Java: The Volatile Keyword
Answer
Volatile is used for flags or state variables.
Volatile is ideal for variables used as flags or state indicators, where atomic operations are unnecessary. For instance, a volatile boolean 'shutdownRequested' can be checked by multiple threads to stop execution when set to true by any thread, ensuring all threads see the update immediately.
