“Mutex is typically used to serialize access to a section ofre-entrant codethatcannot be executed concurrentlyby more than one thread. A mutex object only allows one thread into a controlled section, forcing other threads which attempt to gain access to that section to wait until thefirst t...
Mutex and Semaphore in Java both used to provide mutual exclusion for critical section of code but they are completely different to each other. If you want a block of code can be only executed by one thread at a given time you usually lock that portion of code using a mutext which is ...

最后一种说法听起来不常见,但却是关键。Shared mutexes are ruled out trivially, because as soon as one thread obtains the mutex, your worst enemy could simply never schedule that thread again。当然,真正的操作系统的工作方式没那么简单,这只是定义术语的比方。 下面是一个简单的示例,它不包含互斥锁,但仍...

重点:ReentrantLock底层实现依赖于特殊的CPU指令,比如发送lock指令和unlock指令,不需要用户态和内核态的切换,所以效率高(这里和volatile底层原理类似),而synchronized底层由监视器锁(monitor)是依赖于底层的操作系统的Mutex Lock需要用户态和内核态的切换,所以效率低。
2. What is mutex? Mutex is a way of mutual exclusion referring to the problems of ensuring that no two processes or threads can be in their critical section at same time. Here, a critical section refers to a period of time when process accesses a shared resource, such as shared memory....
