i want to ignore actionPerformed of toolBar class and listen to my another's class actionPerformed

Answer 1

Rather than trying to use the ToolBarDemo class as-is you can use/modify the methods in it for your own class, like this:
import java.awt.*;
import java.awt.event.*;
import java.net.URL;
import javax.swing.*;
import javax.swing.text.TextAction;
public class ToolBarIconTest implements ActionListener
    static final private String OPEN  = "open";
    static final private String SAVE  = "save";
    static final private String COPY  = "copy";
    static final private String PASTE = "paste";
    public void actionPerformed(ActionEvent e)
        String cmd = e.getActionCommand();
        if (OPEN.equals(cmd))
            System.out.println("show a JFileChooser open dialog");
        if (SAVE.equals(cmd))
            System.out.println("show a JFileChooser save dialog");
    private JToolBar getToolBar()
        JToolBar toolBar = new JToolBar();
        addButtons(toolBar);
        return toolBar;
    protected void addButtons(JToolBar toolBar) {
        JButton button = null;
        //first button
        button = makeGeneralButton("Open24", OPEN,
                                   "To open a document",
                                   "Open", this);
        toolBar.add(button);
        //second button
        button = makeGeneralButton("Save24", SAVE,
                                   "To save a document",
                                   "Save", this);
        toolBar.add(button);
        //third button
        button = makeGeneralButton("Copy24", COPY,
                                   "Copy from focused text component",
                                   "Copy", copy);
        toolBar.add(button);
        //fourth button
        button = makeGeneralButton("Paste24", PASTE,
                                   "Paste to the focused text component",
                                   "Paste", paste);
        toolBar.add(button);
    protected JButton makeGeneralButton(String imageName,
                                        String actionCommand,
                                        String toolTipText,
                                        String altText,
                                        ActionListener l) {
        //Look for the image.
        String imgLocation = "toolbarButtonGraphics/general/"
                             + imageName
                             + ".gif";
        URL imageURL = ToolBarIconTest.class.getResource(imgLocation);
        //Create and initialize the button.
        JButton button = new JButton();
        button.setActionCommand(actionCommand);
        button.setToolTipText(toolTipText);
        button.addActionListener(l);
        if (imageURL != null) {                      //image found
            button.setIcon(new ImageIcon(imageURL, altText));
        } else {                                     //no image found
            button.setText(altText);
            System.err.println("Resource not found: "
                               + imgLocation);
        return button;
    private Action copy = new TextAction(COPY)
        public void actionPerformed(ActionEvent e)
            JTextComponent tc = getFocusedComponent();
            int start = tc.getSelectionStart();
            int end = tc.getSelectionEnd();
            if(start == end)
                tc.selectAll();
            tc.copy();
    private Action paste = new TextAction(PASTE)
        public void actionPerformed(ActionEvent e)
            getFocusedComponent().paste();
    private JPanel getTextFields()
        JPanel panel = new JPanel(new BorderLayout());
        panel.add(new JTextField(12), "North");
        panel.add(new JTextField(12), "South");
        return panel;
    public static void main(String[] args)
        ToolBarIconTest test = new ToolBarIconTest();
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(test.getToolBar(), "North");
        f.getContentPane().add(test.getTextFields());
        f.setSize(360,240);
        f.setLocation(200,200);
        f.setVisible(true);
}Use the -cp option as shown in the ToolBarDemo class comments
C:\jexp>java -cp .;path_to_jar_file/jlfgr-1_0.jar ToolBarIconTest
