Extracted text: Shape Classes Design classes Square, RightTriangle , and Triangle that encapsulate three geometric shapes. Each class should implement a method void draw (int x, int y) that “draws" a square, a right triangle, or an equilateral triangle (a triangle with three equal sides), respectively. See Figure 2. The parameters x and y specify the relative position of the figure: y lines down and x spaces acro from the current position of the screen cursor. The instance variables of each class are: int rows , the number of rows that comprise the figure, and char character , the keyboard character used for drawing the figure. Each shape of Figure 2 consists of five rows. The drawing characters are *** for the square, %' for the right triangle, and #' for the equilateral triangle.

Provide an implementation of the classes. b. Create a TestShape class that will allow the Shape class to polymorph to the subclasses. Call the constructor method and draw the corresponding shape by calling the draw method.
