Class Participation Exercise 12

Proper completion of this exercise is considered as part of course participation. An answer will be discussed in class.

You have a design where a two-dimensional rectangle drawing method takes a top left point and a bottom right point. Also, in your design, the points are specified by integer x and y coordinates.

public interface RectangleDrawer { public void draw( Point topLeft, Point bottomRight ); } Suppose, however, you want to reuse a rectangle drawing method that takes four integer parameters: top left x coordinate, top left y coordinate, width, and height.

public class RectangleRenderer { public void render( int x, int y, int width, int height ) { ... } ... } Write Java code for a rectangle drawing object adapter.

public class RectangleDrawerAdapter ... Submit your Java code as a zip archive.
