As of Java 1.8, you can use Files.list to get a stream:

Path findFile(Path targetDir, String fileName) throws IOException {
    return Files.list(targetDir).filter( (p) -> {
        if (Files.isRegularFile(p)) {
            return p.getFileName().toString().equals(fileName);
        } else {
            return false;
        }
    }).findFirst().orElse(null);
}
