What the system does and not how it is done.These additional capabilities include branching, parallel flow, swimlane, etc.An activity diagram is used to model the workflow depicting conditions, constraints, sequential and concurrent activities.It is a behavioral diagram that illustrates the flow of activities through a system.A uml activity diagram helps to visualize a certain use case at a more detailed level.

An example of uml activity diagram describing behavior of the purchase ticket use case for a ticket vending machine.They can also describe the steps in a use case diagram.The activity diagram represents the uml, which is used to model the workflow of a system.An activity diagram visually presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram.Before drawing an activity diagram, we must have a clear understanding about the elements used in activity diagram.

Here are the concepts explanation and an example.How to draw an activity diagram;On the other hand, the purpose of a use case is to just depict the functionality i.e.
