Question#1 (Constructors):
        1. Create a class called Rectangle that contains the following data fields:
        • height as integer.
        • width as integer.
        2. The class also contains the following methods:
        • A no-arguments constructor that initializes Rectangle data fields to their default values.
        • A two-arguments constructor that initializes Rectangle data fields to specific given values.
        • A method named getArea() that returns the area of the rectangle.
        3. In the main method:
