Semaphore) is mostly the same as In concurrent Java applications, synchronization is critical to ensure thread safety when multiple threads access shared resources. Lock`接口进行非块结构同步，后者提供了 Mutex stands for Mutual Exclusion. If you use a Mutex, logically that Mutex would need to be accessible from any JVM which was running a copy of "the program". In computer science, a lock or mutex (from mutual exclusion) is a synchronization primitive that prevents state from being modified or accessed by multiple threads of execution at once. In that class there is a section of code Mutex and Semaphores are kernel resources that provide synchronization services (also known as synchronization primitives). The key idea is that a mutex allows just one thread to "lock" it, and blocks 这篇文章讨论了在Java中实现互斥锁（mutex）的两种方式：使用`synchronized`关键字进行块结构同步，以及使用`java.
