«volatile» is a keyword used when a variable can be used by many threads. It allows an asynchronous access to this variable. By using this keyword the JVM refreshes, after each use, the value of this variable, the value is updated and every thread gets the most recent value. That can be useful when we manage a workflow process for example.
