How do you draw a state transition diagram in UML?

Steps to draw a state diagram –

  2. Identify the possible states in which the object can exist (boundary values corresponding to different attributes guide us in identifying different states).
  3. Label the events which trigger these transitions.

What is state transition in UML?
