Question

What is mutex and semaphore in Java ? What is the main difference ?

Answer 1

You compare the incomparable, technically there is no difference between a Semaphore and mutex it doesn't make sense. Mutex is just a significant name like any name in your application logic, it means that you initialize a semaphore at "1", it's used generally to protect a resource or a protected variable to ensure the mutual exclusion.
