[填空題] 下列JApplet使用重寫paintCompon6t()方法來繪制圖像，請?zhí)顚懻_的代碼在橫線處。

import java.awt.*;

import javax.swing.*;

public class Test extends JApplet

staic String fileName = "img().gif";

public void init()

Container cp = getContentPane();

cp.setLayout(new GridLayout(1,1));

Image i = getImage(getCodeBase(),fileName);

MyImagePanel ip=new MyInmagePanel(i);

cp. add (ip);

class MyImagePanel extends JPanel

Image i;

public MyImagePanel(Image img)

this.i = img;

public void paintComponent(Graphics gg)

【15】 ;

gg.drawImage(i,20,20,this);

super.paintComponent(gg)

在Panel子類中重寫paintComponent()方法，必須在繪制圖像之前調用super.paintComponent()方法來對構件的背景進行繪制。
