Volatile vs Static in Java

Question

Is it correct to say that static means one copy of the value for all objects and volatile means one copy of the value for all threads?

Anyway a static variable value is also going to be one value for all threads, then why should we go for volatile?

Answer 1

I think static and volatile have no relation at all. I suggest you read java tutorial to understand Atomic Access, and why use atomic access, understand what is interleaved, you will find answer.
