It depends on how your layout is organised. You can use a JTabbedPane or CardLayout to achieve this.

Try this:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
   secondPanel.setVisible(true);
}

and if you are not adding it before then you have to also add it like:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
   add(secondPanel);
   secondPanel.setVisible(true);
}

Try this:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    TheConductor conduct = new TheConductor();
    add(conduct);
    conduct.setVisible(true);
}

sorry, it cannot work , it says non-static method setVisible(boolean) cannot be referenced from a static context – George Lim May 20 '11 at 05:54
@George Lim: is your `TrainAndConductor` variable global and accessible by this method? – Harry Joy May 20 '11 at 05:56
@George: You must create the `TrainAndConductor` panel before, and then call the method setVisible on the object: `myTrainAndConductorObject.setVisible(true);` – Jonas May 20 '11 at 05:56
@George: We know that. It would be helpful if you could provide more code. – Jonas May 20 '11 at 06:02
i have edited the code, some codes are for other purpose just ignore it. – George Lim May 20 '11 at 06:21
@George: okay. Now just create constructor of the TheConductor class in actionPerformed and in the constructor of TheConductor use `setVisible(true);`. Note that you also have to provide size of TheConductor may be you are providing in initComponents() of TheConductor. – Harry Joy May 20 '11 at 06:43
thanks man . it works now . and also last question. what method should i implement to close the TrainAndConductor Panel. public TheConductor() { initComponents(); setVisible(true); //close action – George Lim May 20 '11 at 06:55
@George: it depends on meaning of close. If you just wanna hide and preserve data then use `setVisible(false);` – Harry Joy May 20 '11 at 06:56
it works after i remove a bunch of code in TheConductor which are below. public static void main(String args[]) { java.awt.EventQueue.invokeLater(new Runnable() { public void run() { new TheConductor().setVisible(true); } }); } – George Lim May 20 '11 at 06:58
what i meant was , let say there are 2 panels there, once i click the button on the 1st panel and it brings me to the second panel in the mean time, it will also close my first panel. – George Lim May 20 '11 at 07:03
@George: add `setVisible(false);` after you create TheConstructor object in first frame. This will hide first frame. – Harry Joy May 20 '11 at 07:04
sorry sir, i dont get it, where should i add setVisible(false); ? – George Lim May 20 '11 at 07:13
@George: `private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { TheConductor conduct = new TheConductor(); setVisible(false); }` – Harry Joy May 20 '11 at 07:16
@Harry hi, but my current setVisible is true , how can i set it to false again ? `private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { TheConductor conduct = new TheConductor(); add(conduct); conduct.setVisible(false);` – George Lim May 20 '11 at 07:30
`private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { TheConductor conduct = new TheConductor(); conduct.setVisible(true); setVisible(false); }` – George Lim May 20 '11 at 07:36
