- Volatile variables can also be used to store shared variables at a lower cost than that of synchronization , but they have limitations
还可以使用可变变量来以比同步更低的成本存储共享变量，但它们有局限性。 - A shared variable or event is stored in memory only once , no matter how many or few instances you create of its class or structure
共享变量或事件只能在内存中存储一次，而无论您创建多少个它的类或结构的实例。 - Unfortunately , this situation is a common use case for volatile - using a volatile field as a " guard " to indicate that a set of shared variables had been initialized
