public void listFilesForFolder(final File folder) { for (final File fileEntry : folder.listFiles()) { if (fileEntry.isDirectory()) { listFilesForFolder(fileEntry); } else { System.out.println(fileEntry.getName()); } } } final File folder = new File("/home/you/Desktop"); listFilesForFolder(folder); 

Files.walk API is available from Java 8.

try (Stream<Path> paths = Files.walk(Paths.get("/home/you/Desktop"))) { paths .filter(Files::isRegularFile) .forEach(System.out::println); } 

The example uses try-with-resources pattern recommended in API guide. It ensures that no matter circumstances the stream will be closed.

Use:

public void listFilesForFolder(final File folder) { for (final File fileEntry : folder.listFiles()) { if (fileEntry.isDirectory()) { listFilesForFolder(fileEntry); } else { System.out.println(fileEntry.getName()); } } } final File folder = new File("/home/you/Desktop"); listFilesForFolder(folder);

Files.walk API is available from Java 8.

try(Stream<Path> paths = Files.walk(Paths.get("/home/you/Desktop"))) { paths.forEach(filePath -> { if (Files.isRegularFile(filePath)) {   System.out.println(filePath); } }); }

Edit: This API is now available from Java 8.

Files.walk(Paths.get("/home/you/Desktop")).forEach(filePath -> { if (Files.isRegularFile(filePath)) { System.out.println(filePath); } }); 

public void listFilesForFolder(final File folder) { for (final File fileEntry : folder.listFiles()) { if (fileEntry.isDirectory()) { listFilesForFolder(fileEntry); } else { System.out.println(fileEntry.getName()); } } } final File folder = new File("/home/you/Desktop"); listFilesForFolder(folder);
