I have a function that receives an Iterator. I need to iterate through the list of elements more than once in the same routine. However, once I've used the iterator once, there is no way to get back to the first element. I could pass in the Container instead of just an Iterator, but I would prefer not to. In C++, I would just copy the iterator, but I can't (or don't know how to) do this in Java.

Suggestions?

For those to whom code says more than words, an example:

			

			boolean frabulateTheFoobars(Iterator it) {
			

			// first make sure all the Foobars are tasty
			

			while (it.hasNext()) {
			

			Foobar foobar = (Foobar) it.next();
			

			if (!foobar.isTasty()) {
			

			return false; // these Foobars can't be frabulated
			

			}
			

			}
			

			

			

			

			// do what we came here for
			

			while (it.hasNext()) {
			

			Foobar foobar = (Foobar) it.next();
			

			foobar.frabulate();
			

			}
			

			

			return true;
			

			}
			

		

Much thanks,

Eric
