Answer
It ensures changes to a variable are visible to all threads.
The 'volatile' keyword in Java ensures that changes to a variable are immediately visible to all threads. This prevents threads from using stale values in a multi-threaded environment. In a flash sale scenario, using 'volatile' for a flag that signals the end of a sale ensures that all threads promptly react to the sale's conclusion.
