The list
method (§22.24.26) of class File
requires, as an argument, an object
that implements the FilenameFilter
interface. The only purpose of such an
object is to provide a method accept
that decides which files should appear in the
generated directory listing.
public interfaceFilenameFilter
{ public booleanaccept
(File dir, String name); }
22.25.1 public boolean accept(File dir, String name)
This method should return true
if and only if the given file named name
in the
directory dir
is to appear in the final list of files generated by the list
method
(§22.24.26) of class File
.
