Answer 1

Do this -

 MongoClient client = new MongoClient();
    DBObject resultObject  = new BasicDBObject("_id", username);
    MongoDatabase database = client.getDatabase("DBNAME");
    MongoCollection collection =  database.getCollection("COLLECTION_NAME");
    DBObject dbObject  = new BasicDBObject("_id", username);
    resultObject   = collection.find(dbObject).next();
    String result =  resultObject.get(YOUR_COLOUM_NAME);
