This example demonstrates how to to generate Javacode from a statechart. The procedure is explained in the documentation, chapter "Java code generator".
In summary, there are two traffic lights: one for the traffic on the street, and one for pedestrians who want to cross the street. They can push a button to request their traffic light to turn green, which activates a blinking wait-light first. The street's traffic light then goes through the standard procedure, turning on the yellow light, followed by the red light, allowing the pedestrians to cross safely. After some time, the pedestrians' traffic light turns red again, and the cars are allowed to pass until the next request is made by a pedestrian.
Additionally, the traffic light can be switched off completely. This turns the yellow lights into a blinking mode, signaling that the traffic light is indeed switched off and that the street should be crossed in a careful manner.
