Answer / Deep Kumar Singh

ListIterator is an iterator for lists that allows both forward and backward traversal, along with the ability to insert and remove elements. It provides the following useful methods: add(E e) – inserts a new element into the list, before the current position. set(E e) – replaces the current element with a new element. next() – moves the cursor to the next element. previous() – moves the cursor to the previous element. hasNext() and hasPrevious() – checks if there is an available element to move forward or backward respectively. remove() – removes the current element from the list.
