I need help with this question coming from this book

9.1 (The Rectangle class) Following the example of the circle class in Section 9.2 o, 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 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.
