(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 data fields named width and height. - A constructor that creates a rectangle with the specified width and height. The default values are 1 and 2 for the width and height, respectively. - 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 objectsone with width 4 and height 40 and the other with width 3.5 and height 35.7. Display the width, height, area, and perimeter of each rectangle in this order.
