Build a Java GUI program to manage a email mailing list, using the MVC design pattern.The application will allow a user to add add or remove an email address from the mailing list. The program will handle an empty input, will not allow duplicates, and doesnt allow removing an email thats not on the list. The program doesnt otherwise check whether a user input represents a valid email address.

I need to complete the ADDs comment sections in the following:

• The MailingListView class: ADD #1 ~ 6
• The MailingListController class: ADD #1 ~ 2

The four Java files and data file can be found in my shared google drive folder: https://drive.google.com/open?id=1ZIpy4xopDYYdvP7nt_U1w9RAMAItd0TC

The following screenshots show the typical behaviors of the program:
