The iterator() method of CopyOnWriteArrayList in Java
The iterator() method is used to return an iterator over the elements in this list.
The syntax is as follows
Iterator<E> iterator()
To work with CopyOnWriteArrayList class, you need to import the following package
import java.util.concurrent.CopyOnWriteArrayList;
The following is an example to implement CopyOnWriteArrayList class iterator() method in Java
Example
import java.util.Arrays;
import java.util.Iterator;
import java.util.concurrent.CopyOnWriteArrayList;
public class Demo {
public static void main(String[] args) {
CopyOnWriteArrayList<Integer>
arrList = new CopyOnWriteArrayList<Integer>();
arrList.add(50);
arrList.add(90);
arrList.add(150);
arrList.add(200);
arrList.add(350);
arrList.add(500);
arrList.add(650);
System.out.println("CopyOnWriteArrayList String Representation = " + arrList.toString());
Iterator i = arrList.iterator();
System.out.println("Iterating...");
while (i.hasNext()) {
System.out.println(i.next());
}
}
}Output
CopyOnWriteArrayList String Representation = [50, 90, 150, 200, 350, 500, 650] Iterating... 50 90 150 200 350 500 650
