Volatile - synchronized ?

[kri shan]

Can i specify volatile variable within synchronized method or synchronized block ? Volatile works only with multithreaded code(non thread-safe) ?

[Sebastian Janisch]

volatile is a modifier that only applies for instance and class variables.

It makes that different Threads do not cache the value of the corresponding variable and hence always retrieve the latest, up-to-date, could-have-been-modified-by-another-thread value.

If you are interested in understanding Synchronization and about volatile modifier and if you have time, consider reading Synchronization and Java Memory Model.

[Campbell Ritchie]

Probably best moved to the threads forum.

One thing to note, there is only one non access modifier for local variables and that is final. There are no other non access modifiers for local variables.
