(TCO 2) What is the result of the following code? JFrame frame = new JFrame( ); frame.add(new JButton(One), BorderLayout.NORTH); frame.add(new JButton(Two), BorderLayout.NORTH); frame.setVisible(true);

Two buttons are added side by side at the top of the display.

Button One was added first, so it is the only button at the top of the display.

The Java compiler will not allow you to add two buttons to the same area.
