Here, we will see how to add a title to an existing Line border. Let’s say we have a label and the border is to be set −LineBorder linedBorder = new LineBorder(Color.blue); TitledBorder titledBorder = BorderFactory.createTitledBorder(linedBorder, "Demo Title"); JLabel label = new JLabel(); label.setBorder(titledBorder);The following is an example to add a title to an existing line border −Examplepackage my; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Container; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.border.LineBorder; import javax.swing.border.TitledBorder; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Demo");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     ...

Yes, we can create nested TitledBorder. Let us first create a component for which we will set the border −JLabel label = new JLabel();Now, we will create the 1st border −TitledBorder border = BorderFactory.createTitledBorder("Top Border"); border.setTitlePosition(TitledBorder.TOP);Following is how we will creater border 2. We have set the 1st border here −TitledBorder border2 = new TitledBorder(border, "Bottom CENTER Border", TitledBorder.CENTER, TitledBorder.BOTTOM);Now, set it for the label component −label.setBorder(border2);The following is an example to create nested TitledBorder in Java −package my; import java.awt.BorderLayout; import java.awt.Container; import javax.swing.BorderFactory; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.border.TitledBorder; public class SwingDemo {    public static ...

To make JTable single selectable in Java, you need to set the selection mode to be SINGE_SELECTION. Let’s say the following is our table −String[][] rec = {    { "001", "Shirts", "40" },    { "002", "Trousers", "250" },    { "003", "Jeans", "25" },    { "004", "Applicances", "90" },    { "005", "Mobile Phones", "200" },    { "006", "Hard Disk", "150" }, }; String[] header = { "ID", "Product", "Quantity" }; JTable table = new JTable(rec, header);Set the selection more to make it single selectable with setSelectionMode() method −table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);Let us see an example to set the ...

Let’s say, we have selected a range of rows using addRowSelectionInterval() as shown in the demo screenshot −Now, we will deselect the above shown selected rows using removeRowSelectionInterval(). The range is to be set here for interval i.e rows 3 to 6 (index 2 to 5) will get deselected −table.removeRowSelectionInterval(2, 5);The following is our example to deselect a range of rows −Examplepackage my; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class SwingDemo {    public static void main(String[] argv) throws Exception {       DefaultTableModel tableModel = new DefaultTableModel();       JTable table = new JTable(tableModel); ...

To disable a MenuItem, use the setEnabled() method and set it to FALSE. Let’s say we have the following MenuBar −JMenuBar menuBar = new JMenuBar();Now, create a Menu −JMenu fileMenu = new JMenu("File"); fileMenu.setMnemonic(KeyEvent.VK_F); menuBar.add(fileMenu);We will now create two MenuItems inside the above Menu −JMenuItem menuItem1 = new JMenuItem("New", KeyEvent.VK_N); fileMenu.add(menuItem1); JMenuItem menuItem2 = new JMenuItem("Open File", KeyEvent.VK_O); fileMenu.add(menuItem2);Now, let us disable the 2nd MenuItem −menuItem2.setEnabled(false);The following is an example to disable a MenuItem in Java −Examplepackage my; import java.awt.Color; import java.awt.event.KeyEvent; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.UIManager; public class SwingDemo {    public static void ...
