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

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

package com.java2novice.arraylist;

import java.util.ArrayList;
import java.util.Iterator;

public class ArrayListIterator {

	public static void main(String a[]){
		ArrayList<String> arrl = new ArrayList<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
