LinkedList Iterator example

In this example we shall show you how to obtain a LinkedList Iterator. The Iterator is used to remove elements from an underlying Collection. To obtain a LinkedList Iterator one should perform the following steps:

  • Create a LinkedList.
  • Populate the list with elements, with add(E e) API method.
  • Obtain an Iterator, using iterator() method.
  • Iterate over the elements of the collection, with hasNext() and next() methods of Iterator,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;

import java.util.Iterator;
import java.util.LinkedList;
public class LinkedListIterator {
  public static void main(String[] args) {
    // Create a LinkedList and populate it with elements
    LinkedList linkedList = new LinkedList();
    // The Iterator object is obtained using iterator() method
    Iterator it = linkedList.iterator();
    // To iterate through the elements of the collection we can use hasNext() and next() methods of Iterator 
    System.out.println("LinkedList elements :");
