Using volatile keyword with mutable object

Question

In Java, I understand that volatile keyword provides visibility to variables. The question is, if a variable is a reference to a mutable object, does vola

Answer 1

Use of volatile rather than a fully synchronized value is essentially an optimization. The optimization comes from the weaker guarantees provided for a volatile value compared with a synchronized access. Premature optimmization is the root of all evil; in this case, the evil could be hard to track down because it would be in the form of race conditions and such like. So if you need to ask, you probably ought not to use it.
