Data Entry with Exceptions

We will simulate a data entry system where users are prompted to enter numeric data, which is saved. The system will handle invalid input, and allow the user to enter a secret ADMIN interface.

User Stories

  1. As a system user I am prompted to enter a whole number so that my data is stored in the system.

  2. The program will add each valid item to a List<Integer>.

  3. As a user, if I enter non-numeric or floating-point data I am shown an error message, and the program continues so that I can enter numeric data.

  4. Non-numeric data causes an exception, which the program must handle.

  5. All invalid entries are written to another List.

  6. As a user, if I type EXIT I am given confirmation that I am exiting the system, and the program ends. Otherwise I can continue entering numeric data into the system.

  7. As a user, if I enter the string ADMIN, I am prompted to enter a password so that I can continue.

  8. As a potential admin user, if I enter the secret password PASSWORD, I am presented with a menu so that I can choose from the following options: 

    Options:
1. View valid user input history
2. View invalid user input history
3. Exit Admin Menu

  9. As an admin user, I can enter the following options to cause the following actions:

  10. 1: I can view the list of valid input.
  11. 2: I can view the list of invalid input.
  12. 3: I can exit this menu.

  13. If I enter an invalid number or non-numeric character, I am prompted with the same menu.

  14. As an admin user, if I enter the wrong password, I am returned to the data entry screen.

  15. Create a custom checked exception named AdminAuthenticationException. If the user enters an invalid password, exit the admin interface methods by throwing this exception.

Stretch Goals

  1. As an admin user, I want a menu option to allow me to see the maximum and minimum numbers entered.

  2. As an admin user, I want a menu option to allow me to see the longest-length invalid data entered.

  3. As an admin user, I want to be able to remove a single item from the list of invalid strings.

  4. Should the user enter the String itself? The index of the String?
