AtomicReference类,其设计旨在实现对象引用的原子更新,这一功能在Java并发包中扮演关键角色。追溯其源头,AtomicReference于Java 5版本中首次出现,针对并发编程包java.util.concurrent.atomic的引入,旨在优化多线程环境下的线程安全操作。之前,Java主要依赖synchronized关键字和volatile关键字来确保线程安全和数据...
Here's an example of how you might use `AtomicReference` to perform thread-safe addition, albeit in a less efficient manner compared to using `AtomicInteger`: 以下是一个使用`AtomicReference`进行线程安全加法的示例,尽管与使用`AtomicInteger`相比效率较低: ```java import java.util.concurrent.atomic.At...

Methods declared in class java.lang.Object clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait Constructor Details AtomicReference public AtomicReference(V initialValue) Creates a new AtomicReference with the given initial value. Parameters: initialValue - the initial ...
这里包含高级的原子操作,例如compareAndSet()。AtomicBoolean位于Java.util.concurrent.atomic包中,因此全类名是java.util.concurrent.atomic.AtomicBoolean。这篇文章讲述的AtomicBoolean的版本可以在java 8中找到,第一个版本在java 5中增加。 AtomicBoolean设计背后的原理在我的另一篇文章Compare and Swap有解释。 创建Atomi...
首先volatile是java中关键字用于修饰变量,AtomicReference是并发包java.util.concurrent.atomic下的类。 首先volatile作用,当一个变量被定义为volatile之后,看做“程度较轻的 synchronized”,具备两个特性: 1.保证此变量对所有线程的可见性(当一条线程修改这个变量值时,新值其他线程立即得知) ...
