OK, sorry my fault.

I was assuming that there was some kind of file format that I can write a string to a file (e.g. "i pledge allegiance to the flag") whereby the file contains the information but is not human readable, and yet I can programatically open the file and read the string back out.

Is this possible? (without doing some complicated encryptioning)

you can save it in gzip format if you want:

FileOutputStream fos = new FileOutputStream("file");
java.util.zip.GZIPOutputStream zos = new java.util.zip.GZIPOutputStream(fos);

zos.write("some string".getBytes());
zos.flush();
zos.close();

to read it use:
FileInputStream fis = new FileInputStream("file");
java.util.zip.GZIPInputStream zis = new java.util.zip.GZIPInputStream(fis);

BufferedReader reader = new BufferedReader(new InputStreamReader(zis));

String str = reader.readLine();


Also - you ca archive this by wrapping the file stream by ObjectInputStream and ObjectOutputStream

use ObjectOutputStream.writeObject(); for example
