Currently we are writing as shown below. Is there any better

Answer 1

Here is a short and easy way. It creates a file and writes the data relative to your code project:

private void writeToFile(String filename, String data) {
    Path p = Paths.get(".", filename);
    try (OutputStream os = new BufferedOutputStream(
        Files.newOutputStream(p, StandardOpenOption.CREATE, StandardOpenOption.APPEND))) {
        os.write(data.getBytes(), 0, data.length());
    } catch (IOException e) {
        e.printStackTrace();
    }
}
