Using Java

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 and remove friends.

• Use at least a hash table or a dictionary
• You need at least 2 data structures: One for profiles and one for the list of the friends of those profiles.
• You need to implement CRUD (In computer programming, create, read, update, and delete (CRUD) are the four basic functions):
  • C= Create: Add profile- Add friends
  • R= Read: Read the information of a profile - Search for other profiles
  • U= Update: Update and edit the profile - Update the friend list
  • D= Delete: Delete a profile - Delete a friend of a profile.
• You need to have a class diagram for your program (A simple one is acceptable):
  • Read about UML and Class Diagrams online:

  • Draw it on paper or a file (both are acceptable): (Links to an external site.)
