How are state transitions represented in a state machine?

State transitions in a state machine are depicted with a solid line that includes an arrowhead, indicating the direction of the transition from the source state to the target state. This representation clearly communicates the dynamic behavior of the system, illustrating how it moves from one state to another in response to events or conditions.

The solid line signifies an active relationship between the states, while the arrowhead signifies the flow of control or the triggering of an event that causes this change. This method of representation is essential for understanding how a system behaves over time, especially in complex systems where multiple states and transitions exist.

The presence of the arrowhead emphasizes the sequential nature of these transitions, making it easy to trace the life cycle of an object or system as it transitions through various states based on inputs received or conditions met. This clarity is crucial when analyzing system behaviors or designing software systems, ensuring that developers and stakeholders alike grasp the state dynamics effectively.
