Recursively list all files within a directory using nio.file.DirectoryStream;
Java 8 provides a nice way for that:
Files.walk(path)This method returns Stream<Path>.
Make a method which will call itself if a next element is directory
void listFiles(Path path) throws IOException { try (DirectoryStream<Path> stream = Files.newDirectoryStream(path)) { for (Path entry : stream) { if (Files.isDirectory(entry)) { listFiles(entry); } files.add(entry); } }}
Check FileVisitor, very neat.
Path path= Paths.get("C:\\Users\\Danny\\Documents\\workspace\\Test\\bin\\SomeFiles"); final List<Path> files=new ArrayList<>(); try { Files.walkFileTree(path, new SimpleFileVisitor<Path>(){ @Override public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException { if(!attrs.isDirectory()){ files.add(file); } return FileVisitResult.CONTINUE; } }); } catch (IOException e) { e.printStackTrace(); }
