更改默认的JLabel字体

使用

UIManager

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);   }}
