Design a public class named Rectangle to represent a rectangle following the example of the Circle class we did in Lesson #5.

The Rectangle class contains:

Data fields:

o private double data field width with default value 2

o private double data field length with default value 3

Two constructor methods:

o A no-argument constructor that creates a default rectangle with the default values

o A constructor that creates a rectangle with the specified width and length in the formal parameters

Instance methods:

o A public method named getPerimeter() that returns the perimeter of the rectangle (double)

o A public method named getArea() that returns the area of the rectangle (double)

o Public getter methods to access the data fields, specifically:

getWidth()

getLength()

o Public setter methods to set the data fields to values passed in

setWidth (double newWidth)

setLength(double newLength)

Write a simple test program call TestRectangle like we did in class that creates three Rectangle objects:

rect1 with default values for width and length (call the non-argument constructor)

rect2 with width = 18.5 and length = 33.92

rect3 with width default values for width and length (call the non-argument constructor)

However, you will test the setter methods and set the width and length as follows:

o Set the width as a random number between 5 and 10 (excluding 5 and 10)

o Set the length as a random number between 10 and 20 (excluding 10 and 20)

o Check out Slide #40 Lesson #3 to see how to generate random numbers between two numbers

For each rectangle, print out: o width, length, area, and perimeter o Print each element to 2 significant digits (they are all doubles)
