How to query from an array for a single field in mongodb JAVA DRIVER.

Question

Hello I have a collection called Movies with the following structure

Movies{ Title, Id, Characters[ {Character_name , actor_id} ] }

I am trying to query for a specific Character_name using a corresponding actor_id and id (movie). How is this possible without getting the whole list of movie characters? For example I want every Character_name Brad Pitt has played per each movie , in the form of an ArrayList.

Here is my code for creating an ArrayList of titles from Movies, how can I change this to obtain individual character names?

public static ArrayList popTitle() {

    ArrayList myList = new ArrayList();
    MongoClient mongoClient = new MongoClient(new ServerAddress(
            "localhost", 27017));
    DB db = mongoClient.getDB("test");

    BasicDBObject query = new BasicDBObject();
    query.put("Characters.actor_id", "162684857");
    DBCollection myCollection = db.getCollection("Movies");
    DBCursor cursor = myCollection.find(query);
    while (cursor.hasNext()) {
        DBObject theObj = cursor.next();


        BasicDBObject title = (BasicDBObject) theObj;
        String t = title.getString("title");
        myList.add(t);

    }



    Set<String> s = new LinkedHashSet<>(myList);
    myList.clear();
    myList.addAll(s);

    for (int i = 0; i < myList.size(); i++) {
        System.out.println(myList.get(i));
    }

    return myList;
}

Here is what I have so far. The query results are null.

public static void popCharacter() {


    ArrayList myList = new ArrayList();
    MongoClient mongoClient = new MongoClient(new ServerAddress(
            "localhost", 27017));
    DB db = mongoClient.getDB("test");
    DBCollection myCollection = db.getCollection("Movies");
    BasicDBObject query = new BasicDBObject();


    query.put("id", "10015");
    query.put("Characters.actor_id", "162684857");



    DBCursor cursor = myCollection.find(query); 

    while (cursor.hasNext()) {
        DBObject theObj = cursor.next();

        BasicDBObject title = (BasicDBObject) theObj;
        String t = title.getString("Characters.Character_name");
        System.out.println(t);

    }   
}
