Java: Synchronized and Locks
Answer
It locks the class' intrinsic lock. Frame the concept in practical terms so you can explain it during interview discussion.
Synchronizing a static method uses the class's intrinsic lock (Class object) rather than an instance lock. This ensures that only one thread can execute any synchronized static method of a class at a time, regardless of which object instance is calling it. This can be crucial when managing shared class-level resources, like a static inventory counter in a flash sale.
