Change

The Change option allows users to change the first name, last name, phone number, and email address of the selected contact. The JSP page responsible for generating this page (the change.jsp file) uses the <util:include> tag to include the GUI from the edit.jsp file. Existing properties appear with their current values, which users can change or accept.

Control flow passes from the change.jsp file, which collects the information, to the doChange.jsp file, which submits the changes and returns users to the address book home.
