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 ...

In Java, there’s a logical connection between the monitor and every object or class. Hence, they cover instance and also static methods. Mutual exclusion is accomplished with a lock associated with every object and class. This lock is a binary semaphore called amutex. ...
