Mutex

Mutex is the simplest type of synchronizer.Mutex is the short of Mutual Exclusion. Mutex is a synchronization mechanism used in concurrent programming to prevent multiple threads from simultaneously accessing a shared resource or critical section of code that cannot be executed concurrently. The primary purpose of a mutex is to ensure that only one thread at a time can perform a specific operation or access a shared resource, thereby preventing data races and ensuring thread safety.

Where to use

• To avoid race condition
• They are often used for mutual exclusion, where only one thread can access a resource at a time.

How to implment mutex

• Using synchronized keyword (Provides intrinsic lock)
• Using ReentrantLock (Explicit locking)
• Using semaphore (setting permit count as 1)
