ArrayList: Iteration using ListIterator
Explore how to iterate over an ArrayList using the ListIterator interface in Java. Learn to move forwards and backwards through a list, modify elements during iteration, and safely insert or remove items. Understand the benefits over a simple Iterator and why using parameterized types avoids runtime errors like ClassCastException.
We'll cover the following...
ListIterator
The Iterator provides very limited capabilities as we can iterate only in the forward direction and we can’t update or insert an element to the list while iterating. To overcome these problems, we can use ListIterator. The listIterator() method returns an object of type ListIterator which can then be used to iterate the ArrayList.
Below are the methods that are available in the ListIterator interface.
-
hasNext()— This method is used to check if there is a next element in the list when the list is iterated in the forward ...
