सिस्टम एल एंड एफ का उपयोग करना

स्विंग काफी कुछ देशी एल एंड एफएस का समर्थन करता है।
आप हमेशा एक विशिष्ट एल एंड एफ वर्ग के लिए कॉल किए बिना आसानी से स्थापित कर सकते हैं:

public class SystemLookAndFeel
{
    public static void main ( final String[] args )
    {
        // L&F installation should be performed within EDT (Event Dispatch Thread)
        // This is important to avoid any UI issues, exceptions or even deadlocks
        SwingUtilities.invokeLater ( new Runnable ()
        {
            @Override
            public void run ()
            {
                // Process of L&F installation might throw multiple exceptions
                // It is always up to you whether to handle or ignore them
                // In most common cases you would never encounter any of those
                try
                {
                    // Installing native L&F as a current application L&F
                    // We do not know what exactly L&F class is, it is provided by the UIManager
                    UIManager.setLookAndFeel ( UIManager.getSystemLookAndFeelClassName () );
                }
                catch ( final ClassNotFoundException e )
                {
                    // L&F class was not found
                    e.printStackTrace ();
                }
                catch ( final InstantiationException e )
                {
                    // Exception while instantiating L&F class
                    e.printStackTrace ();
                }
                catch ( final IllegalAccessException e )
                {
                    // Class or initializer isn't accessible
                    e.printStackTrace ();
                }
                catch ( final UnsupportedLookAndFeelException e )
                {
                    // L&F is not supported on the current system
                    e.printStackTrace ();
                }

                // Now we can create some natively-looking UI
                // This is just a small sample frame with a single button on it
                final JFrame frame = new JFrame ();
                final JPanel content = new JPanel ( new FlowLayout () );
                content.setBorder ( BorderFactory.createEmptyBorder ( 50, 50, 50, 50 ) );
                content.add ( new JButton ( "Native-looking button" ) );
                frame.setContentPane ( content );
                frame.setDefaultCloseOperation ( WindowConstants.EXIT_ON_CLOSE );
                frame.pack ();
                frame.setLocationRelativeTo ( null );
                frame.setVisible ( true );
            }
        } );
    }
}

कस्टम एल एंड एफ का उपयोग करना

                // Now we can create some pretty-looking UI

                final JFrame frame = new JFrame ();

ध्यान रखें कि इस बिंदु पर कुछ L & Fs काफी पुराने हो सकते हैं।
