It is required to develop an application in Java called Hospital Management System focusing on managing patient information and hospital services. The application will maintain information about patients registered in a hospital, their medical records, and the services provided. Write the following classes: A$.$ Class: Service This class will represent medical services offered by the hospital. Private Data Members: $$ serviceId $($String$,$ e$.$g$.,"$S$001")$ serviceName $($String$,$ e$.$g$.,$ "General Checkup"$)$ cost $($double$)$ duration $($int$,$ duration in minutes$)$ Public Methods: $$ Default constructor $$ Constructor with parameters $$ Set and get methods for all attributes $$ equals method to compare two services $$ toString method for displaying service details B$.$ Class: Patient This class will represent patients in the hospital. Private Data Members: $$ patientId $($long$)$ firstName $($String$)$ lastName $($String$)$ gender $($char$)$ email $($String$)$ medicalHistory $($ArrayList of type String, where each entry is a medical record$)$ servicesReceived $($ArrayList of type Service$)$ Public Methods: $$ Default constructor $$ Constructor with parameters $($excluding medicalHistory and servicesReceived$)$ Done by: Mrs$.$ Fatema Alshaikh $$ Set and get methods for all attributes $$ equals method to compare patients by patientId $$ printMedicalHistory method to display medical records $$ printServicesReceived method to display services received $$ toString method for displaying patient details. C$.$ Class: Hospital This class will manage the list of patients and services. Private Data Members: $$ patientsList $($LinkedList of type Patient$)$ servicesList $($LinkedList of type Service$)$ size $($int$,$ actual number of patients$)$ Public Methods: $1.$ Constructor without parameters, initializes patientsList and servicesList as empty lists and size to $0.2.$ addPatient: Adds a new Patient object to the patientsList. Returns true if added, false if patient already exists. $3.$ deletePatient: Deletes a Patient by patientId. Returns true if deleted, false if not found. $4.$ searchPatient: Searches for a Patient by patientId. Returns the index if found, or $-1$ if not. $5.$ isEmpty: Returns true if patientsList is empty, otherwise false. $6.$ listSize: Returns the size of the patientsList. $7.$ getPatient: Returns the Patient object at the specified index. $8.$ addService: Accepts a Service object and adds it to servicesList. $9.$ getService: Returns a Service object based on its ID$.10.$ printPatientDetails: Prints details of a Patient including their medical history and services received. $11.$ printPatientList: Print all patients in the patientsList. $12.$ printServiceList: Print all services in the servicesList. D$.$ Class: HospitalManagement This class will contain the main method to test functionalities. Main Method: $$ Display a menu$-$driven interface using a loop and switch statement to interact with the user. $$ Options include adding$/$removing patients, viewing patient details, searching for specific patient, adding medical services,and adding service to patient etc. NOTE: For linked list use Java$$s built$-$in LinkedList class. Write detailed comments for each class and method.
