Change JLabel Font in Java

To change JLabel font, use the setFont() method −

JLabel lable = label.setFont(new Font("Verdana", Font.PLAIN, 18));

Example

package my;
import java.awt.Font;
import javax.swing.*;
public class SwingDemo {
   public static void main(String args[]) {
      JFrame frame = new JFrame("Label Example");
      JLabel label;
      label = new JLabel("First Label");
      label.setBounds(50, 50, 100, 30);
      label.setFont(new Font("Verdana", Font.PLAIN, 18));
      frame.add(label);
      frame.setSize(300,300);
      frame.setLayout(null);
      frame.setVisible(true);
   }
}
