Initializing a Queue in Java

Question

I have a class Queue that fully implements the Queue interface, however I have no idea on how to actually initialize the queue in my main Code.

Queue<T> q = ???

I have been searching the internet for the answer for 30+ minutes AND consulted the Java API docs, but I am outright stuck. I know this is a simple question, and because of that its driving me insane. Any help?

Queue is an interface. You can't instantiate an interface directly. Instead, choose an existing implementation. For example:

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

or

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

ArrayDeque is faster .
