Write out the order of elements that are contained in a queue after the following operations are performed.

What will be an ideal response?
```
myQueue.enqueue(new Integer(8));
myQueue.enqueue(new Integer(6));
Integer num1 = myQueue.dequeue();
myQueue.enqueue(new Integer(3));
myQueue.enqueue(new Integer(4));
myQueue.enqueue(new Integer(15));
myQueue.enqueue(new Integer(12));
myQueue.enqueue(new Integer(9));
myQueue.dequeue();
myQueue.dequeue();
myQueue.dequeue();
myQueue.enqueue(new Integer(19));
```

The resulting queue from front to back is 15,12,9,19.
