list iterator code example

Example 1: ArrayList listIterator() method in java

import java.util.ArrayList;
import java.util.ListIterator;
public class ArrayListListIteratorMethodExample
{
   public static void main(String[] args)
   {
      ArrayList<String> al = new ArrayList<String>();
      al.add("plum");
      al.add("apple");
      al.add("orange");
      al.add("mango");
      al.add("pineapple");
      System.out.println(al);
      ListIterator<String> iterate = al.listIterator(1);
      while(iterate.hasNext())
      {
         String str = iterate.next();
         System.out.println(str);
      }
   }
}

Example 2: set method in listiterator in java

import java.util.ArrayList;
import java.util.ListIterator;

public class Main {


    public static void main(String[] args) {
        ArrayList days = new ArrayList<>();

        days.add("Sun");
        days.add("Mon");
        days.add("Tue");
        days.add("Thu");
        days.add("Fri");
        days.add("Sat");

        ListIterator iterator = days.listIterator();

        while (iterator.hasNext()) {
            System.out.println(iterator.next());
        }

        iterator.set("None");

        System.out.println("After set : ");

        for (String item : days) {
            System.out.println(item);
        }
    }

}

Example 3: iterate a list using iterator

Iterator<String> crunchifyIterator = crunchifyList.iterator();
        while (crunchifyIterator.hasNext()) {
            System.out.println(crunchifyIterator.next());
        }
