10.Java获得目录列表

File dir = new File("directoryName");String[] children = dir.list();if (children == null) {// Either dir does not exist or is not a directory} else {for (int i = 0; i < children.length; i++){// Get filename of file or directoryString filename = children[i];}}// It is also possible to filter the list of returned files.// This example does not return any files that start with `.'.FilenameFilter filter = new FilenameFilter() {public boolean accept(File dir, String name) {return !name.startsWith(".");}};children = dir.list(filter);// The list of files can also be retrieved as File objectsFile[] files = dir.listFiles();// This filter only returns directoriesFileFilter fileFilter = new FileFilter() {public boolean accept(File file) {return file.isDirectory();}};files = dir.listFiles(fileFilter);
