MongoDB Stats Count Different from Number of Documents

Robomongo shows that I have 50 documents in my database's collection (which is true), and yet, the console output from the following says otherwise; count() returns 4494 and so does stats(). This is causing my cursor to erroneously iterate through the collection repeatedly instead of just once.

MongoClient mongoClient = new MongoClient(DATABASE_HOST, DATABASE_PORT);

DB db = mongoClient.getDB(DATABASE_NAME);

DBCollection documentCollection = db.getCollection(COLLECTION_NAME);

DBCursor cursor = documentCollection.find();

System.out.println("Number of documents in collection: " + cursor.count());

Please help! Sincerely confused.

P.S. I have used validate() to confirm that all documents in the collection are valid. Also, documentCollection.getCount() returns the same value of 4494.

Robomongo paginates results, 50 documents per page by default.
db.COLLECTION_NAME.count() returns total number of documents in the collection.

Try with:

MongoCollection<Document> collection;
collection.count();
