Behavioral diagrams, on the other hand, show the dynamic behavior between the objects in the system, including things like their methods, collaborations, and activities. When an object sends a message to another object, it implies that the two classes have a relationship that must be shown on a class diagram. A class diagram is a collection of classes similar to the one above.
