Interfacepublic interface Queue extends Collection, Cloneable, Iterable, Serializable
Implementors CircularQueue, LinearQueue, LinkedList, TypedQueue

A collection designed for holding elements prior to processing. Besides basic Collection operations, queues provide additional insertion, extraction, and inspection operations.

Queues typically, but do not necessarily, order elements in a FIFO (first-in-first-out) manner.

Whatever the ordering used, the head of the queue is that element which would be removed by a call to remove() or poll().
