getFollowerIDs / FriendsIDs questions



I am a bachelor student from germany. Currently i am trying to use twitter for prediction task and
I have a few questions:

  1. I use twitter4j and it seems that there is no possibility to get follower/friend lists of user from the
    status object of “onstatus” method. I use the authentication credentials early to build the stream and
    can not open another “twitter” object afterwards to get follower / friend lists.
    is this correct or is there a way?
    (I would have to close the stream, open a twitter object, get infos for userID and then restart the stream, which is very… circumstantial.)
  2. Is there a possibility to get more than 15 requests / 15 mins for research application?
