A private hospital needs an application to manage COVID$-19$ vaccination records for its patients who are allergic to polyethylene glycol $($PEG$),$ polysorbate $80($PS$80)$ or gelatin. A member of the hospital staff enters the patient$$s basic information, such as their name, age and allergy, and decides which vaccine $($AstraZeneca or Pfizer$)$ is suitable, based on Table $2.$ The staff member then injects the selected vaccine and enters the information in the system. The system generates a report based on the patient$$s allergy, as shown in Table $1.$

III. Assessment Tasks

Design and build a console$-$based application that requires the user to enter patient details and recommended vaccine type via the command line and store them in an appropriate internal data structure.

$$ There is no requirement for this data to be preserved after the application is closed.

$$ You will need to consider what the application outputs to the user that demonstrates the results of each task below.

$$ You should provide the user with the means to close the program once user operations are complete.

Your application should be able to perform the following tasks as given in Section II$.($Scenario$)$:

Task A: Write pseudocode algorithms for the tasks given below.

$1.$ Store collected user input data $($i$.$e$.$ name, age, vaccine type and date$)$ based on initial check$-$up in an appropriate data structure. Sample data is provided in Table $1.$

Store sample data on the different allergies and recommended vaccine types in an appropriate data structure. Sample data is provided in Table $2.$

$2.$ Generate the sample report to show how many patients are given each vaccination type, as given in Table $3$ below.

Table $3$: Vaccine type given to patients

ID Vaccine Type Count

$1$ AstraZeneca $2$

$2$ Pfizer $4$

$3.$ Take user input then sort all patients by last name who were given the AstraZeneca$/$Pfizer vaccine. A sample output is shown in Table $4.$

Sample $-$ user input:

Enter the choice of vaccine type $($AstraZeneca$/$Pfizer$)$: AstraZeneca

$4.$ Give preference to patients based on age who are waiting for their next vaccination based on Table $1.$ A sample output is provided in Table $5.$

$5.$ Count the number of patients given for each allergy type based on Table $2.$ A sample output is provided in Table $6.$

Task B: Construct the application and implement algorithms.

$1.$ Develop a single Java program that follows coding conventions and enables the user to search, sort, count and provide list of patients waiting for their next vaccination appointments by using algorithms studied in this module, which are run from the command line. The application should be text$-$based and menu$-$driven.

$2.$ Implement all the algorithms you have created for Task A$.$

Note:

$$ You need to ensure that the user input is validated, and feedback is given when an invalid input is entered.

$$ Test all th
