JPanel not showing up.

[heavy frigate]

    void drawOtherPanel() {
        System.out.println("TEST PRINT"); // this gets printed
        
        removePanels();
        
        mainPanel.add(otherPanel);
        
        validate();
        repaint();
    }

I'm working with some swing graphics code. I have this method which is supposed to draw a certain panel when a button is clicked, but it does nothing. Why does it not work?

what does the removePanels() do?

you must set the layout properly too

[heavy frigate]

It removes all the other panels from mainPanel.

[fathom tundra]

set a layout before adding them to the mainPanel

[heavy frigate]

I used absolute layout for otherPanel.
