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 ...
Mutex:Is a key to a toilet. One person can have the key - occupy the toilet - at the time. When finished, the person gives (frees) the key to the next person in the queue.Semaphore:Is the number of free identical toilet keys. Example, say we have four toilets with identical locks...

One main reason that recursive mutexes are useful is in case of accessing the methods multiple times by the same thread. For example, say if mutex lock is protecting a bank A/c to withdraw, then if there is a fee also associated with that withdrawal, then the same mutex has to be used...

I'm new to Computer Science and I'm reading a book which introduces threads and mutexes. I've tried programming a mutex in Java which seems to work most of the time but every so often it won't. In my code, the critical section adds on the numbers 1 to 10 to a static variable j...
Java multi threads example to show you how to use Semaphore and Mutex to limit the number of threads to access resources. Semaphores – Restrict the number of threads that can access a resource. Example, limit max 10 connections to access a file simultaneously. Mutex – Only one thread to ...
