You are passing a raw byte array. What it could be is a
DataOutputStream in a raw byte array.

to create such a beast see http://mindprod.com/fileio.html

You can read it with a DataInputStream.

Note when you do this your Strings will be counted UTF-8 format.
You could write them an char[] if you wanted the simplicity of 16-bit
chars.

Trying to encode binary data in Strings is asking for trouble unless
you use something very vanilla like base64.
