Create a Contacts app modeled after the Cover Viewer app. Store the contact information in an ObservableList of Contact objects. A Contact should contain first name, last name, email and phone number properties (you can provide others). When the user selects a contact from the contacts list, its information should display in a Grid of Text-Fields. As the information is modified (a Contact’s data is updated, a new Contact is added or an existing Contact is deleted), the contacts ListView should display the updates. The ListView should display the Contact’s last names.
