A Java Swing parking to monitor the state of parking spots in a parking lot creating a continuous car-threads traffic simulation and illustrating a case of concurrency solved by means of two Semaphores.
- The application creates a parking system as a shared resource for cars to park, providing 107 regular parking spots and 2 reduced-mobility spots reserved for disabled drivers.
- Two different Semaphore objects regulate the acquiring and releasing of permits to park in the regular/reduced-mobility parking spots.
- The application generates an infinite time-paced flow of threads, each representing a car requesting a permit to use the parking lot.
- The Car objects generated include attributes of a random license plate number in Spain's format, a random brand and car model picked from a resource file and the attribute of being a reduced-mobility car or not regulated by a probability factor.
- Requests to Semaphores take a timeout 'patience' argument and a boolean fair argument set to true.
- A TimeGenerator provides distinct random times to be used by several timed events in the application, such as the CarGenerator pace, cars requests patience timeout and cars stay in the parking spot.
- A Graphical User Interface depicts the state of every parking spot at any given time and provides information of the parked vehicles.
