How to disable a Tab in a JTabbedPane Container with Java?

To disable a tab in a JTabbedPane container, use the setEnabledAt() method and set it to false with the index of the tab you want to disable.

Let’s first create a JTabbedPane −

JTabbedPane tabbedPane = new JTabbedPane();

Now, let us disable a tab at index 2 −

tabbedPane.setEnabledAt(2, false);

The following is an example to disable a tab in a JTabbedPane Container −

Example

package my; import javax.swing.*; import java.awt.*; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Devices");       JTabbedPane tabbedPane = new JTabbedPane();       JTextArea text = new JTextArea(100,100);       JPanel panel1, panel2, panel3, panel4, panel5, panel6, panel7, panel8;       panel1 = new JPanel();       panel2 = new JPanel();       panel2.add(text);       panel3 = new JPanel();       panel4 = new JPanel();       panel5 = new JPanel();       panel6 = new JPanel();       panel7 = new JPanel();       panel8 = new JPanel();       tabbedPane.setBackground(Color.yellow);       tabbedPane.setForeground(Color.black);       tabbedPane.addTab("Laptop", panel1);       tabbedPane.addTab("Desktop ", panel2);       tabbedPane.addTab("Notebook", panel3);       tabbedPane.addTab("Echo ", panel4);       tabbedPane.addTab("Tablet", panel5);       tabbedPane.addTab("Alexa ", panel6);       tabbedPane.addTab("Notebook", panel7);       tabbedPane.addTab("iPad", panel8);       tabbedPane.setEnabledAt(2, false);       tabbedPane.setEnabledAt(5, false);       frame.add(tabbedPane);       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       frame.setSize(550,350);       frame.setVisible(true);    } }

The output is as follows. Here, we have disabled the tabs with index 2 and 5 −
