Uses of Interface
java.util.Queue

Packages that use Queue
java.util	Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
java.util.concurrent	Utility classes commonly useful in concurrent programming.

Uses of Queue in java.util

Subinterfaces of Queue in java.util
`interface`	`Deque<E>` A linear collection that supports element insertion and removal at both ends.

Classes in java.util that implement Queue
`class`	`AbstractQueue<E>` This class provides skeletal implementations of some `Queue` operations.
`class`	`ArrayDeque<E>` Resizable-array implementation of the `Deque` interface.
`class`	`LinkedList<E>` Linked list implementation of the `List` interface.
`class`	`PriorityQueue<E>` An unbounded priority queue based on a priority heap.

Methods in java.util that return Queue

static



<T> Queue<T>

Collections.asLifoQueue(Deque<T> deque)
Returns a view of a Deque as a Last-in-first-out (Lifo) Queue.

Uses of Queue in java.util.concurrent

Subinterfaces of Queue in java.util.concurrent
`interface`	`BlockingDeque<E>` A `Deque` that additionally supports blocking operations that wait for the deque to become non-empty when retrieving an element, and wait for space to become available in the deque when storing an element.
`interface`	`BlockingQueue<E>` A `Queue` that additionally supports operations that wait for the queue to become non-empty when retrieving an element, and wait for space to become available in the queue when storing an element.

Classes in java.util.concurrent that implement Queue
`class`	`ArrayBlockingQueue<E>` A bounded blocking queue backed by an array.
`class`	`ConcurrentLinkedQueue<E>` An unbounded thread-safe queue based on linked nodes.
`class`	`DelayQueue<E extends Delayed>` An unbounded blocking queue of `Delayed` elements, in which an element can only be taken when its delay has expired.
`class`	`LinkedBlockingDeque<E>` An optionally-bounded blocking deque based on linked nodes.
`class`	`LinkedBlockingQueue<E>` An optionally-bounded blocking queue based on linked nodes.
`class`	`PriorityBlockingQueue<E>` An unbounded blocking queue that uses the same ordering rules as class `PriorityQueue` and supplies blocking retrieval operations.
`class`	`SynchronousQueue<E>` A blocking queue in which each insert operation must wait for a corresponding remove operation by another thread, and vice versa.
