11. Show what is written by the following segment of code, given that item1, item2, and item3 are integer variables, and queue is an object that fits our abstract description of a queue. Assume that you can store and retrieve variables of type int on queue. item1 = 1 ; item23 item3 = 4; queue.enqueue (item2) ; queue.enqueue (iteml) queue.enqueue (iteml + item3) item3 = queue. dequeue ( ) ; queue.enqueue (item3*item3): queue.enqueue (item2) queue.enqueue (7) item2 = queue . dequeue ( ) ; System.out.println (iteml+"" + item2 item3) while (!queue.isEmpty)) item! = queue.dequeue() ; System.out.print (item1 + ",)
