How do I create a compound border? - Learn Java by Examples

In this example we create a compound border, a border around border. Here, instead of creating a new instance of Border class directly we create the border using the BorderFactory factory class.

package org.kodejava.swing;

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

public class CompoundBorderExample extends JFrame {
    public CompoundBorderExample() {
        initializeUI();
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(
                () -> new CompoundBorderExample().setVisible(true));
    }

    private void initializeUI() {
        setSize(500, 500);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        setLayout(new FlowLayout(FlowLayout.LEFT));

        BevelBorder raisedBevel =
                (BevelBorder) BorderFactory.createBevelBorder(BevelBorder.RAISED);
        BevelBorder loweredBevel =
                (BevelBorder) BorderFactory.createBevelBorder(BevelBorder.LOWERED);
        Border border = BorderFactory.createCompoundBorder(raisedBevel, loweredBevel);
        JPanel panel = new JPanel();
        panel.setBorder(border);

        setContentPane(panel);
    }
}
