Hello World! Application Requirements

The requirements of this application are very basic. They are as follows:

• Enable the user to enter a name to say Hello! to and output the string Hello< name>!.

• Don’t let the user submit the entry form without entering a name. If he does, provide an error message to help him fill the form out correctly.

• To add more Controller functionality (and have a bit more fun), the application should not allow the user to say hello to people they’re “not allowed” to talk to.

• To demonstrate Model components, the application should use a Model component to save the name entered for later.

This basic application provides a little bit of functionality in all three of the Model, View, and Controller components.
