We cant run directly the parent class constructor in child class if the child class defines a constructor. Inheritance enables you to define a base class (also called parent class) and create one or more classes derived from it. We will face two cases while calling the parent constructor method in child class. Inheritage is a characteristic of the classes that lets you to transfer /use properties, constants and methods from one class to another, in an hierarchical structure. So whenever we use super keyword inside a child constructor then it calls the default parent constructor by itself.

But for print method it does not give any compile time error and consider it a overriding method. If we define Parent class constructor inside Child class it will give compile time error for return type and consider it a method.
