Modify the Java code so that when the ball bounces off some wall (right, left, top, bottom), either the color changes, the shape changes (to rectangle say), or the size changes (bigger, smaller etc.). Make your Java code changes to the possible combinations of color, shape, size, etc. and capture the screens. 1 5 5 7 3 3 2 1 2 3 ie 5 5 7 3 L 2 3 1 2 3 1 5 5 3 3 5 import java.awt.*; public class Ball extends JFrame { private int x = 70, xChange = 7; private int y = 50, yChange = 2; private int diameter = 10; private int rectLeftx=50, rectRightX = 300; private int rectTopY= 50, rectBottomY = 300; public void paint (Graphics g) ( } O /** super.paint (g); g.drawRect (rectLeftx, rectTopy, for (int n = 1; n < 1000; n++) { Color backgroundColour = getBackground(); g.setColor (backgroundColour); g. filloval (x, y, diameter, diameter); if (x + xChange <= rectLeftX) xChange = -xChange; rectRightx rectLeftX, rectBottomY rectTopY); if (x+xChange + diameter >= rectRightX) xChange-xchange; if (y+yChange <= rectTopy) yChange-yChange; . if(y + yChange + diameter >= rectBottomy) yChange-yChange; x = x + xChange; y = y + yChange; try ( } g.setColor (Color.blue); g. filloval (x, y, diameter, diameter); Thread.sleep (20); //Thread.sleep (100); // slow down 10 times for screen capture } catch (InterruptedException e) { g.drawstring ("sleep exception", 20, 20); import javax.swing.
