How to create Glue to fill the space between neighbouring components in Java?

Let’s say we have 6 components and we need to fill the space between some of them −

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");

To fill the space and separate components, create a Glue using the createGlue() method −

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

The following is an example to fill the space between neighbouring components −

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("Matches");
      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");
      Box box = new Box(BoxLayout.X_AXIS);
      box.add(button1);
      box.add(button2);
      box.add(Box.createGlue());
      box.add(button3);
      box.add(button4);
      box.add(Box.createGlue());
      box.add(button5);
      box.add(button6);
      JScrollPane jScrollPane = new JScrollPane();
      jScrollPane.setViewportView(box);
      frame.add(jScrollPane, BorderLayout.CENTER);
      frame.setSize(550, 250);
      frame.setVisible(true);
   }
}
