    -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();
     
    	}    
    }

    What is the current output from the program?

    If you are getting compiler errors, they need to be fixed first.
    Copy and post the full text of the error messages here.

    I got no error
    Please post your code that does not get any errors. The code you posted has many errors in it.

    how to save the people name,address, and born??
    The People class saves what is passed to it in class variables.

    pls look at the people class there is a method : become_fans(Artist A){}
    and the class Artist method look_list_fans..

    what I was trying is to get the relation on that method, become_fans(){} save data people who fans the Artist,
    and the look_list_fans(){} is method that display the list of the fans,

    but I can't make it into a code program any advice or idea??

    What do you want the Become_fans() method to do with the argument that is passed to it?
    Should it save that argument in a list that the look_list_fans() method would use?

    Yes that sounds like a way to do it.
    An ArrayList would be a good place to save the data.

    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.
