    public static void main(String[] args) {
        DataReader reader = new TwitterFollowerReader(API_KEY, API_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET, USERNAME);
        DataWriter writer = new StreamWriter(System.out);

        Job.run(reader, writer);
    }
}

2. Username of the twitter user is stored in USERNAME field.
3. TwitterFollowerReader is created to search followers of any Twitter user.
