Yes, we can save the content to a file with FileWriter class. Set a JTextFile component as shown below −JTextField emailId = new JTextField(20); emailId.setText("abc@example.com");Set the file location from to where you want to save the content from the JTextField −String file = "E:ew.txt";Now, with FileWriter, save the content −FileWriter fileWriter = new FileWriter(file); emailId.write(fileWriter); fileWriter.close();The following is an example to save content from JTextFile to a file. Here, we are saving the text from JTextField to a file at location: “E:ew.txt” −Examplepackage my; import java.awt.FlowLayout; import java.io.FileWriter; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextField; import javax.swing.SwingConstants; public class SwingDemo { ...

To create right justified JTextField, set the alignment to be RIGHT. Here, we will be using the setHorizontalAlignment() method as well and within that the alignment would be set.Create a JTextField −JTextField emailId = new JTextField(20);Now, align it to the right −emailId.setHorizontalAlignment(JTextField.RIGHT);The following is an example to create right justified JTextField −Examplepackage my; import java.awt.FlowLayout; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextField; import javax.swing.SwingConstants; public class SwingDemo {    public static void main(String[] args) throws Exception {       JFrame frame = new JFrame("Enter emailid...");       JLabel label;       frame.setLayout(new FlowLayout());       label = ...

To change the minimum value of a slider in Java, use the setMinimum() method wherein set the minimum value.Let’s say the following is our slider in Java −JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 55); slider.setMinorTickSpacing(10); slider.setMajorTickSpacing(20); slider.setPaintTicks(true); slider.setPaintLabels(true);Now, set the minimum value −slider.setMinimum(10);The following is an example to change the minimum value of a JSlider −Examplepackage my; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JSlider; import javax.swing.WindowConstants; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame("Frame with Slider");       JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, ...

Use the setVgap() method to set the vertical gap between elements in a GridLayout. Let’s say we have a GridLaypout −GridLayout layout = new GridLayout(3, 3);Set the horizontal gap −layout.setVgap(30);The following is an example −Examplepackage my; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Font; import java.awt.GridLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextArea; import javax.swing.WindowConstants; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame("Sections");       JPanel panel = new JPanel();       panel.setBackground(Color.blue);       GridLayout layout = new GridLayout(3, 3);     ...

To display tick marks in a JSlider, you need to use the setPaintTicks() method and set it to TRUE −JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 75); slider.setPaintTicks(true);The following is an example to display tick marks in a slider in Java −Examplepackage my; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JSlider; import javax.swing.WindowConstants; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame("Frame with Slider");       JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 75);       slider.setMinorTickSpacing(5);       slider.setMajorTickSpacing(20);       slider.setPaintTicks(true);   ...

Remove a menu from the MenuBar using the remove() method. Set the index for the menu you want to remove from the MenuBar.Let’s say we have the following two menus initially −The following is an example to remove one the above menus. Let’s say we are removing the 2nd menus “Edit” −Examplepackage my; import java.awt.event.KeyEvent; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; public class SwingDemo {    public static void main(final String args[]) {       JFrame frame = new JFrame("MenuBar Demo");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JMenuBar menuBar = new JMenuBar();       JMenu ...

To hide the track on the slider, you need to use the setPaintTrack() method and set it to FALSE −JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 55); slider.setInverted(true); slider.setMinorTickSpacing(10); slider.setMajorTickSpacing(25); slider.setPaintTicks(true); slider.setPaintLabels(true); slider.setPaintTrack(false);The above method setPaintTrack() is by default set to TRUE.The following is an example to hide the track on the slider −Examplepackage my; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JSlider; import javax.swing.WindowConstants; public class SwingDemo {    public static void main(String[] args) {       JFrame frame = new JFrame("Frame with Slider");       JSlider slider = new JSlider(JSlider.HORIZONTAL, 0, 100, 55);   ...

Use the createRaisedBevelBorder() method to create a border with a raised beveled edge. We will set it on the label component −JLabel label; label = new JLabel("This has a border with a raised bevel edge!"); label.setBorder(BorderFactory.createRaisedBevelBorder());The following is an example to create a border with a raised beveled edge −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 label;       label = new JLabel("This has a border with a raised bevel edge!"); ...
