The long and double assignments in Java are not atomic operations, since 32 bits are written, and then 32 bits are written, in two steps, so the thread is unsafe. If you change to the following, it's thread safe.Private volatile long number = 8;So, why is that so? Can the volatile keyword guarantee atomicity?Java programmers are familiar with the phrase: volatile is only used to ensure that the variable for all threads of visibility, but not guarantee

The creation of objects in the Java command is separated from the value assignment operation, that is, instance = new Singleton () is divided into two steps. However, the JVM does not guarantee the order of the two operations. That is to say, the JVM may allo

threadlocal when writing multithreaded code.of course, threadlocal can not replace the synchronization mechanism, the problem areas are different. The synchronization mechanism is to synchronize multiple threads for concurrent access to the same resource, which is an efficient way to communicate between multiple threads, while threadlocal is a data share that isolates multiple threads, and essentially does not share resources (variables) across multiple threads, which of course does not require
