Create class Rectangle. The class has atributes length and width, each of which

Question

Create class Rectangle. The class has atributes length and width, each of which defaults to 1. It has read-only properties for both length and width. The set accessors should verify that length and width are each floating point numbers greater than 0.0 and less than 20.0. WRITE AN APPLICATION TO TEST CLASS RECTANGLE!

I am pretty sure I have the Rectangle class down, but I am confused on how to test it. Do I create an entirely seperate application with a main().? Points will only be rewarded for those who answer this question correctly. Thanks!
