Programming I Tutorial Week 14 - OOP 22nd Semester1436- 1437

Write a program for a system to manage the patients in hospital. The program should allow the following; to add patient to an array, retrieve information of a patient, arrange patients based on priority.

Create a class Patient that has the following private instance attributes: name, ID , priority( 1 , 2 , 3 ) and a static attribute which is numberOfPatients.

Patient provides a constructor that initializes the name, ID, priority and increments numberOfPatient by one.

Write the following public methods that perform each of the following tasks:printPatientInfo() : Method prints the information(Name ,ID and priority) of a patient.

Write an application class called Hospital with a main method that displays the menu: 1. Add new patient.2. Retrieve patient’s information.3. Arrange Patients based on priority.4. Exit.

Your code should include the following Methods: addPatient : that adds information of new patient ( name, ID, priority) to the end of the

array. The method should check if the patient is already registered or not. This method will return true if the add operation was completed successfully.

searchPatient : search for a specific patient. The search key of the search is ID. Method should return false for not found patient.

ArrangePatients: arrange patients in a new array according to their priority, patients with priority of 1 are emergency cases and should be added to the beginning of the array, patients with priority of 2 are moderate cases and should follow. Finally patients with a priority of 3 are routine cases and should be placed at the end of the array.Your method should then print sorted array.

All input data should be provided by user.
