7.1 Following the example of the Circle class in Section7.2, design a class named Rectangle to represent a rectangle. The classcontains: 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 testprogram 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.
