    }

    frame.add(panel,panel2);        
    frame.setVisible(true);

Don't use a `null` layout. Use a [real layout](https://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html) that positions them like you want. — resueman, May 09 '16 at 23:54
Instead of `panel.setLayout(null)` use a not null Layout, choose one from the link @resueman shared. examples are given on the site. — Mad Matts, May 10 '16 at 00:00

You can think of the JPanel as one big panel that contains the all of the other elements. So you can have a main JPanel and then put others inside it. You should set a layout that fits your needs to the main panel. A good introduction to layouts can be found here http://docs.oracle.com/javase/tutorial/uiswing/layout/index.html
