} Important: 1. You should submit all files you used in your program (Please do not zip them) 2.
Name your diver (main) file "Driver". I need this file to run your code and test it. 3. You should
submit the UML for your program started from your driver (main) file. Data Abstract &
Structures - CIS 22C Final Project The popular social network Facebook TM was founded by
Mark Zuckerberg and his classmates at Harvard University in 2004 . At the time, he was a
sophomore studying computer science. You already did this part for your midterm part 1: Design
and implement an application that maintains the data for a simple social network. Each person in
the network should have a profile that contains the person's name, an image(optional), current
status, and a list of friends. Your application should allow a user to join the network, leave the
network, create a profile, modify the profile, search for other profiles, and add friends. Repeat
the Project above to create a simple social network. Use a graph to track friend relationships
among members of the network. Add a feature to enable people to see a list of their friends'
friends. Reference: Data Structures and Abstractions with Java, Frank M. Carrano, 4th Edition,
