o exercise 9.1 in the book (page 362, or page 384 of the Comprehensive Version of the book) Also add a method named getDiagonal which computes and returns the diagonal of the rectangle. For example the distance from the top left corner to the bottom right corner. Or equivalently the distance from the top right corner to the bottom left corner. Call this method and display it's output in your test program. for the two Rectangle objects. Here is exercise 9.1 from the book: (The Rectangle class) Following the example of the Circle class in Section 9.2, design a class named Rectangle to represent a rectangle. The class contains: - Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. - A no-arg 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. - A method named getPerimeter() that returns the perimeter. Write a test program that creates two Rectangle objects—one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.

(The Rectangle class) Following the example of the Circle class in Section 9.2,
design a class named Rectangle to represent a rectangle. The class contains:
- Two double data fields named width and height that specify the width and
height of the rectangle. The default values are 1 for both width and height.
- A no-arg 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.
- A method named getPerimeter() that returns the perimeter.
Write a test program that creates two Rectangle objects—one with width 4 and height 40, and the other with width 3.5 and height 35.9.
Display the width, height, area, and perimeter of each rectangle in this order.
