When a thread accesses a static synchronized method of a class, then it acquires the class lock i.e., Test.class lock instead of Test's instance lock.

It will be better understood by this code....



Here you will get only one output. either main or child.

class specific locks can be acquired by
1.synchronizing on static methods.
2.synchronizing on the static objects defined in the class.
3.Locking on external objects like System.out
4.Locking on Singleton Objects.
