How to create a Box Layout in Java?

To create a Box Layout in Java Swing, use the BoxLayout class. Here, we have also set that the components should be laid our left to right or top to bottom −

Box box = new Box(BoxLayout.X_AXIS); box.add(button1); box.add(button2); box.add(button3); box.add(button4); box.add(Box.createGlue()); box.add(button5); box.add(button6); box.add(button7); box.add(button8);

Above, we have 8 buttons in our Box Layout. We have separated 4 buttons each using the createGlue() method.

The following is an example to create a BoxLayout in Java −

Example

package my; import java.awt.BorderLayout; import javax.swing.Box; import javax.swing.BoxLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JScrollPane; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Groups");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JButton button1 = new JButton("CSK");       JButton button2 = new JButton("DC");       JButton button3 = new JButton("MI");       JButton button4 = new JButton("SRH");       JButton button5 = new JButton("RR");       JButton button6 = new JButton("KKR");       JButton button7 = new JButton("KXIP");       JButton button8 = new JButton("RCB");       Box box = new Box(BoxLayout.X_AXIS);       box.add(button1);       box.add(button2);       box.add(button3);       box.add(button4);       box.add(Box.createGlue());       box.add(button5);       box.add(button6);       box.add(button7);       box.add(button8);       JScrollPane jScrollPane = new JScrollPane();       jScrollPane.setViewportView(box);       frame.add(jScrollPane, BorderLayout.CENTER);       frame.setSize(550, 250);       frame.setVisible(true);    } }
