Specifying the look and feel:

The look and feel can be specified in two distinct ways: by specifying the fully qualified name of the class for the look and feel, or by creating an instance of LookAndFeel and passing it to setLookAndFeel. The following example illustrates setting the look and feel to the system look and feel.   

  UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
   

The following example illustrates setting the look and feel based on class name:

  UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
