I have a Stack object and I want to make another instance of a Stack object but with the same values as the existing one, how do I do this?
the Stack object does not support a constructor so is there an easy way?

I haven't tried this, but I assume you can use the clone() method from Vector, which is the super class of Stack.
Otherwise, you can always call toArray() and add the elements to the new Stack one by one in a for loop.

Collections.copy(List src, List dest);
List.addAll (Collection c);
