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 then implement the class. Write a test program that create two Rectangle objects - one with width 4 and height 40, and the other with width 3.5 and height 35.9.
Display the width, heigth, area, and perimeter of each rectangle in this order.
