Can I create any object of ArrayList in a Queue?

I am trying to do this:

Queue<Integer> Q = new ArrayList<Integer>();

But My IDE gives me error.

Can any one please tell me, Why I can't create an object of ArrayList in a class of queue?

Using of ArrayDeque instead of LinkedList makes it a little bit faster ...

Queue<Integer> q = new ArrayDeque<>();

You can't do that because ArrayList does not implement Queue. You could use a LinkedList instead:

Queue<Integer> q = new LinkedList<>();
