i have a class with 2 inner classes that are threads
how do i make this thread safe? make the check() method in Checker synchronized? put the o = c.check(); in a synchronized block using the monitor String object?

Hi Tom, I simplified your code as the stub you gave would never be able to compile : Please note that I don't like the idea that the inotification[/i] has to be in a synchronized block, but it's rather logical to have it so... So ! Please also note that this example s inspired from "JAVA threads" by Scott Oaks & Henry Wong at O'Reilly, ISBN 1-56592-216-6 Make sure you get the second edition at least, while these references dates to the first edition (ISBN number)
Originally posted by CL Gilbert: Tom, either of your proposed solutions would make that a thread safe operation.
Mhhh, you probably meant to write neither? It's not the check() that is critical, but parallel usage of o. This usage has to be synchronized.
