java - LinkedBlockingQueue 的插入和删除方法是线程安全的吗？

Question

我在两个不同的线程之间使用 LinkedBlockingQueue。一个线程通过add添加数据，而另一个线程通过take接收数据。

我的问题是，我是否需要同步访问 add 和 take。 LinkedBlockingQueue 的插入和删除方法是线程安全的吗？

Answer 1

是的。来自 the docs :

"BlockingQueue implementations are thread-safe. All queuing methods achieve their effects atomically using internal locks or other forms of concurrency control. However, the bulk Collection operations addAll, containsAll, retainAll and removeAll are not necessarily performed atomically unless specified otherwise in an implementation. So it is possible, for example, for addAll(c) to fail (throwing an exception) after adding only some of the elements in c."
