What is the role of `volatile` in ensuring thread safety in Java?
`volatile` ensures that threads use the same copy of a variable, but it does not provide synchronization, so it canâ€™t ensure atomicity of operations on the variable.
Thatâ€™s partially correct. `volatile` guarantees visibility but does not guarantee atomicity. For atomicity, other synchronization mechanisms like `synchronized` are required.
Can you explain the differences between `volatile` and `synchronized` in terms of thread safety?
