I looked in the Java documentation and found:

    Interface java.io.FilenameFilter

The "Interface" bit is somwwhat of a giveaway.

To set a filter for the Filer, you must create  a class that implements
FilenameFilter. This interface includes an accept() method that returns a
boolean value indicating whether a particular file meets the filtering
specifications laid out in accept().  For example, accept() might return
true if a file has a .java extension.
