Is Constructor Overriding Possible?

Question

What i know is, the compiler writes a default no argument constructor in the byte code. But if we write it ourselves, that constructor is called automatically. Is this pheno

Answer 1

No it is not possible to override a constructor. If we try to do this then compiler error will come. And it is never possible in Java. Lets see the example. It will ask please write a return type o the method. means it will treat that overriden constructor as a method not as a constructor.

package com.sample.test;

class Animal{

    public static void showMessage()
    {
        System.out.println("we are in Animal class");
    }
}

class Dog extends Animal{

    public void DogShow() 
    {
        System.out.println("we are in Dog show class");
    } 

    public static void showMessage()
    {
        System.out.println("we are in overriddn method of dog class");
    }
}

public class AnimalTest { 

    public static void main(String [] args)
    {
        Animal animal = new Animal();
        animal.showMessage();

        Dog dog = new Dog();
        dog.DogShow();

        Animal animal2 = new Dog();
        animal2.showMessage();
    }

}
