NO....
it's very bad design, if you are calling constructor of super class from sub class.
child is calling parent class method, so child has to use super().

But according to me if we dont write the super() in Sub Class then also by default it is used in the first line of the subclass constructors.

If the super() is not written in the subclasses then no constructors of super classes is loaded in memory and then we cannot create an instance of the subclasses.

Tell me if this concept is right

yes we can call by simpy Intilizing the Object of the sub class. Intrernally the default contrutor will call the super class . if there is no construtor declerd with parameter.

if any contrutor declared with parameter the we need to call super class construtor explicetly ,bypassing paremater . It should be the first line of the sub class construtor

it's happened by default. if we create the object of subclass the it will implicitly or accordingly call the super class constructor.

class A{
   A(){}
}
class B extends A{
   B(){}
}

public class C {
   public static void main(Strinng args[]){
      B obj = new B();
}
}

in the above code , when obj is created constructor of A is called automatically.
