Any numeric primitive is 'hex', so I'm not sure what you mean here.
You could simply do
byte myByte = 0xFF;
To send things to the serial port, you need to look at the JavaComm API
http://java.sun.com/products/javacomm/
This uses OuputStreams for writing, which are geared around writing streams
of bytes, which you can represent in hex.
