The multiplexing look and feel allows users to combine auxiliary look and feels with the default look and feel. For example, a user could use an auxiliary audio look and feel in combination with the Motif look and feel. When a component instance asks for its UI, the Multiplexing Look and Feel returns a Multiplexing UI that handles all communications with both the auxiliary and the default look and feels. For example, JButton.getUI may get an instance of MultiButtonUI, which would handle both a MotifButtonUI and an AudioButtonUI. @since JDK1.2
