            // Deleting the documents
            collection.deleteOne(Filters.eq("_id", 1));
            System.out.println("Document deleted successfully...");

            try (MongoCursor < Document > cur = collection.find().iterator()) {

                while (cur.hasNext()) {

                    var doc =;
                    var users = new ArrayList < > (doc.values());

                    System.out.printf("%s: %s%n", users.get(1), users.get(2));
