How to customize how a JTabbedPane looks in Java?

To customize how a JTabbedPane looks, change its font style, font face, font size and the background and foreground colors.

Let’s say the following is the JTabbedPane −

JTabbedPane tabbedPane = new JTabbedPane();

Now, let us customize the above created JTabbedPane −

tabbedPane.setBackground(Color.orange);
tabbedPane.setForeground(Color.white);
Font font = new Font("Verdana", Font.CENTER_BASELINE, 18);
tabbedPane.setFont(font);

The following is an example to customize JTabbedPane −

Example

package my;
import javax.swing.*;
import java.awt.*;
public class SwingDemo {
   public static void main(String args[]) {
      JFrame frame = new JFrame("Technologies");
      JTabbedPane tabbedPane = new JTabbedPane();
      JPanel panel1, panel2, panel3, panel4, panel5;
      panel1 = new JPanel();
      panel2 = new JPanel();
      panel3 = new JPanel();
      panel4 = new JPanel();
      panel5 = new JPanel();
      tabbedPane.addTab("Data Science", panel1);
      tabbedPane.addTab("Blockchain ", panel2);
      tabbedPane.addTab("PHP", panel3);
      tabbedPane.addTab("Matlab ", panel4);
      tabbedPane.addTab("Servlet", panel5);
      tabbedPane.setBackground(Color.orange);
      tabbedPane.setForeground(Color.white);
      Font font = new Font("Verdana", Font.CENTER_BASELINE, 18);
      tabbedPane.setFont(font);
      frame.add(tabbedPane);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setSize(660,350);
      frame.setVisible(true);
   }
}
