Question

It's important project. I need a help. Will give up vote for helping! Please use Java !!!!!

Need clearly written java program code and sample output!!!!!!

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. 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, optional image, 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. [Project 16 Chapter 13 - A List Implementation That Uses an Array] Repeat Project above to create a simple social network. Use a graph to track the friend relationships among members of the network. Add a feature to enable people to see a list of their friends’ friends. [Project 9 Chapter 29 - Graph Implementations]
