Acquires the lock if it is not held by another thread and returns immediately with the value true, setting the lock hold count to one. Even when this lock has been set to use a fair ordering policy, a call to tryLock() will immediately acquire the lock if it is available, whether or not other threads are currently waiting for the lock. This.
What is Lock(), UnLock(), ReentrantLock(), TryLock() and How it's different from Synchronized

In this Java concurrency tutorial, you will understand how ReadWriteLock works and use it for simple cases with ReentrantReadWriteLock implementation.. Basically, a ReadWriteLock is designed as a high-level locking mechanism that allows you to add thread-safety feature to a data structure while increasing throughput by allowing multiple threads to read the data concurrently and one thread to.
