another class, but there is no direct association or relationship between them.

Dependencies represent a relationship between classes where one class depends on another class. In a UML class diagram, dependencies are shown as dashed lines with an arrow pointing from the dependent class to the independent class. Dependencies can be based on method parameter types, return types, or other factors.

UML Class Diagrams are an essential tool for visualizing and designing object-oriented systems. They help developers understand the structure of the system, identify dependencies between classes, and communicate the system’s design to stakeholders.
