Question

Workign on a Java Project, very similiar if you think about it like facebok or Myspace but just a project.

Each person in the network should have a profile that contains: Name, Current status, and a list of friends

You should allow a person to join the network, leave the network, create a profile, modify their profile, search for other profiles, and add friends.

Please note that both the social network and the list of friends for each person are collections.

Here is what I have to offer as a structure:

import java.awt.image.*;
import java.util.ArrayList;

public class Driver
{
   public static void main(String[] args)
   {
       System.out.println("Creating profiles and adding to database.");
       Manager m = new Manager();

       Profile john = new Profile();
       john.setFirstName("John");
       john.setLastName("Doe");
       john.setStatus("My name is John.");

       Profile jane = new Profile();
       jane.setFirstName("Jane");
       jane.setLastName("Doe");
       jane.setStatus("My name is Jane.");

       Profile billy = new Profile();
       billy.setFirstName("Billy");
       billy.setLastName("Bob");
       billy.setStatus("My name is Billy Bob!");

       m.addProfile(john);
       m.addProfile(jane);
       m.addProfile(billy);
       m.display();

       System.out.println("------------------------------------- ");
       System.out.println("Creating friendships. ");

       m.createFriendship(john, jane);
       m.createFriendship(jane, billy);

       m.display();

       System.out.println("------------------------------------- ");
       System.out.println("Removing John. ");
       m.removeProfile(john);

       m.display();
   }
}

import java.awt.image.*;
import java.util.ArrayList;

public class Manager
{
   ArrayList allProfiles;

   public Manager()
   {
       allProfiles = new ArrayList ();
   } // end default constructor

   public void addProfile(Profile p)
   {
       allProfiles.add(p);
   } // end addProfile

   public void removeProfile(Profile p)
   {
       for (int x = 0; x < allProfiles.size(); x++)
       {
           allProfiles.get(x).removeFriend(p);
       } // end for loop
       allProfiles.remove(p);
   } // end removeProfile

   public void createFriendship(Profile a, Profile b)
   {
       a.addFriend(b);
       b.addFriend(a);
   } // end createFriendship

   public void display()
   {
       for (int x = 0; x < allProfiles.size(); x++)
       {
           allProfiles.get(x).display();
           System.out.println();
       } // end for loop
   } // end display;
}

import java.awt.image.*;
import java.util.ArrayList;

public class Profile
{
   BufferedImage profilePicture;
   String firstName, lastName;
   String status;
   ArrayList friends;

   public Profile()
   {
       profilePicture = new BufferedImage(150, 150, BufferedImage.TYPE_INT_RGB);
       firstName = "";
       lastName = "";
       status = "";
       friends = new ArrayList ();
   } // end default constructor

   public BufferedImage getProfilePicture()
   {
       return profilePicture;
   } // end getProfilePicture

   public void setProfilePicture(BufferedImage b)
   {
       profilePicture = b;
   } // end setProfilePicture

   public String getName()
   {
       return firstName + " " + lastName;
   } // end getName

   public String getFirstName()
   {
       return firstName;
   } // end getFirstName

   public void setFirstName(String name)
   {
       firstName = name;
   } // end setFirstName

   public void setLastName(String name)
   {
       lastName = name;
   } // end setLastName

   public void setStatus(String stat)
   {
       status = stat;
   } // end setStatus

   public String getStatus()
   {
       return status;
   } // end getStatus

   public ArrayList getFriends()
   {
       return friends;
   } // end getFriends

   public void addFriend(Profile p)
   {
       if (!friends.contains(p))
           friends.add(p);
   } // end addFriend

   public void removeFriend(Profile p)
   {
       friends.remove(p);
   } // end removeFriend

   public String toString()
   {
       return "Name: " + getName() + " Status: " + getStatus() + " Picture: " + getProfilePicture().toString().substring(0, 20) + " # of friends: " + friends.size() + " ";
   } // end toString

   public void display()
   {
       System.out.print(toString());
       System.out.println("Friends:");
       for (int x = 0; x < friends.size(); x++)
           System.out.println(" " + friends.get(x).getName());
   }
} // end Profile

Explanation / Answer

yes good ... creating profile and adding to database . but you can use exception to avoid error in the execution. you created entry form and adding friends and removing friends.
