At what stage of the interview is the use of a static synchronized method considered, and how is it used for access synchronization?

Using a static method with the synchronized modifier is usually discussed at the technical interview stage when assessing understanding of multithreading and synchronization in Java. This can be part of questions on Java fundamentals or during discussions of specific tasks related to thread safety.

A static synchronized method locks the class monitor, not the instance, which is important for synchronizing access to static resources.

Example:

public class Example {
    public static synchronized void staticSyncMethod() {
        // code synchronized at the class level
    }
}
