how an object is built?

[kevinn lee]

class G {
String s1 = "G.s1";
void printS1(){
System.out.print("G.printS1," + s1);
}
G() {
printS1();
}
}
class H extends G {
String s1 = "H.s1";
void printS1(){
System.out.print("H.printS1," + s1);
}
public static void main(String[] args) {
G h = new H();
}
}    

according to the output of the above code it seems that instance variables of the new object are not initialized but are declared at the time the super constructor is called.can someone explain the exact procedure of building an object stepwise?
whether an instance of the super class is built first and then its modified to a child object?at which step instance variables are declared and initialized etc?
thank you
