Java Source Code: Create Different Borders of a Label

This is a Java source code for a simple graphical application that demonstrates how to use various types of borders in Swing, a Java GUI toolkit. The program defines a class BorderDemo that extends JApplet, a Swing component used for embedding a Java application in a web page or other container.

In this java code, a method make(Border border, String command) is defined to create a new JLabel with the specified Border object and text label. This method is called multiple time, each time with a different type of border and a label describing the border. The borders are created using the BorderFactory class, which provides convenient methods for creating various types of borders in Swing.

import java.awt.*;
import javax.swing.*;
import javax.swing.border.Border;

public class BorderDemo extends JApplet {

   public void init() {
      setBackground(Color.lightGray);
      getContentPane().setBackground( Color.lightGray );
      getContentPane().setLayout( new GridLayout(0,1,7,7) );
      make(BorderFactory.createLineBorder(Color.red,2),
          "BorderFactory.createLineBorder(Color.red,2)");
      make(BorderFactory.createMatteBorder(2,2,5,5,Color.red),
          "BorderFactory.createMatteBorder(2,2,5,5,Color.red)");
      make(BorderFactory.createEtchedBorder(),
          "BorderFactory.createEtchedBorder()");
      make(BorderFactory.createRaisedBevelBorder(),
          "BorderFactory.createRaisedBevelBorder()");
      make(BorderFactory.createLoweredBevelBorder(),
          "BorderFactory.createLoweredBevelBorder()");
      make(BorderFactory.createTitledBorder("Title Goes Here"),
          "BorderFactory.createTitledBorder(\"Title Goes Here\")");
   }

   void make(Border border, String command) {
         // Make a lable showing the string and with the specified border.
         // The label will be opaque and will have a light gray background.
         // The label is added to the applet's content pane.
      JLabel label = new JLabel(command, JLabel.CENTER);
      label.setBackground(Color.lightGray);
      label.setOpaque(true);
      label.setBorder(border);
      getContentPane().add(label);
   }

   public Insets getInsets() {
        // Leave a border around the applet where the background
        // color will show through.
      return new Insets(7,7,7,7);
   }

} // end class JApplet
