The most user-friendly interfaces are usually obtained by using the default
appearance (font, color, background), but there are cases where you want to
change these.
Appearance: setting the font
The font of a JLabel can be changed like this.
JLabel title = new JLabel("Want a Raise?", JLabel.CENTER);
title.setFont(new Font("Serif", Font.BOLD, 4);
Appearance: setting the text color
Use the setForeground method to set the text color.
JLabel title = new JLabel("Want a Raise?", JLabel.CENTER);
title.setForeground(Color.white);
Appearance: setting the background color
Because a JLabel's background is transparent, there is no effect from using the
setBackground method. To make a new background, you need to create a JPanel with
the appropriate color and put the label on that. For example
JLabel title = new JLabel("Want a Raise?");
title.setForeground(Color.white);
JPanel titlePanel = new JPanel();
titlePanel.setBackground(Color.blue);
titlePanel.add(title); // adds to center of panel's default BorderLayout.
