Java – change the default jlabel font

How do I set the default font for all jlabel instances Instead of setting the font for each jlabel separately

Solution

Use uimanager to define the default font of jlabel:

import java.awt.FlowLayout;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.UIManager;

public class LabelFont {

   public static void main(String[] args) {
      Font oldLabelFont = UIManager.getFont("Label.font");
      UIManager.put("Label.font",oldLabelFont.deriveFont(Font.PLAIN));

      JFrame f = new JFrame("LabelFont Test");
      f.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
      f.getContentPane().setLayout(new FlowLayout());

      JLabel df = new JLabel("Default JLabel font");
      f.getContentPane().add(df);

      JLabel ef = new JLabel("Font explicitly set");
      ef.setFont(oldLabelFont);
      f.getContentPane().add(ef);

      f.pack();
      f.setVisible(true);
   }
}
