I need help with a Java exercise. I am in Introduction to Programming using Java by Daniel Liang so it is known what example this is talking about. Hopefully that helps. Please make this as basic and simple as possible. Thank you.

Problem 1: 9.1 (The Rectangle Class) pg. 360 in the textbook

Following the example of the Circle class in Section 9.2, 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 (using Word or some other editor) 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 35.9. Display the width, height, area, and perimeter of each rectangle in this order.
