The class is java.util.regex.Pattern, Java's implementation of the powerful regular expression pattern-matching mechanism. Regex patterns can be fairly complicated, so read the details of building a regular expression in the above document closely.

I wrote a couple of introductory articles on Regular Expressions in Java 1.4 that you might find useful.
Take a look at An Introduction java.util.regex Part I and Part II.
Good luck.
