A Lock interface is one of the basic mechanisms provided by the Java concurrency API to synchronize a block of code. It allows you to define a critical section. A critical section is a block of code that accesses a shared resource and can't be executed by more than one thread at the same time. This mechanism is implemented by the Lock interface and the ReentrantLock class.
In this recipe, you will learn what information you can obtain about a Lock object and how to obtain that information.
