Hi,

I am a fairly new programmer using processing and I was wondering if anybody knew how to print the contents of a hashmap, in this case tweets, to the screen within a loop? It seems to be no problem to print to the console but it seems a bit trickier to print to the screen. Here is an extract from the code so far with the problem area in bold:

Line 137: Twitter twitter = new TwitterFactory().getInstance();
              HashMap<Long,Tweet> tweets=new HashMap<Long,Tweet>();

...


Line 233: public void searchTwitter(String searchQuery) {
              twitter4j.Query query = new twitter4j.Query(searchQuery);
              query.rpp(100);
              Date referenceDate=new Date();
              for(int i=0; i<NUM_SEARCHES; i++) {
              String d=new SimpleDateFormat("yyyy-MM-dd").format(referenceDate);
              query.until(d);
              try {
             QueryResult result = twitter.search(query);
             for (Tweet tweet : result.getTweets()) {
             if (tweets.get(tweet.getId())==null) {
             GeoLocation loc=tweet.getGeoLocation();
              if (loc!=null) {
                tweets.put(tweet.getId(),tweet);
              }
            } else {
              //println("skipping: "+tweet.getId());
            }
          }
        }
        catch(TwitterException e) {
          println(e.getMessage());
        }
        referenceDate.setTime(referenceDate.getTime()-TIME_STEP*DAY_DURATION);
      }
    }

...

Line 268: public void draw() { 
              for(Tweet tweet : tweets.values()) {
              GeoLocation loc=tweet.getGeoLocation();
              Vec3D p=new    
              Vec3D(600,radians((float)loc.getLongitude())-HALF_PI,radians((float)loc.getLatitude())).toCartesian();
             // create a box at the computed position
             AABB box=new AABB(p,2);
             noStroke();
             fill(255,120,0);
            // draw box at position
            gfx.box(box);
             print(tweet); - so this prints the tweets to the console in the loop but replacing print with text and an x and y
            position throws an error...
            fill(255);

Any insights would be great
