As from release 1.4, Java 2 comes with a regular expression class that supports patterns similar in style to Perl regular expressions. This module gives you a brief introduction to regular expressions if you're not already familiar with them, then covers Java-specific topics such as compile and match methods, Pattern objects and PatternSyntaxExceptions.

Over the years I've been teaching people about Regular Expressions, I've learnt what does and doesn't work in such tuition. A casual question I saw yesterday got me writing, and I've just posted up a new technical article to the solution centre - see here (it will open in a separate window).
