Detailed explanation-1: -ACTIVITY DIAGRAM is basically a flowchart to represent the flow from one activity to another activity. The activity can be described as an operation of the system. The basic purpose of activity diagrams is to capture the dynamic behavior of the system.. It is also called object-oriented flowchart.

Detailed explanation-2: -It envisions the dynamic behavior of the system as well as constructs a runnable system that incorporates forward and reverse engineering. It does not include the message part, which means message flow is not represented in an activity diagram. It is the same as that of a flowchart but not exactly a flowchart itself.

Detailed explanation-3: -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. Activity diagrams are often used in business process modeling. They can also describe the steps in a use case diagram. Activities modeled can be sequential and concurrent.

Detailed explanation-4: -What is the difference between activity diagrams vs flowcharts? Activity diagrams represent the flow of activities within a system and depict the workflow/ interaction between these various system activities. Flowcharts, on the other hand, represent the sequence of steps in an event, process, or system.
