Hi Friend,

Try the following code:

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

public class SwingProgram extends JFrame{

public JButton b = new JButton("Add");
public JTextField text = new JTextField(15);
public JPanel panel = new JPanel();
public SwingProgram() {
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (e.getActionCommand().equals("Add")) {
}else if (e.getActionCommand().equals("Remove")) {
public static void main(String[] args) {
SwingProgram p = new SwingProgram();
