(The Rectangle class ) Following the example of the Circle class in Section 8.2, 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. Draw the UML diagram for the class and then implement the class . 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.
