AbstractSequentialList iterator() method in Java is used to get an Iterator or List Iterator over a list. It returns an iterator over the elements in this list (in proper sequence). This method overrides iterator() in class AbstractList<E>
Syntax:
public Iterator<E> iterator()
Return Value: This method returns an iterator over the elements in this list (in proper sequence).
Below is the code to illustrate iterator() method:
Program 1:
// Java program to demonstrate// iterator() method  import java.util.*;  public class GfG {      public static void main(String[] args)    {        // Creating an instance of the AbstractSequentialList        AbstractSequentialList<Integer> absl = new LinkedList<>();          // adding elements to absl        absl.add(5);        absl.add(6);        absl.add(7);        absl.add(2, 8);        absl.add(2, 7);        absl.add(1, 9);        absl.add(4, 10);          // Getting Iterator        Iterator<Integer> Itr = absl.iterator();          // Traversing elements with help of iterator        while (Itr.hasNext()) {            System.out.print(Itr.next() + " ");        }    }} |
Output:
5 9 6 7 10 8 7
Program 2:
// Java program to demonstrate// iterator() method  import java.util.*;  public class GfG {      public static void main(String[] args)    {        // Creating an instance of the AbstractSequentialList        AbstractSequentialList<String> absl = new LinkedList<>();          // adding elements to absl        absl.add("Geeks");        absl.add("ForGeeks");        absl.add("A");        absl.add("Portal");        absl.add(3, "Computer Science");        absl.add(5, "For Geeks");          // Getting Iterator        Iterator<String> Itr = absl.iterator();          // Traversing elements with help of iterator        while (Itr.hasNext()) {            System.out.println(Itr.next());        }    }} |
Output:
Geeks ForGeeks A Computer Science Portal For Geeks
