Why do this() and super() have to be the first statement in a constructor?

Question

Java requires that if you call this() or super() in a constructor, it must be the first statement. Why?

For example:

public class MyClass {
    publi         


        

Answer 1

The main goal of adding the super() in the sub-class constructors is that the main job of the compiler is to make a direct or indirect connection of all the classes with the Object class that's why the compiler checks if we have provided the super(parameterized) then compiler doesn't take any responsibility. so that all the instance member gets initialized from Object to the sub - classes.
