Using BorderFactory to Create Borders

To add a border to a component or container, you can use the java BorderFactory which provides many types of Swing borders. The three steps to creating a border are:

Create a border by instantiating the Border.
Choose border style with the BorderFactory.create... ().
Modify the JComponent (component) with the method setBorder.

LineBorder

This method BorderFactory.createLineBorder(Color, int) creates a single border. The first parameter represents the color and the second, the width of the line.

The following code creates a Border in JLabel and JPanel.

import java.awt.BorderLayout; 
import java.awt.Color; 
import java.awt.Dimension; 
import javax.swing.BorderFactory; 
import javax.swing.JFrame; 
import javax.swing.JLabel; 
import javax.swing.JPanel; 
import javax.swing.border.Border; 

public class BorderFactoryExample extends JPanel{

 public BorderFactoryExample(){
 
 JFrame f = new JFrame("BorderFactoryExample"); 
 f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
 f.setVisible(true); 
 
 JPanel panel = new JPanel(); 
 JLabel label = new JLabel(" lineBorder"); 
 label.setPreferredSize(new Dimension(100, 100)); 
 panel.add(label); 
 panel.setPreferredSize(new Dimension(200,125)); 
 //create a black line border and minimum width 1
 Border lineborder = BorderFactory.createLineBorder(Color.black, 1); 
 //associate with JLabel
 label.setBorder(lineborder); 
 
 f.getContentPane().setLayout(new BorderLayout()); 
 f.add(new JLabel(" "), BorderLayout.NORTH); 
 //adjust to center
 f.add(panel, BorderLayout.CENTER); 
 f.pack(); 
 
 }
 public static void main(String[] args) {
 new BorderFactoryExample(); 
 }
}

Output

EtchedBorder

Etched means engraved in French, either from the outside: EtchedBorder.RAISED, or from the inside: EtchedBorder.LOWERED.

RAISED

Border EtchedBorderRaised = BorderFactory.createEtchedBorder(EtchedBorder.RAISED);

LOWERED

Border EtchedBorderLowered = BorderFactory.createEtchedBorder(EtchedBorder.LOWERED);

RaisedBevelBorder

Creates a border as a loose button with light shades and darker shades for shadows.

 Border RaisedBevelBorder = BorderFactory.createRaisedBevelBorder();

LoweredBevelBorder

Creates a border as a pressed button with light and darker shades for shadows.

Border LoweredBevelBorder = BorderFactory.createLoweredBevelBorder();

MatteBorder

Create a border with 5 parameters, the first 4 process the width of the left, right, top and bottom line, and the last one to color the edges.

Border matteborder = BorderFactory.createMatteBorder(1, 1, 3, 1, Color.blue);

You can also make it prettier by adding an icon that redesigns around the border:

ImageIcon icon = new ImageIcon("etoile.png"); 
Border matteborder = BorderFactory.createMatteBorder(1, 1, 3, 1, icon);

TitledBorder

TitledBorder has five constructors, we chose to make an example with the one that includes all the parameters that allow you to add a title to a border with a specific border style, position, font and color.

Border LoweredBevelBorder = BorderFactory.createLoweredBevelBorder(); 
Border EtchedBorderRaised = BorderFactory.createTitledBorder(LoweredBevelBorder, "title",
 TitledBorder.LEFT,TitledBorder.TOP,  
 new Font("Arial", Font.PLAIN , 13), Color.black);

EtchedBorder

This style combines two styles into one. For example, we want to draw a LineBorder inside RaisedBevelBorder:

Border lineborder = BorderFactory.createLoweredBevelBorder(); 
Border RaisedBevelBorder = BorderFactory.createLineBorder(Color.blue); 
Border EtchedBorderRaised = BorderFactory.createCompoundBorder(lineborder,
 RaisedBevelBorder);
