Answer 1

你说的应该是界面风格吧LookAndFeel？main()方法的最前面写，整个程序可以应用。
        try {
            //UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsClassicLookAndFeel");//Windows风格
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");//Windows系统风格
            //UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");//Java风格
            //UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel");//Unix风格
         } catch (ClassNotFoundException ex) {
            
        } catch (InstantiationException ex) {        } catch (IllegalAccessException ex) {        } catch (UnsupportedLookAndFeelException ex) {        }
