Answer 1

Just_ Luvvv behind the scenes the b class looks like this the moment you create an object, super class constructor is called first as B cannot exist without A being constructed first

class B extends A {
public B(){
super(); // but you dont see this
System.out.println(" Csnstrctr B");
}
}

Answer 2

you are better off not calling super in the child class since you are not call the superclass' contructor.Again you are extending A in program hence program has access to all methods defined in A thus just calling alpha would be better.
