Develop a class called Rectangle with the following members:

Public Class constants DEFAULT$\_$WIDTH with value of $5$

Public Class constants DEFAULT$\_$HEIGHTS with value of $5$

Public Instance Variables width, length, area

Public method initRect that takes as input a width and height and sets the corresponding member values to these values$$the method returns nothing

Public method computeArea that computes area and saves it as the variable area

Public method getArea that returns the area of the object

Public method setWidth that sets the width of the object to the corresponding value supplied by the input parameter

Public method setLength that sets the length of the object to the corresponding value supplied by the input parameter

Provide the body of a main program that would perform the following:

Creates an object of the class Rectangle called r

Initializes the object with a value of $5$ for width and the content of the variable y as length

Computes the area of r

Gets the area of the object and displays it to the user via the System.out command
