FileFilter

  • FileFilter is an interface used for filtering abstract pathnames, primarily for use with the listFiles() method of the File class.

  • Implementations of the FileFilter interface must provide an accept() method that determines whether a given File object should be included in a list.

  • The accept() method takes a File object as input and returns true if the file should be included in the list, otherwise false.
