How to add a Tab in JTabbedPane with Java?

Let us first create a JTabbedPane −

JTabbedPane tabbedPane = new JTabbedPane();

Create some panels −

JPanel panel1, panel2, panel3, panel4, panel5; panel1 = new JPanel(); panel2 = new JPanel(); panel3 = new JPanel(); panel4 = new JPanel(); panel5 = new JPanel();

Now, add tabs using the addTab() method and set the panels as well in which the tabs would be visible −

tabbedPane.addTab("PHP", panel1); tabbedPane.addTab("Blockchain ", panel2); tabbedPane.addTab("Matlab", panel3); tabbedPane.addTab("JSP ", panel4); tabbedPane.addTab("Servlet", panel5);

The following is an example to add a tab in JTabbedPane −

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("PHP", panel1);       tabbedPane.addTab("Blockchain ", panel2);       tabbedPane.addTab("Matlab", panel3);       tabbedPane.addTab("JSP ", panel4);       tabbedPane.addTab("Servlet", panel5);       frame.add(tabbedPane);       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       frame.setSize(550,350);       frame.setVisible(true);    } }
