Write a complete program in a class named ShowDesign that uses the DrawingPanel to draw the following figure:

Java DrawingPanel close maximize minimize
expected output

The window is 200 pixels wide and 200 pixels tall. The background is white and the foreground is black. There are 20 pixels between each of the four rectangles, and the rectangles are concentric (their centers are at the same point). Use a loop to draw the repeated rectangles.

(The next exercise is a modified version of this program, so you can use the code you write here as a starting point for that exercise.)
