Java: The Volatile Keyword
Answer
Volatile does not guarantee atomicity. Frame the concept in practical terms so you can explain it during interview discussion.
While 'volatile' ensures the visibility of changes to a variable across threads, it doesn't guarantee that operations on the variable are atomic. For example, a statement like `counter++` involves reading, modifying, and writing, which are not atomic operations. In such cases, additional synchronization is required to ensure thread safety.
