Java ArrayListlistIterator() Method
Example
Use aListIterator to loop forward and backward through a list:
import java.util.ArrayList;import java.util.ListIterator;public class Main { public static void main(String[] args) { // Make a collection ArrayList<String> cars = new ArrayList<String>(); cars.add("Volvo"); cars.add("BMW"); cars.add("Ford"); cars.add("Mazda"); // Get the iterator ListIterator<String> it = cars.listIterator(); // Loop through the list while(it.hasNext()) { System.out.println(it.next()); } System.out.println("---"); // Loop backwards through the list while(it.hasPrevious()) { System.out.println(it.previous()); } }}Definition and Usage
ThelistIterator() method returns aListIterator for the list.
