Signals
a
syntax error in the text representation of a regular expression. An
exception of this type may be thrown by the Pattern.compile(
) and Pattern.matches( ) methods, and
also by the String matches( ),
replaceFirst( ), replaceAll( )
and split( ) methods which call those
Pattern methods.
getPattern( ) returns the text that contained the
syntax error, and getIndex( ) returns the
approximate location of the error within that text, or -1, if the
location is not known. geTDescription( ) returns
an error message that provides further detail about the error. The
inherited getMessage( ) method combines the
information provided by these other three methods into a single
multiline message.
