Create a Rectangle class that models a Rectangle. It should have integer length and width attributes. The Rectangle class should also be able to draw a rectangle on the standard output device, using a single character that is specified by the user, and should compute the area and perimeter of rectangles. Valid values for length and width are integers in the range 1-30.

Include appropriate get and set methods, and other methods that may be required to adequately model rectangles.

Create a program called TestRectangle that tests the methods in the Rectangle class
