To create a top-bottom split pane, let us create two components and split them −JComponent one = new JLabel("Top Split"); one.setBorder(BorderFactory.createLineBorder(Color.MAGENTA)); JComponent two = new JLabel("Bottom Split"); two.setBorder(BorderFactory.createLineBorder(Color.ORANGE));Now, we will split them. The two components will be split one on top of the other using VERTICAL_PANE constant −JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT, one, two);The following is an example to create a top-bottom split pane in Java −Examplepackage my; import java.awt.Color; import javax.swing.BorderFactory; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JSplitPane; public class SwingDemo {    public static void main(String[] a) {       JFrame frame = new JFrame("SplitPane Demo"); ...

Let’s say we have a menu and within that we need to set the JRadioButtonMenuItem. Here’s the Menu −JMenu editMenu = new JMenu("Edit"); editMenu.setMnemonic(KeyEvent.VK_E); menuBar.add(editMenu);Now, set the editMenu and add it to the MenuBar −JMenu editMenu = new JMenu("Edit"); editMenu.setMnemonic(KeyEvent.VK_E); menuBar.add(editMenu);Now, create Options Menu and add it to the editMenu −JMenu optionsMenu = new JMenu("Options"); optionsMenu.setMnemonic(KeyEvent.VK_O); editMenu.add(optionsMenu);Now, set the JRadioButtonMenuItem and add it to the editMenu created above −ButtonGroup group = new ButtonGroup(); JRadioButtonMenuItem radioMenuItem = new JRadioButtonMenuItem("SmartInsertMode", true); radioMenuItem.setMnemonic(KeyEvent.VK_I); optionsMenu.add(radioMenuItem); group.add(radioMenuItem); JRadioButtonMenuItem radioMenuItem2 = new JRadioButtonMenuItem("SmartDeleteMode"); radioMenuItem.setMnemonic(KeyEvent.VK_D); optionsMenu.add(radioMenuItem2); group.add(radioMenuItem2);The following is an example add JRadioButtonMenuItem in Java −Examplepackage my; ...

To set the alignment of the label’s content along the Y axis on the top, use the setVerticalAlignment() method and set the location. Let us first set a label component. We have set the label background color as well so that we can check the alignment of the label’s content properly −JLabel label = new JLabel("Favourite Movie"); label.setPreferredSize(new Dimension(190, 100)); label.setOpaque(true); label.setBackground(Color.GREEN); label.setForeground(Color.WHITE);Now, we will align the label content along the Y axis on the top by seeting location as TOP −label.setVerticalAlignment(JLabel.TOP);The following is an example to set the alignment of the JLabel content along the Y axis on the ...

Let’s say we added a menu to the MenuBar −JMenuBar menuBar = new JMenuBar(); JMenu fileMenu = new JMenu("File"); fileMenu.setMnemonic(KeyEvent.VK_F); menuBar.add(fileMenu);Add the glue component in between the menus to align some of them on the right, for example −menuBar.add(Box.createHorizontalGlue());The menu added after the usage of above method, would get right-aligned −JMenu sourceMenu = new JMenu("Source"); sourceMenu.setMnemonic(KeyEvent.VK_S); menuBar.add(sourceMenu);The following is an example to right-align a menu in the menu bar with Java −Examplepackage my; import java.awt.event.KeyEvent; import javax.swing.Box; 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[]) {       ...
