How can we implement different borders using the BorderFactory in Java?n

The BorderFactory is a Factory class which provides different types of borders in Java.

Types of Borders

• BevelBorder: This border draws raised or lowered beveled edges.
• EmptyBorder:  It doesn’t do any drawing, but does take up space.
• EtchedBorder: A Lowered etched border gives an appearance of a rectangle and a Raised etched border looks like a surface of the screen.
• LineBorder: Draws a simple rectangle around a component. We can specify the color and width of the line in the LineBorder constructor.
• MatteBorder: We can create a MatteBorder with a certain color and specify the size of the border on the left, top, right, and bottom of the component. A MatteBorder also allows us to pass an Icon that will be used to draw the border. This can be an image (ImageIcon) or any other implementation of the Icon interface.
• TitledBorder: A regular border with a title. A TitledBorder doesn’t actually draw a border; it just draws a title in conjunction with another border object. This border type is particularly useful for grouping different sets of controls in a complicated interface.
• Component Border: A border that contains two other borders. This is especially handy if we want to enclose a component in an EmptyBorder and then put something decorative around it, such as an EtchedBorder or a MatteBorder.

         add(createBorderedPanel(BorderFactory.createLineBorder(Color.red), "createLineBorder(Color.red)"));
         add(createBorderedPanel(BorderFactory.createLineBorder(Color.blue, 5), "createLineBorder(Color.blue, 5)"));
         add(createBorderedPanel(BorderFactory.createDashedBorder(null), "createDashedBorder(null)"));
         setLocationRelativeTo(null);
      }
   }
   private static JPanel createBorderedPanel(Border b, String name) {
      JLabel label = new JLabel(name);
      JPanel panel = new JPanel();
      panel.setBorder(b);
      panel.add(label);
      return panel;
