Yes, we can display a JTabPane with TextArea in one of the tabs. For that, let us first create a JTabbedPane component −JTabbedPane tabbedPane = new JTabbedPane();Now, create a text area you want to set under one of the tabs −JTextArea text = new JTextArea(100, 100);Now, set panels for the tabs. Under one of them, set the text area we created above as shown below −panel2 = new JPanel(); panel2.add(text); panel3 = new JPanel(); panel4 = new JPanel(); panel5 = new JPanel(); panel6 = new JPanel(); panel7 = new JPanel(); panel8 = new JPanel();Now, one by one create different tabs ...

To create two borders for a single component, use the createCompoundBorder() method in Java. Here, we have created LineBorder nd TitledBorder −LineBorder lineBorder = new LineBorder(Color.red); TitledBorder titleBorder = new TitledBorder("Demo Title"); Border border = BorderFactory.createCompoundBorder(lineBorder, titleBorder);Now, set both the borders for a single component −JButton button = new JButton("two borders"); button.setBorder(border);The following is an example to create two borders for a single component −Examplepackage my; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Container; import javax.swing.BorderFactory; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.border.Border; import javax.swing.border.EtchedBorder; import javax.swing.border.LineBorder; import javax.swing.border.TitledBorder; public class SwingDemo {    public static void main(String args[]) {       ...

To display all the titles of the JTabbedPane, let us first get the count of tabs −int count = tabbedPane.getTabCount();Now, loop through the number of tabs in the JTabbedPane. Use the getTitleAt() to get the title of each and every tab −for (int i = 0; i < count; i++) {    String str = tabbedPane.getTitleAt(i);    System.out.println(str); }The following is an example to display all the titles of JTabbedPane tabs on Console −Examplepackage my; import javax.swing.*; import java.awt.*; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Devices");     ...
