Pictorial presentation of ArrayList.listIterator() Method

Example: Java ArrayList.listIterator Method

The following example creates an ArrayList with a capacity of 50 elements. Four elements are then added to the ArrayList and the ArrayList is trimmed accordingly.

import java.util.*;

public class test {
   public static void main(String[] args) {
      
    // create an empty array list 
    ArrayList<String> color_list = new ArrayList<String>();

    // use add() method to add values in the list
    color_list.add("White");
    color_list.add("Black");
	color_list.add("Red");
   
   System.out.println("List of the colors :" + color_list);
   
   // using listIterator() method get a ListIterator object
    ListIterator itrr = color_list.listIterator();
	   
   //Use hasNext() and next() methods to iterate through the elements in forward direction.
     System.out.println("Iterating in forward direction");
     while(itrr.hasNext())
      System.out.println(itrr.next());
 
 
   // Use hasPrevious() and previous() methods to iterate through the elements in backward direction.
      System.out.println("Iterating in backward direction");
	   
    while(itrr.hasPrevious())
      System.out.println(itrr.previous());
     }
}

Output:

F:\java>javac test.java

F:\java>java test
List of the colors :[White, Black, Red]
Iterating in forward direction
White
Black
Red
Iterating in backward direction
Red
Black
White
