This example is a simple document management system. Like any formal document management system, we must provide concurrency management. That is, we need a method to solve the problem of two users trying to edit the same document. We will create some type of locking mechanism to prevent the edited documents from being

ThreadLocal in Java is another-achieve thread-safety apart from writing immutable classes. If you had been writing multi-threaded or concurrent code in Java then you must being familiar with cost of synchronization or locking which can greatly affect Scalability of application, but there was no choice other than synchronize if you are S Haring objects between multiple threads. ThreadLocal in Java is a different-achieve thread-safety, it doesn ' t address synchronization requirement, instead I T
