• The UML includes class diagrams to illustrate
  classes, interfaces and their associations.
• They are used for static object modeling

How to show Methods in Class diagrams
A uml method is the implementation af an
operation. Here we are mixing static and dynamic
views in the same diagram, because the method
body (which defines dynamic behavior) adds a
dynamic element to the static class diagram

Generalization is in UML shown with a solid line
and a fat triangular arrow from the subclass to
the superclass (see figur 16.1) (it mens that
each instance of the specific classifier is also
an indirect instance of the general classifier.
Another name is inheritance. Dependency
indicates that a client element of any kind
(classes, packages, usecases and so on) has
knowlegde of another supplier element and that a
change in the supplier could affect the client-
Dependency is illustrated with a dashed arrow
line from the client to supplier see next
slide.
