There's only one native unsigned primitive: char. But you can get the functionality you need using BigInteger.

Java does not have an unsigned int and long data type.
Why exactly do you need it?

I need to represent (and manipulate) a disk address (8 bytes) which should be an unsigned long.
BigInteger as was suggested by CEHJ, looks like a possible solution - I'm checking it right now...
