The Methods Defined by the AppletContext Inter face
The AudioClip Interface
The AudioClip interface defines these methods: play( ) (play a clip from the beginning),
stop( ) (stop playing the clip), and loop( ) (play the loop continuously). After you have
loaded an audio clip using getAudioClip( ), you can use these methods to play it.
The AppletStub Interface
The AppletStub interface provides the means by which an applet and the browser (or applet
viewer) communicate. Your code will not typically implement this interface.
