I have two threads and both want to share some information without any synchronization,
1)is it possible?
2) if possible,please explain How?

sorry to give less details

The java tutorial has a part on concurrency (here) which you should read. It covers all the aspects about threading and synchronization.

First, I would recommend getting very comfortable with using threads and synchronization first. Once you get really really comfortable, then you can start learning how to do optimistic locking algorithms.

Lock-less synchronization can get really hairy -- not for the faint of heart.... but... if you want to play around with it, take a look at the java util concurrent atomic classes.
