create class diagram from sequence diagram

I have a sequence diagram, and I would like to create a class diagram from it.

This is the sequence diagram:

I'm struggling with classes operations (which class should I give what operations)

Solution

  • You can derive the class from the life line. Each is an instance of a class. With the used notation you can say that the title corresponds to the class name directly. The actor is some informal compromise and is not a class.

    The messages towards a life line correspond to operations of the class. E.g. ViewBookForm has onClick().

    In any case you can pinpoint only those operations you have in the diagram. And you can't find out the atributes. So your classes will be skeletons only.
