State Interface (ITrafficLightState):?

• The ITrafficLightState interface defines a method (Change) that allows the

state to transition to another state. The method accepts a TrafficLight object as

a parameter to facilitate the state change.

public interface ITrafficLightState

void Change(TrafficLight light);

• Each concrete state class (Red, Green, Yellow) will implement this interface, defining

the specific behavior of the traffic light for that state.
