title: Filtered the last user tweets with TwitterStream
body: <p>I have created a twitterStream in twitter4j java Api, with which I want to track down user's status. I got a list of users which is actually the followIDs.  In listener actually I download user's status images. I save my images with the following name:</p>
  
  <pre><code>String ImageUniqueFileName = status.getUser().getId()+"_id_"+CreateUniqueFileName();
  ImageUniqueFileName = ImageUniqueFileName + ".jpg"; 
  </code></pre>
  
  <p>I ve noticed that in saved images, I got several user ids which was not in the initial list followIDs. Is it normal that I track down ids from other users? Second question, how is it possible to track down not all user tweets but just the last 200 user tweets in twitterStream?</p>
  
  <pre><code>TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();
  twitterStream.addListener(listener);
  
  FilterQuery fq = new FilterQuery();
  // fq.track(myQueries);
  fq.follow(followIDs);
  twitterStream.filter(fq);     
  ArrayList&lt;FilterQuery&gt;  list = new ArrayList&lt;FilterQuery&gt;();
  list.add(fq);
  </code></pre>
