Hi Friend,

Try the following code:

import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.html.*;

public class Copy {
final static int interval = 1000;
int i;
JLabel label;
JProgressBar pb;
Timer timer;
JButton button;

public Copy() {
JFrame frame = new JFrame("Swing Progress Bar");
button = new JButton("Start");
button.addActionListener(new ButtonListener());

pb = new JProgressBar(0, 20);
pb.setValue(0);
pb.setStringPainted(true);

label = new JLabel(" ");
JPanel panel = new JPanel();
panel.add(button);
panel.add(pb);
JPanel panel1 = new JPanel();
panel1.setLayout(new BorderLayout());
panel1.add(panel, BorderLayout.NORTH);
panel1.add(label, BorderLayout.CENTER);
panel1.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
frame.setContentPane(panel1);
frame.pack();
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

timer = new Timer(interval, new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if (i == 20) {
Toolkit.getDefaultToolkit().beep();
timer.stop();
button.setEnabled(true);
pb.setValue(0);
String str = "<html>" + "" + ""
+ "File is copied." + "" + ""
+ "</html>";
label.setText(str);
}
i = i + 5;
pb.setValue(i);
}
});
}

class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent ae) {
button.setEnabled(false);
i = 0;
String str = "<html>" + "" + ""
+ "Copying File......." + "" + "" + "</html>";
label.setText(str);
timer.start();
try {
File f1 = new File("C:/UploadedFiles/file.txt");
File f2 = new File("C:/Hello/file.txt");
InputStream in = new FileInputStream(f1);
OutputStream out = new FileOutputStream(f2, true);
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();

} catch (Exception e) {
}
}
}

public static void main(String[] args) {
Copy spb = new Copy();
}
}

Thanks
