Define a class of rectangles. Please name your test program as "RectangleTest"

How to hand in the assignment

Follow the steps below:

Complete the UML in a Microsoft Word document or other document file format,

and the programs in $.$java files. Once you are done, convert your UML file to a

PDF $(.$pdf$).$

Upload the $.$java files as well as the PDF document UML into Gradescope. Do

not submit a $.$docx file for the UML, first convert your file to PDF $(.$pdf$).$

Click "Upload".

I remind you that if you do not submit the assignment before the due date, you will not be

able to submit it$.$

Note: Your output should look exactly like the output below and should be able to

run test cases.

The area is

The perimeter is

Design a class named Rectangle. The class contains:height of the rectangle. The default values are $1\mathrm{.}0$ for both width and height.

$>$ A no$-$arg constructor that creates a default rectangle.

$>$ A constructor that creates a rectangle with a specified width and height.

$>$ Two sets of get and set methods for the two private data fields.

$>$ A method named getArea$()$ that returns the area of a rectangle.

$>$ A method named getPerimeter$()$ that returns the perimeter.

Please make sure to follow this sequence of steps:

Draw the UML of the Rectangle class. The data fields should be private, and

constructors and all other methods should be public.

Implement the Rectangle class $($name it "Rectangle"$)$ in Rectangle.java.

Implement the RectangleTest class $($name it "RectangleTest"$)$ with the main

method in RectangleTest.java. It should do the following tasks:

Create a rectangle object with width $4\mathrm{.}0$ and height $40\mathrm{.}0.$

Change the rectangle's width to $5\mathrm{.}0$ and height to $50\mathrm{.}0.$

Print out the area of the rectangle.

Print out the perimeter of the rectangle.

Grading: This lab is worth $100$ points. Out of $100$ maximum points, the UML will

count for $20$ points, the two source codes will count for $80$ points.
