In this article, we will learn how to display a table with multiple rows and columns in Java using the JTable component. Additionally, we will demonstrate how to remove the first row from the table using the removeRow() method. The first program shows how to create and display a table with 9 rows, and the second program demonstrates how to remove the first row, leaving the remaining 8 rows intact.  Create a table with rows and columns using JTable Following are the steps to create a table with rows and columns using JTable − Start ...

To move the first row to the end of the table in Java, use the moveRow() method. It has three parameters. The first two parameters allows you to set the starting and ending row index to be moved. The last parameter sets the destination of the rows to be moved.As discussed above, move the first row to the end −tableModel.moveRow(0, 0, tableModel.getRowCount() - 1);The following is an example to move the first row to the end of the table −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 ...

Use the Font class to set font for text. Let us first create JTextPane component −JTextPane textPane = new JTextPane();Now, set the font with the Font class setFont() method −Font font = new Font("Serif", Font.ITALIC, 18); textPane.setFont(font);The following is an example to set font for text −Examplepackage my; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Container; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTextPane; import javax.swing.text.BadLocationException; import javax.swing.text.SimpleAttributeSet; import javax.swing.text.Style; import javax.swing.text.StyleConstants; import javax.swing.text.StyledDocument; public class SwingDemo {    public static void main(String args[]) throws BadLocationException {       JFrame frame = new JFrame("Demo");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       ...

In the given article, we will learn to write a program in Java to increase the row height in a JTable. The example creates a table with different languages and their difficulty levels and then modifies the row height using the setRowHeight() method. Steps to increase the row height in a JTable  Following are the steps to increase the row height in a JTable − Import the necessary classes from javax.swing package. Initialize a DefaultTableModel and create a JTable with it. Add columns to represent languages and ... Read More

Composed border consists of two or more borders i.e. border around a border. We can create it for a component in Java using the createCompoundBorder() method.Let’s say the following is our component −JLabel label; label = new JLabel("This has compound border (border around a border)!");Now, set the compound border −label.setBorder(BorderFactory.createCompoundBorder(BorderFactory    .createRaisedBevelBorder(), BorderFactory.createLoweredBevelBorder()));The following is an example to create a compound border for a component −Examplepackage my; import javax.swing.BorderFactory; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JLabel; public class SwingDemo {    public static void main(String[] args) throws Exception {       JFrame frame = new JFrame("Demo");       JLabel ...

To create a titled border for a component in Java, use the createTitledBorder() method. Let’s say we have a panel and we need to set a titled border to it. Here’s our panel −JPanel panel = new JPanel();Now, set the border and set the text for the tites border −panel.setBorder(BorderFactory.createTitledBorder(    BorderFactory.createEtchedBorder(), "My Demo Table", TitledBorder.LEFT, TitledBorder.TOP));The following is an example to create a titled border −Examplepackage my; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.border.TitledBorder; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame();   ...

To set the the color of a single tab’s text, use the setForegroundAt() method. This gives an option to mention the index and the color. The index here is the index of the specific tab you want to color the text.Let us first create a JTabbedPane −JTabbedPane tabbedPane = new JTabbedPane();Now, set the background color for one of the tabs with index 2 −tabbedPane.setForegroundAt(2, Color.RED);The following is an example wherein we will update the foreground color of a single tab in the JTabbedPane −Examplepackage my; import javax.swing.*; import java.awt.*; public class SwingDemo {    public static void main(String args[]) { ...

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 −Examplepackage 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); ...

To enable scrolling tabs in a JTabbedPane container, use the setTabLayoutPolicy() method −tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);Above, we have set the constant to be SCROLL_TAB_LAYOUT, since we want the scroller to be visible when all the tabs won’t fit within a single run.The following is an example to enable scrolling tabs in a JTabbedPane container −Examplepackage 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, ...

At first, create a table with DefaultTableModel −String data[][] = {    {"Australia", "5", "1"},    {"US", "10", "2"},    {"Canada", "9", "3"},    {"India", "7", "4"},    {"Poland", "2", "5"},    {"SriLanka", "5", "6"} }; String col [] = {"Team", "Selected Players", "Rank"}; DefaultTableModel tableModel = new DefaultTableModel(data, col); JTable table = new JTable(tableModel);Now, use the getModel() to retrieve the value from table cell −Object ob = table.getModel().getValueAt(3, 2); System.out.println("Value = "+ob);The following is an example to retrieve the value from a table cell with TableModel −Examplepackage my; import java.awt.Dimension; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JRootPane; import javax.swing.JScrollPane; import ...
