Java中是否有同步队列? [英] Is there a synchronized queue in Java?

问题描述

Java 中是否有同步的 Queue 类?我正在寻找类似 Vector(它是同步的)与 ArrayList(它不是)之类的东西，而不是实现 List 接口，我正在寻找它来实现 Queue.

Is there a synchronized Queue class in Java? I'm looking for something like Vector (which is synchronized) vs ArrayList (which is not), but instead of implementing the List interface, I'm looking for it to implement Queue.

请注意，没有 Collections.synchronizedQueue 方法可以包装未同步的队列并使其同步.

Note that there is no Collections.synchronizedQueue method to wrap an unsynchronized queue and make it synchronized.

推荐答案

查看 ArrayBlockingQueue 和另一个 BlockingQueue 实现.

Look at ArrayBlockingQueue and another BlockingQueue implementations.

来自文档:

额外支持在检索元素时等待队列变为非空以及在存储元素时等待队列中有可用空间的操作的队列.

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.
