It all depends on the implementation of the hashCode() method. Object returns an identity hash code, so if that implementation is used the answer is (most likely) yes.
However, I could override the hashCode() method to return a constant, e.g. 42. Now all objects of my class will have the same hash code. Granted, it's an unpracticle example, but there may be implementations that may lead to similar hash codes for different objects.
The only things you can tell about two objects if you only have their hash codes: - if the hash codes are different the objects are different - if the hash codes are the same the objects might be equal
Also read the API for Object.equals and Object.hashCode - it's an interesting read. [ August 12, 2008: Message edited by: Rob Prime ]
