filtering out users using TwitterUtils

Is there a way to extract only specific user who post a tweet when using TwitterUtils.createStream()? (JAVA) The "filters" argument specifies the strings that need to be contained in the tweets, but I am not sure how this can be used to specify the user who interest me. i have this :

String[] filters = { "#USA" };
    JavaDStream<Status> tweets = TwitterUtils.createStream(ssc,filters);

this give me tweets which contains "#USA" what i need is a way to listen to a specific user and see what he post .

thanks

private void receive() {
    try {
        TwitterStream newTwitterStream = new TwitterStreamFactory()
                .getInstance(twitterAuth);
        newTwitterStream.addListener(new StatusListener() {

            public void onException(Exception e) {
                if (!arret) {
                    restart("Erreur pandant la reception des tweets", e);
                }

            }

        } else{
            newTwitterStream.sample();
        }
        setTwitterStream(newTwitterStream) ; 
        arret = false ; 

    } catch (Throwable t) {
        // En cas d'erreur on redémare le streaming 
        restart("Erreur pendant la reception des données ", t);
    }
