Answer / jamshed katta
A lock can be acquired on a class, you would want to do that if you are using static methods in your class, in which case there would be only one copy, so you would need a lock on the class rather than the instance.
Eg:
public static int getPageHits{ // Not synchronized
return hits;
}
so, now instead of using
public static int getPageHits{
synchronized(this){
return hits;
}
}
you would rather do
public static int getPageHits{
synchronized(ClassName.class){
return hits;
}
}
where ClassName is the name of the class whose lock u are trying to acquire.
you could also use Class.forName("ClassName")
