How to Iterate Over Elements of Java LinkedList

In this example we will show how to iterate over elements of Java LinkedList using ListIterator’s next, hasNext, hasPrevious and previous methods.

Source Code

package com.beginner.examples;

import java.util.LinkedList;
import java.util.ListIterator;

public class IterateLinkedListUsingListIterator {

	public static void main(String[] args) {
		
		//create LinkedList.
		LinkedList linkedList = new LinkedList();
		
		linkedList.add("A");
		linkedList.add("B");
		linkedList.add("C");
		linkedList.add("D");
		
		/*
		 * To get an ListIterator object of LinkedList, use
                 * ListIterator listIterator() method.
		 */
		ListIterator itr = linkedList.listIterator();
		
		while(itr.hasNext()) {
			System.out.println(itr.next());
		}
	}
}

Output:

A
B
C
D
