Start and End States

A start state explicitly shows the beginning of a workflow on an activity diagram or the beginning of the events that cause a transition on a statechart. You can have only one start state on a statechart or activity diagram.

An end state represents a final or terminal state on an activity diagram or statechart diagram. Place an end state when you want to explicitly show the end of a workflow on an activity diagram or the end of a statechart diagram.
