Package java.util.regex Description
Classes for matching character sequences against patterns specified by regular expressions.
An instance of the Pattern class represents a
regular expression that is specified in string form in a syntax similar to
that used by Perl.
Instances of the Matcher class are used to match
character sequences against a given pattern. Input is provided to matchers via
the CharSequence interface in order to support matching
against characters from a wide variety of input sources.
Unless otherwise noted, passing a null argument to a method
in any class or interface in this package will cause a
NullPointerException to be thrown.
