This is probably really simple, but is there a way to search a string for a word in an if statement?

EDIT:

I got this working. Is there a way to search for multiple words?
2. if(entry.getTitle().contains("green latern")){
3. chooser=0;
4. }
5. else{
6. chooser=1;

random text array and updating the setup

I'm making a twitter script but I need it to randomly select a string and search it. The problem is that the search is in the setup. Is there a way to make the setup update? so that the search reloads a different keyword. I've attached my script. The important stuff is in the feeder creator.
I've tried placing the feeder into an void update(), but the i can't get at the information in the draw().

how do you harvest information from twitter?

I've been able to do simple things like GetTitle() or GetLinks(), but I'm looking to get the location which is under <twitter:place_type> in the twitter API. I think its just a matter of telling processing to draw from a specific xml element. Is this something that needs to be done in prohtml?

I can't figure out why this won't align my text from the center of the ellipse out at a 45 degree angle. I think its a problem with me setting up the axis at the center of the circle.

I been working on a script that takes an rss feed's links and and searches through the data on those link pages. but because prohtml's htmlList.printElements(); returns a void instead of a string. Is there a way to convert this to a string so I can use an if() to find keywords? Or is there a better way to search through the data? I've included my code.
