It is used to update integer value atomically.Īn int array in which elements may be updated atomically.Ī reflection-based utility that enables atomic updates to designated volatile int fields of designated classes. It is used to update boolean value atomically. The package provides the following atomic classes: Class The method works the same as read and writes on volatile variables. All the atomic classes have the get() and set() methods that work on the volatile variable. The atomic classes provide a lock-free and thread-safe environment or programming on a single variable. Java provides a package in which atomic classes are defined. In this section, we will discuss atomic classes, atomic variables, atomic operations, along with examples.īefore moving ahead in this section, ensure that you are aware of thread, synchronization, and lock in Java. In such cases, the atomic variable can be a solution to it. So, it is important to take care of the shared entity while accessing concurrently. Hence, they may lead to inconsistency of the program.
The shared entity such as objects and variables may be changed during the execution of the program. The multi-threading environment leads to a problem when concurrency is unified.
In Java, atomic variables and operations used in concurrency.
