Accessing each element in ArrayDeque

Question

Is it possible to access the element stored in ArrayDeque in each iteration ? Since ArrayDeque doesn't have the get method, its difficult for me to access each element. In the following example I have an integer arraydeque and i'm trying to retrieve the elements using an iterator and i want to check if the value is 2. If so i want to remove it from the ArrayDeque, but it gives me error.

import java.lang.*;
import java.util.*;

public class ArrayDequeTest {

public static void main(String[] args) 
{   
    ArrayDeque<Integer> a = new ArrayDeque<Integer>();
    a.add(1);
    a.add(2);
    a.add(3);
    a.add(4);
    a.add(2);
    System.out.println("Elements added !!");

    Iterator i = a.iterator();
    System.out.println("\nRemoving the element whose value is 2");
    while(i.hasNext())
    {
        if(i==2) // please suggest as to how i can compare
        {
            i.remove();
        }
    }
}

If you're using Java 8, you can make use of lambda expression and can get this removal operation done in just one line.

 a.removeIf(e -> e == 2);
