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.
