I have problem iterating through String Array with table.matchRows command. I got the constructor from here but it doesn't seem to work. The APlett says "Can only iterate over an array of an instance of jave.lnag.iteravle 

Here is the code. The error occur on the line 68. I'm trying to count the repetitions of the same words in the text snatch from Reuters XML. 

Please assist.

I implemented arrayList to store Strings down the code. I didn't know the size so instead pure Array I implemented the list. I was looking for the way to convert objects from the arrayList to Strings and found how convert the Object to String. At the line  34 PApplet gives me a message "cannot convert from Object[] to String[]. 

I'm trying sort out the words from XML feed and analyze vocabulary. Could you please help me with arrayList converting.
