Simulates different situations which happens inside an emergency room and manages the the patients and the hospital's staff.
--- General logic: The program starts by reading the information about the hospital and storing that information in an InputReader object. Then a management of the hospital is needed, so a HospitalManager object is created based on the input. Then the simulation starts. For every round the patients which come at the hospital in the current round are moved into the triage queue where they are sorted and then the nurses calculates their urgencies, but a nurse can calculate only one urgency. All the patients with the urgency calculated are then moved into the examination queue and then starts their examination. A list of doctors who can treat the patient's illness is created for every patient. Then, for every patient, the first doctor in the list takes action over patient. If the patient hasn't been at investigation, the doctor can send him to investigation or send him home with treatment. If the patient has been already at investigation, the doctor can send him home, can hospitalize or operate him. That doctor is then moved at the end of every other list he is found in and a connection between him and the patient he treated is made (the patient is added to the doctor's hospitalized patients list and the doctor is set as the doctor who is responsible for the patient). Then the patients the doctors sent to investigations are added in the investigation queue and then they are investigated and sent back in the examination queue. All the three queues sort the patients before working with patients placed within them. After this stage, the observers are notified, the round number is increased and the next round is simulated.
--- enums package The package contains the enums needed for interpreting values of different fields.
--- hospital package This package contains all the information and the majority of used methods, like the ones performed by doctors, nurses, ER technicians or even patients. The hospital's queues are also here.
--- hospital.patients package Here we have everything we need to manage the patients in the hospital.
--- hospital.patients.comparators package Here we have two classes based on the singleton pattern. They implement the Comparator interface and allow to compare urgencies and patients.
--- hospital.queues package Here are the three hospital's queues where the patients can be placed. They are implemented using a list and a sort option which sorts the patients using the PatientComparator instance.
--- hospital.staff package Here are the doctors, nurses and ER Technicians. The classes contains the methods specific for every kind of staff member.
--- hospital.staff.doctors package Here we found all the doctors. There is a basic class Doctor and particular classes for every kind of doctor.
--- services package This package contains the classes responsible for reading the input, printing the output and simulate the events. The InputReader class stores the data from the input file. The HospitalManager class is the core of the program. Here are simulated the rounds by moving the patients from a queue to another one or by hospitalizing them or sending home. The program's logic is in this class. It also uses the Observable pattern, being the notifier for the observers.
--- services.outputWriter package In this package can be found the classes responsible with the program's output. Every class is an observer, so they use the Observable pattern, being the observers.
