When a class is loaded, the JVM calls a method in the class called <clinit>()V This method sets all initial values and in your case, it sets the static field.

It can create instances while the method is being called, but it does mean you can't assume in a constructor that all the static fields have been set if you do this.

There's nothing strange here. The class is loaded, then new A() is created and assigned to objA. How it actually happens internally is not really relevant, and may vary between JVMs.
