This is a JAVA problem.

In this assignment you are going to create a Rectangle class to perform certain operations that are relevant to rectangles. Also, you will create a RectangleTest class to demonstrate its functionality.

Rectangle class should have length and width parameters to account for two sides. Area is not an instance variable; it is something that can be calculated once the user calls getArea().

The methods you should have:

• Rectangle() //default constructor that sets 0 to both length and width
• Rectangle(int, int) //constructor that initializes both variables.
• toString() //returns a string to display rectangle information
• isSquare() //method to check if length equals width. If it is, returns true.

You should create 3 rectangles in your system. Then use toString method to display the rectangle information.

A sample code block in the main should look something like (for 1 rectangle):

Rectangle r1 = new Rectangle(10,10); System.out.println(r1); //dont forget, this call means return the string coming from r1.toString().

And this should display something like***:

A new object defined. Length: 10 Width: 10 This object is a square. 

***So arrange your toString() method accordingly
