This article mainly introduces the blocking queue container in Java thread programming, and introduces some basic methods for implementing blocking queues in JDK. For more information, see 1. What is a blocking queue? BlockingQueue is a queue that supports two additional operations. The two additional operations are a

returns NULL. When an element's Getdelay (Timeunit.nanoseconds) method returns a value less than or equal to zero, the expiration occurs, and poll removes the element. This queue does not allow the use of NULL elements. Here is the delay interface:Java codePublic interface Delayed extends comparableLong Getdelay (timeunit unit);}The elements put into delayqueue will also implement the CompareTo method, Delayqueue Use this to sort the elements.The fol

take an element out of the queue, and if not, return nullBlocking: When the blocked queue is full, if the producer threads put elements into the queue, the queue blocks the producer thread until it gets the data, or the response breaks out. When the queue is empty, the cons

to perform an add operation may result in a outofmemoryerror if the resource is exhausted, but if the queue is empty, then the operation take of the element is blocked, so its retrieval operation takes is blocked. In addition, the elements that go into the queue are more capable.Finally,Delayqueue(based on Priorityqueue) is an unbounded blocking queue that holds

baked, it is necessary to place the muffin in the Delayqueue for the recommended baking time. Listing 4, taken from the Delayqueueusageexample class, shows Enqueue and dequeue muffin objects from Delayqueue.As you can see, the baking time for the muffin object is set using its constructor (the constructor expects the baking time to be in seconds).As mentioned before, the Muffin object is not allowed to be taken out of the delayqueue until his delay time (also called baking time) is extended.

in Java multithreaded applications, queue usage is high, and the preferred data structure for most production consumption models is the queue. Java provides thread-safe queues that can be divided intoblocking queues and non-blocking queues, where the typical example of a blocking q
