The following GUI application displays four colored filled circles at the four corners of the square. Every time the user clicks on the panel, one of the circles changes to a random color. First, the top left, then the top right, then the bottom left and then the bottom right and so on. However, there are several errors and/or missing lines. For each of the specified lines below choose the correct line. 6 public class Drawing Panel3 extends JPanel { ArrayList<Circle> things = new ArrayList<Circle>(); int x = 50, y = 50, 1 = 100, radius = 50, num = 0; public Drawing Panel3 () { this. set Background (Color.yellow); this. addMouseListener(); things.add(new Circle(x, y)); //top left things.add(new Circle(x , y));// top right things.add(new Circle(x, y)); // bottom? things.add(new Circle(x, y));//bottom } class Circle { int x = 100; int y = 100; Color c = new Color (1, 1, 1); TO 12 14 16 18 22 24 26 28 30 public Circle (int x, int y) { this.x = x; this.y = y; } public void setColor (Color c) { C = new Color (c); } public void draw(Graphics g) { g. set Color (c); g. filloval(x, y, radius, radius); } } class ClickListener extends MouseAdapter { public void mouseClicked (MouseEvent e) { Color c = new Color ((int) (Math.random() * 256), (int) (Math.random() *256), (int) (Math.random() *256)); things.setColor (c); num++; if (num == 4) num = -1; repaint(); } } @Override protected void paint Component (Graphics g) { super.paint Component(g): g. drawRect(x, y, 1, 1); for (int i = 0; i < things [1]; i++) { things.draw(g); 32 34 36 38 40 42 44 46 } } Line 6. should be
