Design a class named Rectangle to represent a rectangle. The class contains:

• Two integer data fields named width and height that specify the width and height of the rectangle. The default values are 1 (one) for both width and height.

• A constructor that creates a default rectangle.

• A constructor that creates a rectangle with the specified width and height.

• A method named getArea() that returns the area of this rectangle.
