hai can anybody explain me why iam getting same output with the super.
 
the first statemet after call to super should be parent class constructor is it not.

class Parent
{
    int a = getA();
    
    {
        System.out.println("Parent Class Instance Initializer");
    }
    
    public Parent()
    {
        System.out.println("Parent Class Constructor");
    }
    
    private int getA()
    {
        System.out.println("Parent Class Member Initializer");
        return 0;
    }
}
 
public class Child extends Parent
{
    {
        System.out.println("Child Class Instance Initializer");
    }
    
    int b = getB();
    
    public Child()
    {
        System.out.println("Child Class Constructor");
    }
    
    private int getB()
    {
        System.out.println("Child Class Member Initializer");
        return 0;
    }
    
    public static void main(String[] args)
    {
        Child c = new Child();
        System.out.println("Done");
    }
}

A. Output is:
 
Child Class Constructor
Parent Class Constructor
Parent Class Member Initializer
Parent Class Instance Initializer
Child Class Member Initializer
Child Class Instance Initializer
Done
 
B. Output is:
 
Parent Class Member Initializer

Parent Class Constructor
Child Class Instance Initializer
Child Class Member Initializer
Child Class Constructor
Done
 
C. Output is:
 
Parent Class Member Initializer
Parent Class Instance Initializer

Child Class Member Initializer
Child Class Instance Initializer
Child Class Constructor
Done
 
D. Output is:

Child Class Member Initializer
Done
class Parent
{
    int a = getA();
    
    {
        System.out.println("Parent Class Instance Initializer");
    }
    
    public Parent()
    {
        System.out.println("Parent Class Constructor");
    }
    
    private int getA()
    {
        System.out.println("Parent Class Member Initializer");
        return 0;
    }
}
 
public class Child extends Parent
{
    {
        System.out.println("Child Class Instance Initializer");
    }
    
    int b = getB();
    
    public Child()
    {
        System.out.println("Child Class Constructor");
    }
    
    private int getB()
    {
        System.out.println("Child Class Member Initializer");
        return 0;
    }
    
    public static void main(String[] args)
    {
        Child c = new Child();
        System.out.println("Done");
    }
}
