How to center a JLabel in a JPanel with GridBagLayout in Java?
Center a component in a JPanel with GridBagLayout. Let us first create a JFrame and JPanel inside it -
JFrame frame = new JFrame("Demo Frame");
JPanel panel = new JPanel();Now, we will add our components −
JLabel label = new JLabel("Demo Label (Centered)");
label.setForeground(Color.white);
JCheckBox checkBox = new JCheckBox("Checkbox (Centered)");Set the layout −
panel.setLayout(new GridBagLayout());
The following is an example to center a label in a panel with GridBagLayout −

package my;
import java.awt.Color;
import java.awt.GridBagLayout;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.WindowConstants;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame("Demo Frame");
JPanel panel = new JPanel();
JLabel label = new JLabel("Demo Label (Centered)");
label.setForeground(Color.white);
JCheckBox checkBox = new JCheckBox("Checkbox (Centered)");
panel.setLayout(new GridBagLayout());
panel.add(label);
panel.add(checkBox);
