static synchronized methods and non-static synchronized method

Q Can two threads call two different static synchronized methods of the same class?

Ans) No. The static synchronized methods of the same class always block each other as only one lock per class exists. So no two static synchronized methods can execute at the same time.

Q Does a static synchronized method block a non-static synchronized method?

Ans)No As the thread executing the static synchronized method holds a lock on the class and the thread executing the non-satic synchronized method holds the lock on the object on which the method has been called, these two locks are different and these threads do not block each other.
