About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The statement explains that using lock constructs ensures both that changes are seen by other threads and that operations happen indivisibly, whereas volatile only ensures visibility, not atomicity.
In simple terms: Locks give visibility and atomicity; volatile gives only visibility.
Key Takeaway
Use locks when you need both safety and visibility.
