示例1: start

/**
* Plays the clip with the specified volume.
* @param volume the volume the play at
* @param listener the line listener
* @throws LineUnavailableException if a clip object is not available or
* if the line cannot be opened due to resource restrictions

示例2: PreloadedPlayback
import javax.sound.sampled.Clip; //导入方法依赖的package包/类
/**
* Creates a new {@code PreloadedPlayback}. PreloadedPlayback objects will
* always be created by their associated PreloadedAudio object.
* <p>
* IMPLEMENTATION NOTE: Originally, the fetching of a new {@code Line} was
* done in the {@code run} method, however testing revealed that latency is
* decreased if a {@code Line} is acquired ahead of time, here in the
* constructor.
*
* @param audio
* The {@code Audio} that created this {@code PreloadedPlayback}.
* @param audioFormat
* Specifies the particular arrangement of audio data.
* @param audioBytes
* Holds the audio data from which a {@code Clip} will be
* created.
* @param instanceID
* The {@code instanceID} of this {@code PreloadedPlayback}.
