Java vs. C#

Initialization of Parent Constructor

Java
 
//super constructor called before the subclass's

public class ParentClass
{
    public ParentClass()
    {
        System.out.println("Parent Constructor.");
    }

    public void print()
    {
        System.out.println("I'm a Parent Class.");
    }
}

public class ChildClass extends ParentClass
{
    public ChildClass()
    {
        System.out.println("Child Constructor.");
    }

    public static void main(String[] args)
    {
        ChildClass child = new ChildClass();
        child.print();
    }
}

Output:
    Parent Constructor.
    Child Constructor.
    I'm a Parent Class.


public class Parent
{
    String parentString;
    public Parent()
    {
        System.out.println("Parent Constructor.");
    }

    public Parent(String myString)
    {
        parentString = myString;
        System.out.println(parentString);
    }

    public void print()
    {
       System.out.println("I'm a Parent Class.");
    }
} 

public class Child extends Parent
{
    public Child() {
        super("From Derived");
        System.out.println("Child Constructor.");
    }

    public void print()
    {
       super.print();
       System.out.println("I'm a Child Class.");
    }

    public static void main(String[] args)
    {
        Child child = new Child();
        child.print();
        ((Parent)child).print();
    }
}
Output:
    From Derived
    Child Constructor.
    I'm a Parent Class.
    I'm a Child Class.
    I'm a Parent Class.
    I'm a Child Class.

C#

    {
        ChildClass child = new ChildClass();

        child.print();
    }
}
Output:
