Java – LinkedList Iterator example

In the last post we learnt how to traverse a LinkedList using ListIterator. Here we will learn how to iterate a LinkedList using Iterator.

Example

The steps we followed in the below program are:

1) Create a LinkedList
2) Add element to it using add(Element E) method
3) Obtain the iterator by calling iterator() method
4) Traverse the list using hasNext() and next() method of Iterator class.

import java.util.LinkedList;
import java.util.Iterator;
public class IteratorExample {
 
 public static void main(String[] args) {
 
    // Create a LinkedList
    LinkedList<String> linkedlist = new LinkedList<String>();
 
    // Add elements to LinkedList
    linkedlist.add("Delhi");
    linkedlist.add("Agra");
    linkedlist.add("Mysore");
    linkedlist.add("Chennai");
    linkedlist.add("Pune");
 
    // Obtaining Iterator
    Iterator it = linkedlist.iterator();
 
    // Iterating the list in forward direction
    System.out.println("LinkedList elements:");
    while(it.hasNext()){
       System.out.println(it.next());
    }
 }
}

Output:

LinkedList elements:
Delhi
Agra
Mysore
Chennai
Pune
