Use "\t" as the delimiter, like:

I agree with Blake. This code works fine for me:

Interestingly, "\\t" also works fine.

"\t" is a single tab character. "\\t" means the regular expression "\t" which also is a single tab character. Slight difference, same result.

Just for others to make it work.. use one space before \t.
e.g.

No, don't do this for the following reasons:

1. It isn't necessary. If you want to split on a tab then specifying \t works fine.
2. It's wrong. It will change the way the string splits from just splitting on tabs to splitting on both tabs and whitespace.

If you don't believe me run this code.


BTW you shouldn't use StringTokenizer, the API docs say "StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead."
