Get the number of likes of a post on an FB page using RestFB API

Question

I am trying to retrieve all the posts, the number of likes on each post, the comments on each post and the number of likes of each comment from a particular FB page (https://www.facebook.com/JnuConfessions). I am using RestFB to do this.

While I have managed to get the post content, comments content and comments likes correctly, I am not able to get the number of likes of any post. I use the following code

Page page = facebookClient.fetchObject("jnuConfessions", Page.class);
Connection<Post> myPagePost = facebookClient.fetchConnection(page.getId() + "/posts", Post.class);
for (List<Post> myFeedConnectionPage : myPagePost) {
   for (Post post : myFeedConnectionPage) {
      System.out.println ("Number of likes: " + post.getLikesCount());
   }
}

However for every post, I just get a null value instead of the correct number of likes.

Is there some way to get the number of likes of each post correctly?

Try this, You should pass the parameters whichever you need.

            for (List<Post> myFeedConnectionPage : myFeed) {
                for (Post post : myFeedConnectionPage) {
                    //JSONObject userPosts = new JSONObject();

                    try {
                        post = facebookClient
                                .fetchObject(
                                        post.getId(),
                                        Post.class,
                                        Parameter
                                                .with("fields",
                                                        "from,actions,message,story,to,likes.limit(0).summary(true),comments.limit(0).summary(true),shares.limit(0).summary(true)"));
                    System.out.println ("Number of likes: " + post.getLikesCount());
                    } catch (Exception e) {
                        e.printStackTrace();

                    }
                }
            }
