请教高手:此程序可编译,运行,但显示不出来。
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class tianshi
{
public static void main(String[] args)
{
tsF frame = new tsF();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.show();
}
}

//A frame that contains a message panel
class tsF extends JFrame
{
public tsF()
{
setTitle("tianshi");

// add panel to frame
tsP panel = new tsP();
Container contentPane = getContentPane();
contentPane.add(panel);

// get screen dimensions
Toolkit kit = Toolkit.getDefaultToolkit();
Dimension screenSize = kit.getScreenSize();
int screenHeight = screenSize.height;
int screenWidth = screenSize.width;

// center frame in screen
setSize(screenWidth / 2, screenHeight / 2);
setLocation(screenWidth / 4, screenHeight / 4);

// set frame icon and title
Image img = kit.getImage("001.gif");
setIconImage(img);
}
}

/**
A panel that displays a message.
*/

class tsP extends JPanel
{
public void paintComponent(Graphics g)
{
super.paintComponentPresent;

g.drawString("tianshi",
MESSAGE_X, MESSAGE_Y);
}

public static final int MESSAGE_X = 75;
public static final int MESSAGE_Y = 100;
}




为什么这个Applet不能在浏览器显示啊?
