get Longitude and Latitude of Tweets (Twitter)

Hey together, We are trying to get the longitude and latitude of Tweets (with a specific hashtag) via Processing. Our problem is that we receive the GeoLocation of a Tweet in one variable but not the longitude and latitude as separated values (in order to use them for further functions).

This is an extraction of our code:

try { QueryResult result = twitterInstance.search(queryForTwitter); ArrayList tweets = (ArrayList) result.getTweets(); for (int i=0; i<tweets.size (); i++) {

  //all Tweets
  Status t = (Status)tweets.get(i);
  String user = t.getUser().getName();
  String msg = t.getText();
  GeoLocation geo = t.getGeoLocation();

} catch(TwitterException te) { println("Could not connect: " + te); } }

Has anyone a solution for us? Thanks in advance :) Marina and Thea
