我的问题是如何计算每个朋友的权重总和这是我的java代码：

import com.restfb.Connection;
import com.restfb.DefaultFacebookClient;
import com.restfb.FacebookClient;
import com.restfb.types.Post;
import java.io.*;
import java.util.Calendar;
import java.util.Date;
import java.util.List;
import java.util.Optional;

public class main {

    public static void main(String[] args) throws IOException {
       String accessToken ="EAACEdEose0cBANEXpFEXQZALRTI8k84B2po0w";
       FacebookClient fbclient = new DefaultFacebookClient(accessToken);
       Connection<Post> result = fbclient.fetchConnection("me/feed",Post.class );
       int counter = 0;
  for(List<Post> page : result)
  {
        for(Post aPost : page)
            {    
                 Calendar c = Calendar.getInstance();
                 Calendar a = Calendar.getInstance();
                 a.add(Calendar.YEAR, -10);
                 Date Fin = a.getTime();
                 Date db = c.getTime();
                 Date time = aPost.getCreatedTime();
                 double CONST_DURATION_OF_DAY = 1000l * 60 * 60 * 24;
                 double diff = Math.abs(db.getTime() - time.getTime());
                 double numberOfDay = Math.round((diff/CONST_DURATION_OF_DAY) * 
                  100) / 100;
                 double numberofyear = (double) Math.round((numberOfDay/356) * 100) 
                  / 100;
                double dbwint = (100-(numberofyear*10))/100 ;
                double Wint  = (double) Math.round( dbwint * 100) / 100;

      if(!time.before(Fin))
       {

System.out.println("created time     "+time+"\r\n");
System.out.println("Id Poste: fb.com/"+aPost.getId()+"\r\n");
System.out.println("le poid de l'interaction Wint  "+Wint+"\r\n");
Optional.ofNullable(aPost .flatMap(post -> Optional.ofNullable(post.getLikes()))
    .flatMap(likes -> Optional.ofNullable(likes.getData()))
    .ifPresent(likes -> likes.stream()
    .map(likeItem -> Optional.ofNullable(likeItem.getName()))
    .forEach(optName -> optName.ifPresent(name ->
     System.out.println(name + "\r\n"))));

System.out.println("==================================="+"\r\n");

counter++;

       }
 else {System.out.println("date hors période"+"\r\n");}

}
  System.out.println("number of results"+counter);

}
  }
   }
    }

输出java：计算每个朋友的重量
