Is there a new Java 8 way of retrieving the file extension?

Question

String fileName = \"file.date.txt\";
String ext = fileName.substring(fileName.lastIndexOf(\'.\') + 1);

System.out.printf(\

No there is no more efficient/convenient way in JDK, but many libraries give you ready methods for this, like Guava: Files.getFileExtension(fileName) which wraps your code in single method (with additional validation).
