In this Java tutorial, we are going to discuss the circular queue and its array implementation in java. What is Circular Queue? Circular Queue is a linear data structure in which operations are performed on FIFO
The above figure shows the queue of numbers. Since, we didn’t perform any deletion in the queue. Therefore, the value of front will remain -1. However the value of rear increases by 1 every time whenever the insertion operation is performed in the queue. C++ Java Python #include <bits/...
In this article, we will understand the Java concurrent queue, BlockingQueue. We will then go deep into it’s one of the implementation, ArrayBlockingQueue.

Simple Queue:In Simple queue, insertion of the element takes place at the rear end i.e. ENQUEUE and removal of the element takes place at the front end i.e. DEQUEUE. Simple queue is also called a linear queue. Circular Queue:In a circular queue, the elements act like a circular ring....
根据编程语言的不同,数组存在一些差异。对于 JavaScript 和 Ruby 等动态语言而言,数组可以包含不同的数据类型:数字,字符串,对象甚至函数。而在Java、 C 、C ++ 之类的强类型语言中,你必须在使用数组之前,定好它的长度与数据类型。JavaScript 会在需要时自动增加数组的长度。

ArrayBlockingQueue的类图如下: 其定义如下: publicclassArrayBlockingQueue<E>extendsAbstractQueue<E>implementsBlockingQueue<E>, java.io.Serializable {/** Much of the implementation mechanics, especially the unusual * nested loops, are shared and co-maintained with ArrayDeque.*//*** Serialization ID. ...
Queue Implementation MethodsWe'll implement following methods to implement queue.enqueue− inserts an element to the queue. dequeue− deletes an element from the queue. front− get the first element of the queue.Let's create a Queue class in following steps:...
Java ArrayBlockingQueue example. ArrayBlockingQueue is concurrent and bounded blocking queue implementation backed by an array. It orders elements in FIFO.
In some cases, a programmer may even choose to change from an array to a function-based implementation of a mapping, or vice versa (Exercise 7.10). Declarations Example 7.48 Array Declarations In some languages one declares an array by appending subscript notation to the syntax that would be ...
