There is not, and there probably never will be. With any testing framework -
if the outcome of a test A depends on whether or not test B has run before
it - then you have created for yourself (and your team) a formidable time
waster.
Everyone will spend lots of time figuring out why a test is failing under
some circumstances and not under others. Every week there is a new person on
this list asking something like:
"Why do all my (Cucumber/RSpec) tests pass when I run them all with Rake,
but not when I run one individually?"
The answer is always the same:
"Because they are coupled"
Then they go debugging for an hour, sometimes several days and come back
with:
"I finally found out where the coupling is. How can I decouple them?"
If I make it easier for people to run scenarios in a certain order, I also
make give people more rope to hang themselves with. People will inevitably
end up in the situation I just described. And then everybody's time gets
wasted.
Actually - in Cucumber - the objects created in one scenario will never be
available to the next scenario. Of course you can work around this (shoot
yourself in the foot) by storing state in static/class variables or in a
database, but I don't recommend it.

I think I understand what you're after.
Hooks are not yet implemented in cucumber_java (but it would be fairly easy
to implement). If you think this
is what you need - please create a ticket in cucumber_java's github tracker.
But maybe Background is a better fit in this case?
http://wiki.github.com/aslakhellesoy/cucumber/background
It should work fine with cucumber_java.
