Facebook4j: How to get total number of likes, comments and shares on a facebook post?

Question

I am trying to retrieve all the essential information regarding facebook posts using facebook4j.

Here is my code:

    final Reading reading1 = new Reading().since("-1 month").limit(38).fields("comments", "likes", "id", "message", "caption", "description", "created_time", "from").summary(); 
    final ResponseList<Post> feeds1 = facebook.getPosts("viratkohli", reading1);

    final Reading reading2 = new Reading().since("-1 month").fields("likes", "id", "message", "created_time", "from", "story").limit(100).summary(); 
    final ResponseList<Post> feeds2 = facebook.getPosts("viratkohli", reading2);



    for (int i = 0; i < feeds2.size(); i++) {
        // Get post.
        Post post1 = feeds2.get(i);
        // Get (string) message.
        String message = post1.getMessage();
        Date d = post1.getCreatedTime();
        String id = post1.getId();
       PagableList<Like> pl = post1.getLikes();
       String story = post1.getStory();

       System.out.println("post: "+i+": "+message);
       System.out.println("Created time: "+d.toString());
       System.out.println("id: "+id);
       System.out.println("story: "+story);
       System.out.println();
       for(Like like: pl) {
           String like_name = like.getName();
           String like_id = like.getId();

           System.out.println("like name: "+like_name);
           System.out.println("like id: "+like_id);
           System.out.println();
       }
       System.out.println("******************");

    }

        for(int j=0;j<feeds1.size();j++){
            Post post2 = feeds1.get(j);
            System.out.println(j);
            final PagableList<Comment> comments = post2.getComments();
            for(int k=0; k<comments.size(); k++) {
                // Get comment.
                Comment comment = comments.get(k);
                String id2 = comment.getId();
                String comm = comment.getMessage();
                Date d2 = comment.getCreatedTime();
                Integer co = comment.getLikeCount();

                System.out.println("Comment "+k+": "+comm);
                System.out.println("id: "+id2);
                System.out.println("created time: "+d2);

                }

            System.out.println("~~~~~~~~~~~~~");
            }

Currently, I'm able to get the following info:

max. of 100 recent posts, 25 recent likes, 25 recent comments for each post (for max. of 40 posts).

Any help on overcoming the limit issue will be greatly appreciated.

Here is the right answer:

    final Reading reading = new Reading().summary().fields("id", "message", "likes.summary(true)", "shares", "comments.summary(true)").limit(20).since("-1 month"); 
    final ResponseList<Post> feeds = facebook.getPosts("green", reading);

    for (int i = 0; i < feeds.size(); i++) {
        // Get post.
        Post post = feeds.get(i);

       Integer likesCount = post.getLikes().getSummary().getTotalCount();
        Integer sharesCount = post.getSharesCount();
       Integer commentsCount = post.getComments().getSummary().getTotalCount();

       if(sharesCount == null)
           sharesCount = 0;
       if(likesCount == null)
           likesCount = 0;
       if(CommentsCount == null)
           commentsCount = 0;
        System.out.println("No. of shares for post "+i+": "+sharesCount);
        System.out.println("No. of likes for post "+i+": "+likesCount);
        System.out.println("No. of comments for post"+i+": "+commentsCount);
        System.out.println();

If you only want the total number of likes, but not the individual likes - then set limit to 0, and summary to 1.
