How to organize my JPanel inside a JFrame?

I'm having trouble organizing JPanel inside a JFrame.

I have 3 JPanels and need to organize them as follows:

panel1 panel2

panel__3333333

However, can only horizontally align panel1 and panel2 as follows:

 groupLayout.setHorizontalGroup(groupLayout.createSequentialGroup()
        .addComponent(PANEL1)
        .addComponent(PANEL2));
    groupLayout.setVerticalGroup(groupLayout.createParallelGroup()
        .addComponent(PANEL1)
        .addComponent(PANEL2));

Thanks.

I think you should use GridBagLayout instead of a grouplayout. It matches with your needs

See the oracle doc on gridbag layout here

The easiest way to accomplish this is to house your JPanels inside of other JPanels.

Here is an example of what you might do:

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

//this is the main JPanel that will house all of your child JPanels
JPanel mainPanel= (JPanel)frame.getContentPane();
mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));
//this JPanel will house "panel1" and "panel2" on top and will go inside the main panel
JPanel topPanel = new JPanel();
topPanel.setLayout(new BoxLayout(topPanel, BoxLayout.X_AXIS));

//add panel1 and panel2 to topPanel here

mainPanel.add(topPanel);

//add panel3 to mainPanel here

frame.pack();
frame.setVisible(true);

There are many different approaches to this, but I find this the easiest. Hope this helps!
