Java Binary Semaphore (+Example) A binary semaphore is a synchronization primitive that can hold only two values, typically 0 and 1. We use binary semaphore to manage access to a shared resource by multiple threads in a concurrent environment. Conceptually, a binary semaphore can be thought of...

在多个线程中,各个线程共享同一地址空间和其他资源。在多个进程中,进程共享物理内存、磁盘、打印机和其他资源。因为线程会包含有一些进程的属性,所以线程被称为轻量的进程(lightweight processes)。多线程(multithreading)一词还用于描述在同一进程中多个线程的情况。
