![]() Using yLock(long timeout, TimeUnit timeUnit), it is possible.Ģ) The synchronized block must be fully contained within a single method. The main differences between a Lock and a synchronized block are:ġ) Having a timeout trying to get access to a synchronized block is not possible. Difference between Lock Interface and synchronized keyword Finally unlock() is called, and the Lock is now unlocked so other threads can lock it. Any other thread calling lock() will be blocked until the thread that locked the lock calls unlock(). Here is the simple use of Lock interface.įirst a Lock is created. ReentrantLock is one such implementation of Lock interface. Since Lock is an interface, you need to use one of its implementations to use a Lock in your applications. A Lock is, however, more flexible and more sophisticated than a synchronized block. Lock InterfaceĪ .Lock is a thread synchronization mechanism just like synchronized blocks. In this tutorial, we will see a basic usage of Lock interface to solve printer queue problem. ![]() Java provides another mechanism for the synchronization of blocks of code based on the Lock interface and classes that implement it (such as ReentrantLock). We are already aware of basic concepts around thread synchronization and various mechanisms using synchronized keyword.
