synchronized keyword applied to - Static method vs. Non Static method ?

When a synchronized non static method is called a lock is obtained on the object.

When a synchronized static method is called a lock is obtained on the class and not on the object.

The lock on the object and the lock on the class don't interfere with each other.

It means, a thread accessing a synchronized non static method, then :

• The other thread can access the synchronized static method at the same time.

         AND

• Can't access the synchronized non static method.
