Examples of VolumeControl

javax.microedition.media.control.VolumeControl
VolumeControl is an interface for manipulating the audio volume of a Player.
Volume Settings
This interface allows the output volume to be specified using an integer value that varies between 0 and 100.
Specifying Volume in the Level Scale
The level scale specifies volume in a linear scale. It ranges from 0 to 100, where 0 represents silence and 100 represents the highest volume. The mapping for producing a linear multiplicative value is implementation dependent.

Mute
Setting mute on or off doesn't change the volume level returned by getLevel. If mute is true, no audio signal is produced by this Player; if mute is false an audio signal is produced and the volume is restored.
Volume Change Events
When the state of the VolumeControl changes, a VOLUME_CHANGED event is delivered through the PlayerListener. @see javax.microedition.media.Control @see javax.microedition.media.Player @see javax.microedition.media.PlayerListener
