Problem must be solved using java multithreading
Budget: $2 – $8 USD
A Hospital department has a Doctor (D) who helps patients with their Health. The D’s office is rather
small and has room for only one desk with a chair and computer. There are three chairs in the hallway outside the office where patients can sit and wait if the D is currently helping another patient. When there are no patients who need help, D sits at the desk and takes a nap. If a patient arrives and finds the D sleeping, the patient must awaken the D to ask for help. If a patient arrives and finds the D currently helping another patient, the patient sits on one of the chairs in the hallway and waits. If no chairs are available, the patient will come back at a later time. Using threads, implement a solution that coordinates the activities of the D and the patients. Details for this assignment are provided below.
The patients and the D Using threads begin by creating n patients. Each will run as a separate
thread. The D will run as a separate thread as well. patient threads will seek help from the D. If the D is available, they will obtain help. Otherwise, they will either sit on a chair in the hallway or, if no chairs are available, will seek help at a later time (random period of time). If a patient arrives and notices that the D is sleeping, the patient must notify the D using a semaphore. When the D finishes helping a patient, the D must
check to see if there are patients waiting for help in the hallway. If so, the D must help each of these patients in turn. If no patients are present, the D may return to napping. Simulating the D providing help to a patient is to have the appropriate threads sleep for a random period of time
