There is no point in showing what they do here. Of course the same options for offer, poll and peek are available, however they do not work with exceptions but rather with special values. Removes the first item at the tail of the queue Removes the first item at the head of the queue Gets the first item of the tail of the queue without removing it. Gets the first item of the head of the queue without removing it. The additional methods really speak for them self if you know how a queue works, since those methods are intended to add more flexibility: Method The Deque inherits the Queue interface which means the regular methods remain, however the Deque interface offers additional methods to be more flexible with a queue. The queue only can add elements to the tail of a queue. # Deque莫 Deque is a "double ended queue" which means that a elements can be added at the front or the tail of the queue. A bounded BlockingQueue is one which is initialized with initial capacity.莫nd the thread will be blocked after the second output. Operation莫 BlockingQueue can be bounded or unbounded. #JAVA QUEUE FULL#A thread trying to enqueue an item in a full queue is blocked until some other thread makes space in the queue, either by dequeuing one or more items or clearing the queue completely.墨lockingQueue methods come in four forms, with different ways of handling operations that cannot be satisfied immediately, but may be satisfied at some point in the future: one throws an exception, the second returns a special value (either null or false, depending on the operation), the third blocks the current thread indefinitely until the operation can succeed, and the fourth blocks for only a given maximum time limit before giving up. A thread trying to dequeue from an empty queue is blocked until some other thread inserts an item into the queue. Stack : 10 was popped from the stack莫 BlockingQueue is an interface, which is a queue that blocks when you try to dequeue from it and the queue is empty, or if you try to enqueue items to it and the queue is already full. In the while loop below, the elements are removed from the Queue based on FIFO. This insertion operation is called enqueue. In the example below, with offer() method, the elements are inserted into the LinkedList. The class, while implementing is a general-purpose implementation of interface too operating on a FIFO (First In, First Out) (opens new window) principle. println ( queue ) //The Output: # LinkedList as a FIFO Queue asList ( 9, 2, 3, 1, 3, 8 ) ) //The PriorityQueue sorts the elements by using compareTo method of the Integer Class //The head of this queue is the least element with respect to the specified ordering System. PriorityQueue queue = new PriorityQueue ( ) //The elements are added to the PriorityQueue The type of the PriorityQueue is Integer.
