In UML modeling, you can illustrate that a class supports,
or relies on, the behavior that is defined in an interface.
A diagram must be open in the Modeling perspective
and it must contain at least one class and one interface.
To specify that a class implements an interface:
- In the Palette, in the Class Diagram
Drawer, click Implements.
- In the diagram editor, click the class and drag the cursor
to the interface.
- Optional: Type a name for the implementation
relationship.
