Borders

• Place a border around a panel to group its contents visually
• EtchedBorder: three-dimensional etched effect
• Can add a border to any component, but most commonly to panels:

  JPanel panel = new JPanel();
  panel.setBorder(new EtchedBorder());

• TitledBorder: a border with a title

  panel.setBorder(new TitledBorder(new EtchedBorder(), "Size"));
