• Stereotypes allow you to extend the vocabulary of the

UML so that you can create new model elements, derived from existing ones

• Examples:
• Stereotypes can also be used to classify method behavior such

as <<constructor>>, <<getter>> or <<setter>>

• To indicate the interface of a subsystem or system, one can

use the stereotype <<interface>> (Lecture System Design)

• Stereotypes can be represented with icons and

graphics:

• One can use icons to identify a stereotype
• When the stereotype is applied to a UML model element, the

icon is displayed beside or above the name ,#! ! #! Year ChangeDate Button ( WatchUser
