You're currently trying to interpret the bytes as if they were text encoded using the platform default encoding (UTF-8, ISO-8859-1 or whatever). That's not what you actually want to do at all - you want to convert it back to hex.

For that, just look at the converter you're using for the parsing step, and look for similar methods which work in the opposite direction. In this case, you want printHexBinary :

String f2 = DatatypeConverter.printHexBinary(bytes);

Try something like this:

String s = Byte.toString((byte)0x63) ;

Why you are using DatatypeConverter?

        String f="FF00000000000000";

        String f2= new String (f.getBytes());
        System.out.println(f2.toString());
