JAVA. I am trying to find the area and perimeter of a rectangle and it wont print the results.

Exercise $8\mathrm{.}4$ JHTP $($Rectangle Class$)$: Create a class Rectangle with attributes length and

width, each of which defaults to $1.$ Provide methods that calculate the rectangle$$s perimeter and

area. Use set and get methods for both length and width. The set methods will verify that length

and width are each floating$-$point numbers larger than $0\mathrm{.}0$ and less than $20\mathrm{.}0.$ Write a program to

test class Rectangle.
