Regular expressions as string delimiter?

[chad]

We can simply construct a StringTokenizer by calling the constructor
that takes the String to be parsed and the string that represents the
delimiter.

But, suppose that I have a String like this:

"The university library has a collection of 237 books published in the
1830's in the United Kingdom."

I want to use, among others, the numeric numbers such as 237 and 1830
as delimiters also. Is such a delimiter possible in Java?

The best solution to this is new as of jdk 1.5... The new
java.util.Scanner class is really an amazing improvement over all the
the previous formatted input classes in java. It's much more powerful
than StringTokenizer, and slightly more powerful

With jdk 1.4, you can use the split() method on Strings to get an array
based on a regular expression.

With jdk 1.3 and earlier, the standard libraries don't have anything to
support that, so you'll have to either write your own system, or use an
external product.

Oops, that'll teach me to get distracted while sending out a message...

Finishing that thought:

It's much more powerful than StringTokenizer, and slightly more powerful
than StreamTokenizer with a *much* better API.

Actually, that helps me too. I am currently using JDK 1.3, and
am currently working on something like a tokenized stream.

Thanks for finishing the thought.
