Thread: NEED HELP TO FIX Object oriented Program Facebook

Here is the Story, I want to make a object oriented program, and choose Facebook as an objeck...
The case :
The Facebook account has four different Type: Artist, people, shop, politic
and there are some method that I must use :
-become_fans_artist
-become_friends
-add_friends
-become_member
-support_politic
-look_list_friend (people)
-look_list_support_politic (politic)
-look_list_fans (artist)
-look_list_member (shop)

I'v updated the code.. I don't know it is right or not.. but i've tried it and no error.
I used 1 package and 5 class : facebook,people,artist,politic, and shop.

public class Facebook {   
    public static void main(String args[]){
 
		people orang1 = new people("James","Sukabirus 26","29 Februari 1992");
 
		Artist artis1 = new Artist("Jeffry Adityatama","Sukabirus","22 Februari 1990");
 
		people orang2 = new people("Tane Yoroshi","Sukapura","22 Agustus 1990");
 
		Artist artis2 = new Artist("Amru Rizaldy","Sempur Bogor","25 September 1991");
 
		shop toko1 = new shop("Shelly Shop","sukabirus");
 
		Politic politikus1 = new Politic("Risman Rangga","Bandung","22 Oktober 1966");
 
		orang2.Become_fans(artis2);
		politikus1.Become_fans(artis2);
		orang1.Become_member(toko1);
		orang2.Become_member(toko1);
		orang1.add_friend(orang2);
		orang1.support_politics(politikus1);
		artis2.Look_list_fans();
		politikus1.Look_list_supporter();
		toko1.Look_list_member();
 
	}    
}
 
public class people {
      private String name,address,born;
 
    public people(){}
    public people(String nama, String alamat, String ttl){
    this.name=nama;
    this.address=alamat;
    this.born=ttl;
    }

    public void add_friend(people t){}

    void Become_fans(Artist artis2) {
 
    }
 
    public void Look_list_supporter(){
        System.out.println("List supporter for ---: ");
        System.out.println("1.Kukung Kurniawan");
 
 
    }
}

The Question : is my method of program that using oop okay? or should be re-build/
if should, pls tell me the right construction...???

should I use Array to save the name of the people that support politic, become fans artist, become member shop???
if I should pls tell me the code.. I was confused...



The problem : when => orang2.Become_fans(artis2);
I want to display public void look_list_fans(){} that contain orang2 but I don't know how??

when => orang2.Become_member(toko1);
I want to display public void Look_list_member(){} that contain orang2 but I don't know how??

I got he problem at the method.
that can add_friends, look_list_friend.etc..


Output program that I wanted :

List Fans from Amru Rizaldy :
1.Tane Yoroshi
2.Risman Rangga

list support from Risman Rangga :
1.Kukung Kurniawan

list Member from Shelly Shop :
1.Kukung Kurniawan
2.Tane Yoroshi

I want to Become_fans(){} save the name of the people so the look_list_fans(){} coudl display it..

If the become_fans method saves the fans for an object, shouldn't the list_fans method be in the same object?
If you make the list of fans a class member, then both the become_fans and the list_fans methods would be able to access the list of fans.

If a class wants the fans for another class, then the class desiring the list of fans for the other class will have to call the class with the fans and get the list of fans from the class that has the fans.

You need to decide what class should hold the list of fans.
When you have that, then you need to provide methods to access that list.
