并发编程Java volatile关键字的相关内容

多线程与并发编程：解释什么是死锁，并给出一个在Java中发生死锁的例子。描述一下Java中的volatile关键字的作用，以及它与synchronized的区别。

死锁：死锁是指两个或多个线程在执行过程中，因争夺资源而造成的一种相互等待的现象。若无外力干涉，它们都将无法推进下去。这种情况通常发生在多个线程都占有部分共享资源但又都在等待其它线程释放自己需要的资源时。例如，在Java中，考虑以下场景： public class DeadlockExample {...

并发编程之 Java 内存模型 + volatile 关键字 + Happen-Before 规则

1. Java 内存模型到底是什么玩意？内存模型可以理解为在特定的操作协议下，对特定的内存或高速缓存进行读写访问的过程抽象。不同架构的CPU 有不同的内存模型。Java 作为跨平台语言，肯定要屏蔽不同CPU内存模型的差异，构造自己的内存模型，这就是Java 的内存模型。实际上，根源来自硬件的内存模型...
