How to convert this application into Applet, Thanks!!

Posted: Apr 17, 2006 6:34 AM

Application Programme:
import java.io.*;
import javax.swing.*;
public class filepath
{
public static void main(String[] args)
{
String currentFilePath = null;
File file = null;
String currentFileName = null;
JFileChooser jFileChooser = new JFileChooser();
int result = jFileChooser.showOpenDialog(null);
if(result == JFileChooser.APPROVE_OPTION)
{
currentFilePath = jFileChooser.getSelectedFile().getPath();
try
{
file = new File(currentFilePath);
currentFileName = file.getAbsolutePath();
System.out.println(currentFileName);
currentFileName = file.getParent();
System.out.println(currentFileName);
// ...other code
}
catch(NullPointerException npe)
{
String errorMsg = new String("status: Error by opening " );
System.err.println(errorMsg);
}
}

}
}
Applet Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class MainAccess extends JApplet implements ItemListener{

Container container=getContentPane();

JMenuBar menuBar=new JMenuBar();

JMenu menuFile=new JMenu("ÎÄ¼þ");
JMenuItem inputTerrain=new JMenuItem("ÊäÈëµØÐÎÊý¾Ý");
JPanel panel=new JPanel();
JTextArea text=new JTextArea();
public void init(){
container.setLayout(new FlowLayout());

panel.setLayout(new BorderLayout());
panel.add(text);
container.add(panel);

menuBar.add(menuFile);
inputTerrain.addActionListener(new itemListener());
menuFile.add(inputTerrain);
setJMenuBar(menuBar);
}
public void itemStateChanged(ItemEvent e){

}
class itemListener implements ActionListener{
public void actionPerformed(ActionEvent e){
if(e.getSource()==inputTerrain){
//text.append("ok");
String currentFilePath = null;
File file = null;
String currentFileName = null;
JFileChooser jFileChooser = new JFileChooser();
int result = jFileChooser.showOpenDialog(null);
if(result == JFileChooser.APPROVE_OPTION){
currentFilePath = jFileChooser.getSelectedFile().getPath();
try{
file = new File(currentFilePath);
currentFileName = file.getAbsolutePath();
text.append(currentFileName);
//System.out.println(currentFileName);
currentFileName = file.getParent();
text.append(currentFileName);
//System.out.println(currentFileName);
// ...other code
}
catch(NullPointerException npe){
String errorMsg = new String("status: Error by opening " );
System.err.println(errorMsg);
}

}
}
}
}
}
