Answer / michael selvan
Class Lock - If a static method is marked as Synchrnozied
and called by a Thread, the whole Class will be locked
until the method execution completed.
Note : If we declare as a any static variables or methods
those will be stored in class area. So, if the method is
synchronized static . It'll lock the complete class.
