class A{
static void synchronized void call() {
}
synchronized void call(){}
}

One lock will be needed for the class and also a lock is needed for the instance when invoking call().

Are they independent of each other or mutually exclusive?

They are independent locks. By the way your code will not compile for two reasons. Can you see them?
