cast splitStrings as int?

Hi,
I'm trying to read in data from a file, with each line containing tab-separated integers and strings. I can get the data in fine and use splitStrings to divide each line into "words" but I can't cast the words as ints - any ideas? I get an error that says "An expression of type "java/lang" cannot be cast into type "String""
Here's a code excerpt.
String words[]=splitStrings(lines[i],'\t');
println(int(words[j]));
Where j is an int < words.length
Thanks!

Processing's casts don't work on Strings (though maybe they could/should?)
Use splitInts instead...
http://processing.org/reference/splitInts_.html
Code:
int numbers[]=splitInts(lines[i],'\t');
println(numbers[j]);

Oh, and if you want to get just one int from a String you can use the standard Java class Integer to do it for you.
Code:
String numberString = "100";
int number = Integer.parseInt(numberString);
println(number);
