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.
