Examples of java.util.Scanner.match()

java.util.Scanner.match()
Returns the match result of the last scanning operation performed by this scanner. This method throws IllegalStateException if no match has been performed, or if the last match was not successful.
The various nextmethods of Scanner make a match result available if they complete without throwing an exception. For instance, after an invocation of the {@link #nextInt}method that returned an int, this method returns a MatchResult for the search of the Integer regular expression defined above. Similarly the {@link #findInLine}, {@link #findWithinHorizon}, and {@link #skip} methods will make amatch available if they succeed. @return a match result for the last match operation @throws IllegalStateException If no match result is available
