change JPanel after clicking on a button

I'm building simple GUI for my app. I have couple of JPanels. I want to display them depending on action that was performed by clicking on a JButton. How can I disable one JPanel and enable another one ?

Couple of details. I have a class with JFrame where I'm building starting gui. Where I have buttons and some text. Clicking on one of the buttons should change the view in this JFrame

my button definition

    JButton btnStart = new JButton("Start");
    btnStart.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {

        }
    });
    btnStart.setBounds(10, 11, 110, 23);
    contentPane.add(btnStart);

// edit

I've found the problem. buttons were in static method

First remove the jPanel and add the new jPanel. Then use validate to perform relayout.

    jFrame.remove(jPanelOld);
    jFrame.add(jPanelNew);
    jFrame.validate();

Simple as:

jframe.setContentPane(your_new_panel);
jframe.invalidate();
jframe.validate();

  1. You may want to use CardLayout.
  2. Or you can simple remove the oldpanel and add new panel:
contentPane.remove(oldPanel);
contentPane.add(newPanel);
