Program: How to read all elements in LinkedList by using iterator?

Here we can see example for reading all elements from LinkedList by using Iterator. Also you can iterate through the LinkedList based on index too.

package com.java2novice.linkedlist;

import java.util.Iterator;
import java.util.LinkedList;

public class MyLinkedListIterate {

	public static void main(String a[]){
		LinkedList<String> arrl = new LinkedList<String>();
		//adding elements to the end
		arrl.add("First");
		arrl.add("Second");
		arrl.add("Third");
		arrl.add("Random");
		Iterator<String> itr = arrl.iterator();
		while(itr.hasNext()){
			System.out.println(itr.next());
		}
	}
}

First
Second
Third
Random
