        try (InputStream source = archive.getEntries().get(0).open()) {
            byte[] b = new byte[1024];
            int bytesRead;
            while (0 < (bytesRead = source.read(b, 0, b.length))) {
                destination.write(b, 0, bytesRead);
            }
        }
    }
} catch (IOException ex) {
    System.out.println(ex);
}

    try (FileOutputStream destination = new FileOutputStream(dataDir + "firstEntry.txt")) {
        archive.getEntries().get(0).extract(destination, "p@s$w0rd");
    }
} catch (IOException ex) {
    System.out.println(ex);
}
