How to read all files in a folder from Java?

Answer 1

Just walk through all Files using Files.walkFileTree (Java 7)

Files.walkFileTree(Paths.get(dir), new SimpleFileVisitor() {
    @Override
    public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
        System.out.println("file: " + file);
        return FileVisitResult.CONTINUE;
    }
});
