Hi Friend,

Try the following code:

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

class ProgressTest extends JFrame {
Timer timer;
final static int interval = 1000;
JProgressBar pb = new JProgressBar();
JButton progress1 = new JButton("Progress1");
JButton progress2 = new JButton("Progress2");
int i;
ProgressTest() {
setLayout(null);
setTitle("Progress Test");
setSize(600, 600);
pb.setBounds(100, 100, 100, 20);
progress1.setBounds(250, 100, 100, 20);
progress2.setBounds(250, 200, 100, 20);
pb.setMaximum(100);
progress1.addActionListener(new ActionListener(){
public void actionPerformed (ActionEvent event) {
pb.setValue(pb.getValue() + 10);
}
});
progress2.addActionListener(new ButtonListener());
pb.setValue(10);
add(pb);
add(progress1);
add(progress2);
timer = new Timer(interval, new ActionListener() {
public void actionPerformed (ActionEvent event) {
if (i == 100){
Toolkit.getDefaultToolkit().beep();
timer.stop();
pb.setValue(0);
}
i = i + 5;
pb.setValue(i);
}
});
}
class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent ae) {
progress2.setEnabled(false);
i = 0;
timer.start();
}
}
public static void main (String [] args) {
ProgressTest obj = new ProgressTest();
obj.setVisible(true);
obj.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

Thanks
