Hi,
- Shallow copy means copy only intermediate objects, pointers, references, handles etc and is created very fas.
- copies this object refer to the same object, change in its state will be visible in all copies of this object.
- deep copy means real object copy, it take more times and resources but object and his copy are independent of each.
- Object changes have no effect on the copies
Sorry for my English i know that is not perfect.

Ok, had my fun, a little more constructive:
Dawid has said it all, but keep in mind, for the non fast (i.e. deep copy) make sure to implement Cloneable interface and override the clone() method.
