The sun tutorial is a good place to start...

http://java.sun.com/docs/books/tutorial/essential/regex/

Personally, I learn regex from Perl, and found their tutorial to be more complete -- although not related to Java...

http://perldoc.perl.org/perlretut.html

And of course, there is a website devoted to all things regex...

http://www.regular-expressions.info/tutorial.html

I read the above expression as "match any digit followed by 1 white space".
