It's probobly a layout issue. Try to use something like this

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
 
class MyFrame extends JFrame
{
 
    public MyFrame()
    {
 
     setSize(800,600);
     setTitle("MyFrame");
 
     JPanel panel1 = new JPanel();
     JPanel panel2 = new JPanel();
 
     Container cp = getContentPane();
 
[B][COLOR="Red"]     cp.setLayout(new FlowLayout());[/COLOR][/B]
 
     cp.add(panel1);
     cp.add(panel2);
 
    }
 
 
}
class MyFrame extends JFrame
{
   
    public MyFrame()
    {
    
     setSize(800,600);
     setTitle("MyFrame");

     JPanel panel1 = new JPanel();
     JPanel panel2 = new JPanel();

     Container cp = getContentPane();

[B][COLOR="Red"]     cp.setLayout(new FlowLayout());[/COLOR][/B]

     cp.add(panel1);
     cp.add(panel2);
 
    }
 

}

and what makes you think you get only one panel to show if you do that?

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

My Example will show two panels.
I just wanted to show him how to add a layout to the frame.
If he hasn't done that he will only see one panel.

Well, the contentPane of the the JFrams already has a layout. It simply needs to be used correctly. If you use add without any anchor parameter then according to the documentation
As a convenience, BorderLayout interprets the absence of a string specification the same as the constant CENTER

So, simply calling add(Component) twice, is the same as calling add(Component, CENTER) twice. She should be calling add(Component, CENTER) and add(Component, SOUTH), for example.

Of course, changing the layout (as your post showed) is always an option, but is not, strictly speaking, needed.
