I want to return the results from the find query with the help of sortaing based on lastUpdated field .

Currently i have seen two ways

First Approach

BasicDBObject query = new BasicDBObject();
query.put("updated_at","-1");
query.put(MONGO_ATTR_SYMBOL, "" + symbol);
DBCursor cursor = DBcollection.find(query).sort(query);

Second Approach 

DBCursor cursor = DBcollection.find(query,new BasicDBObject("sort", new BasicDBObject("lastUpdated ", -1)));

What is the best option to work with any ideas ??

java mongodb
