You can populate your model with node elements  (classes, interfaces and enumerations),  and delete them from diagram, or from your project. When a node element is created in a UML Class diagram, the corresponding stub file is created in the current package.

In a similar way, IntelliJ IDEA helps create members  (fields, methods, or constructors)  in the node elements.

It is also possible to clarify the contents of diagrams with notes, which are created same way.

To create a node element in a uml class diagram
  1. Do one of the following:
    • Right-click the diagram background, or a package where a new node element should be created. Next, on the context menu, point to New, and choose element type from the submenu.
    • Press Alt+Insert, and choose element type from the pop-up frame.
  2. Specify the element name, or type the contents of a note, and click OK.
