Swing Examples - Using Borders

Following example showcase how to use borders in a Java Swing application.

We are using the following APIs.

• BorderFactory.createLineBorder() − To create a line border.

• BorderFactory.createEtchedBorder() − To create an etched border.

• BorderFactory.createEmptyBorder() − To create an empty border.

• JPanel.setBorder(border) − To set the desired border to the JPanel.

Example

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.LayoutManager;

import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.border.Border;
import javax.swing.border.EtchedBorder;

public class SwingTester {
   public static void main(String[] args) {
      createWindow();
   }

   private static void createWindow() {    
      JFrame frame = new JFrame("Swing Tester");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

      createUI(frame);
      frame.setSize(560, 200);      
      frame.setLocationRelativeTo(null);  
      frame.setVisible(true);
   }

   private static void createUI(JFrame frame){
      Border blackline = BorderFactory.createLineBorder(Color.black);
      Border raisedetched = BorderFactory.createEtchedBorder(EtchedBorder.RAISED);
      Border loweredetched = BorderFactory.createEtchedBorder(EtchedBorder.LOWERED);
      Border raisedbevel  = BorderFactory.createEtchedBorder(EtchedBorder.LOWERED);
      Border loweredbevel = BorderFactory.createEtchedBorder(EtchedBorder.LOWERED);
      Border empty = BorderFactory.createEmptyBorder();

      JPanel panel = new JPanel();
      LayoutManager layout = new FlowLayout();  
      panel.setLayout(layout);       

      JPanel panel1 = new JPanel();
      panel1.add(new JLabel("Black border"));
      panel1.setBorder(blackline);

      JPanel panel2 = new JPanel();
      panel2.add(new JLabel("Raised border"));
      panel2.setBorder(raisedetched);

      JPanel panel3 = new JPanel();
      panel3.add(new JLabel("Lowered border"));
      panel3.setBorder(loweredetched);

      JPanel panel4 = new JPanel();
      panel4.add(new JLabel("Raised Bevel border"));
      panel4.setBorder(raisedbevel);

      JPanel panel5 = new JPanel();
      panel5.add(new JLabel("Lowered Bevel border"));
      panel5.setBorder(loweredbevel);

      JPanel panel6 = new JPanel();
      panel6.add(new JLabel("Empty border"));
      panel6.setBorder(empty);

      panel.add(panel1);
      panel.add(panel2);
      panel.add(panel3);
      panel.add(panel4);
      panel.add(panel5);
      panel.add(panel6);

      frame.getContentPane().add(panel, BorderLayout.CENTER);    
   }
