Why default constructor is required in a parent class if it has an argument-ed constructor?

Question

Why default constructor is required(explicitly) in a parent class if it has an argumented constructor

class A {    
  A(int i){    
  }
}

class B extends

I would guess that its because when you have an empty parameter list the super variable can't be instantiated. With empty parameter list I mean the implicit super() the compiler could add if the super class had a nonparametric constructor.

For example if you type:

int a;
System.out.print(a);

You will get an error with what I think is the same logic error.
