synchronized class

Hello,

I would like to know whether the "synchronized class" construct is
valid in JDK 1.5 and whether it has any meaning at all in the context
of multithreaded programming or whether the compiler will ignore it
altogether. I have read some posts stating that "synchronized class"
is not a legal way to begin a Java class definitions. Any comments
on this would be sincerely appreciated.

Thanks,

JG
