Answer 1

You've added the button to the SOUTH position of a BorderLayout. This is the default behaviour of BorderLayout.

To fix it, create another JPanel, add your button to it, then add the panel to the SOUTH position instead

Take a look at

• A visual guide to layouts
• Using Layout Managers

The approach mentioned above is commonly known as compound layouts, as you use a series of containers with different layout managers to achieve the desired effect.

JPanel buttonPane = new JPanel(); // FlowLayout by default
JButton okayButton = new JButton("Ok");
buttonPanel.add(okayButton);
add(okayButton, BorderLayout.SOUTH);
