Fwd: kiri - tech - Iterator pitfall

Iterator pitfall?

 

List lst = new ArrayList();

        lst.add("Hi");

        lst.add("Hello");

        while (lst.iterator().hasNext()) {

            System.out.println(lst.iterator().next());

        }

 

This will run infinitely as it will try to get next element each time which actually gives first element each time.

Hence have to create a different Iterator object.

 

Iterator itr = lst.iterator();

        while (itr.hasNext()) {

            System.out.println(itr.next());

        }

 

 Thanks
