(Java)Fill in the missing code below in the init() method and the actionPerformed() method. Instead of drawing the image in paint(), the drawing is done in the actionPerformed() since the source of the ActionEvent object determines the image to draw (this seems to sometimes cause the image not to draw the first time unless a double click is performed).
