The above link doesn't meet my requirement...

Then you need to read it more closely. Static initializers are executed before anything else when the class is first constructed.

hello Richard actually both cases will initialize before class construction...
I need some more internal concept.

if you put in static block System.out.println(A.y); then also it will not produce any error. what actually happens internally....
