Iterator is super class of ListIterator.
Here are the differences between them:
iterator you can move only forward, but with ListIterator you can move backword also while reading the elements.ListIterator you can obtain the index at any point while traversing, which is not possible with iterators.iterator you can check only for next element available or not, but in listiterator you can check previous and next elements.listiterator you can add new element at any point of time, while traversing. Not possible with iterator.listiterator you can modify an element while traversing, which is not possible with iterator.Iterator look and feel:
public interface Iterator<E> {
boolean hasNext();
E next();
void remove(); //optional-->use only once with next(),
dont use it when u use for:each
}
ListIterator look and feel:
public interface ListIterator<E> extends Iterator<E> {
boolean hasNext();
E next();
boolean hasPrevious();
E previous();
int nextIndex();
int previousIndex();
void remove(); //optional
void set(E e); //optional
void add(E e); //optional
}
