I've got a problem.
I need to avoid writing a file to disk in anyway. Instead I need to use some way of memory representation of a file. Is there a output stream class that I can use to prevent disk writing at all?

Check out ByteArrayOutputStream and/or StringWriter.

Jakarta Commons IO is a library of utilities to assist
with developing IO functionality.
IOUtils.toByteArray(Reader input) will return an in-memory
representation of your file as a byte array.
