 File dir = new file ("DirectoryName");     String[] Children = dir.list (); if (children = = null) {//either Dir does not exist or was not a directory} else {for (int i=0; I &l T Children.length;         i++) {//Get filename of file or directory String filename = children[i];     }}//It is also possible to filter the list of returned files.     This example does no return any files that start with '. '. FilenameFilter filter = new FilenameFilter () {public Boolean accept (File dir, String name) {return!
