    Default swing doubt

    I wrote the following code where i can add button's at run time(give button name and click on button).
    What i want is :-) How can i perform a specific action if a run-time added button is pressed.................. SUGGEST ME

    Java Code:
    import javax.swing.*;
    import java.awt.*;
    import java.util.*;
    import java.awt.event.*;
    public class ALD2 implements ActionListener
    {
    		JButton button;
    		JTextField jtf1;
    		JFrame frame;
    		
    		public static void main(String args[])
    		{
    		ALD2 ald=new ALD2();	
    		ald.go();
    		}
    
    		void go()
    		{
    		frame=new JFrame();
    		button=new JButton("click me");
    		jtf1=new JTextField(20);
    		frame.getContentPane().add(BorderLayout.EAST,button);
    		frame.getContentPane().add(BorderLayout.CENTER,jtf1);
    		button.addActionListener(this);
    		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		frame.setSize(300,300);
    		frame.setVisible(true);
    		}
    
    		public void actionPerformed(ActionEvent ae)
    		{
    		String str=jtf1.getText();
    
    
    		if(ae.getSource()==button)
    		{
    		frame.getContentPane().add(new JButton(str);
                                frame.validate();
                                frame.repaint();
    		}
    		
    		}
    }

    You have to add an ActionListener to it, exactly like any other JButton.
