i have an int (unknown lenght) that i need to format so there's a comma every 3 digits, like "1,000,203,2203". I know about DecimalFormat df1 = new DecimalFormat(), but I'm not quite sure what to put in the parentheses. If I knew the int was 4 digits, I could do "0,000", but I'm not sure how to go about formatting an unknown number of digits. Let me know!
Thanks!

You're on the right track, just use #'s instead of 0's in you DecimalFormatter, like this:
If the number is more than 6 digits, it will automatically stick in another "," at the right places so you don't have to guess at the size.
Try it out and you'll see what I mean.
