Well, I think I have to put static keyword to specify my method. If not,
different instances will be created and synchronize won't protect all the
instances. Am I understand it correct?
Thanks.

It's my understanding that the synchronize keyword does exactly as the name
implies... it synchronizes usage of that method, so that other threads
wishing to use the method have to wait until the thread currently using it
is finished.
