Streams are fast and very easy to read:

final Path rootPath = Paths.get("/tmp");

// All entries Path objects
ArrayList all = Files
        .list(rootPath)
        .collect(Collectors.toCollection(ArrayList::new));

// Only regular files at Path objects
ArrayList regularFilePaths = Files
        .list(rootPath)
        .filter(Files::isRegularFile)
        .collect(Collectors.toCollection(ArrayList::new));

// Only regular files as String paths
ArrayList regularPathsAsString = Files
        .list(rootPath)
        .filter(Files::isRegularFile)
        .map(Path::toString)
        .collect(Collectors.toCollection(ArrayList::new));
