}

private static class OpenFile implements Runnable {

    private File arquivo;

    public OpenFile(File arquivo) {
        this.arquivo = arquivo;
    }

    private void abrirArquivo(File arquivo) throws IOException {

            abrirArquivo(arquivo);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}
