A String is a bunch of characters. How is it supposed to be a hex value? You need to be a little more specific.31080601090620003453 -> AF547A051406147D?If so, look at the Long class.

There's no built-in function to convert a string of hex to a byte array, unfortunately. And using the Integer method it remarkably messy, because of the odd character length problem etc.. It's probably easier to write it yourself using Character.digit() with a little shifting and orring.

There's a class for it in the apache commons "Codec" library.
