Design and implement a Java 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, 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. Although you will have some freedom in the design of the data types, please note that both the social network and the list of friends for each person need to be implemented using the concepts studied in our course. Note that in Week 7 we will study new elements and you can also apply them in your implementation. Create a UML class diagram that describes your class designs. Explain in a separate document why you chose the ADTs you used in the design of the data structures
