The iterator() method of AbstractList class in Java
The iterator() method of AbstractList class is used to return an iterator over the elements in this list in proper sequence.
The syntax is as follows
public Iterator<E> iterator()
Here, the Iterator is an iterator over a collection. To work with the AbstractList class, import the following package
import java.util.AbstractList;
The following is an example to implement iterator() method of the AbstractlList class in Java
Example
import java.util.ArrayList;
import java.util.Iterator;
import java.util.AbstractList;
public class Demo {
public static void main(String[] args) {
AbstractList<Integer>
myList = new ArrayList<Integer>();
myList.add(75);
myList.add(100);
myList.add(150);
myList.add(200);
myList.add(250);
myList.add(150);
myList.add(150);
myList.add(400);
System.out.println("Elements in the AbstractList = " + myList);
Iterator i = myList.iterator();
System.out.println("Iterating over the elements in the AbstractList =" );
while (i.hasNext()) {
System.out.println(i.next());
}
}
}Output
Elements in the AbstractList = [75, 100, 150, 200, 250, 150, 150, 400] Iterating over the elements in the AbstractList = 75 100 150 200 250 150 150 400
