The result of a match operation.
A compiled representation of a regular expression.
Unchecked exception thrown to indicate a syntax error in a regular-expression pattern.
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
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.
An excellent tutorial and overview of regular expressions is Mastering Regular Expressions, Jeffrey E. F. Friedl, O'Reilly and Associates, 1997.
