Java Program to center a JLabel in a JPanel with LayoutManager

Java 8Object Oriented ProgrammingProgramming

Here, we are using the LayoutManager GridBagLayout to center the components. We have two components here including a label and we have set the layout as GridBagLayout −

JLabel label = new JLabel("Name (Centered Label): ");
JTextArea text = new JTextArea();
text.setText("Add name here...");
panel.setLayout(new GridBagLayout());

The following is an example to center a JLabel in a JPanel with LayoutManager −

Example

package my;
import java.awt.GridBagLayout;
import javax.swing.BorderFactory;
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("Demo Frame");
      JPanel panel = new JPanel();
      JLabel label = new JLabel("Name (Centered Label): ");
      JTextArea text = new JTextArea();
      text.setText("Add name here...");
      panel.setLayout(new GridBagLayout());
      panel.add(label);
      panel.add(text);
      panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
      frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
      frame.add(panel);
      frame.setSize(500, 300);
      frame.setVisible(true);
   }
}
