Task B:

The Java program should be a console$-$based application that uses the command line for user input and output. It should include methods for each of the tasks described in the pseudocode above, and should use appropriate data structures $($such as ArrayLists and HashMaps$)$ to store and manipulate data.

The program should implement all of the algorithms described in the pseudocode. This includes methods for adding patients and allergies, generating reports, sorting and prioritizing patients, and identifying specific groups of patients.

Note:

The program should include input validation to ensure that the user enters valid data. If the user enters invalid data, the program should provide feedback and prompt the user to enter the data again.

The program should be thoroughly tested to ensure that it works correctly with a variety of inputs.
