Need help in Java coding

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 persons name, an image(extra credit), current status(Online, offline, busy,...), 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 and remove friends.

• You can use any data structure you have learned and wrote so far.
• DO NOT IMPORT ANY JAVA, C++ or PYTHON LIBRARY! Use your own data structures which you wrote.
• 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.
• Use at least a hash table or a dictionary( this is the most important!)
