Create the method public void draw(Graphic2D g2) in circle.java and octagon.java. This method should draw the shape at the location given by the instance data x and y. The shape should be drawn in the color specified by the color instance data, and if the shape should be filled with the color, the draw method should fill the shape.

Create a class called ShowShapes with a main method. In the main method create a Frame that is 500 by 500. Set the usual properties of the frame.

Create a ShapeComponent class that extends JComponent. Create the paintComponent method and make it draw a row of Octagons that alternate between being filled and being empty. Then draw a row of colored circles that alternate between being filled and being empty. Add a shapeComponent to the frame created in the previous exercise.

Create a new subclass of GeometricShape called Star. Implement the usual members for the class. Create a draw method that draws a 5 sided star at the location given by the x and y instance data. The star should be drawn in the color specified by the color instance data, and if the star should be filled with the color, the draw method should fill the star. Then add a row of stars to the ShapeComponent. The stars should be randomly colored and alternate between being filled and unfilled.
