我想创建 2JMenuItem
可以启动和停止背景音频。
这是我的代码:
public class MainClass extends JFrame
{
private AudioInputStream audioInputStream;
private Clip clip;
public MainClass(String title)
{
try
{
audioInputStream = AudioSystem.getAudioInputStream(new File("Background.wav"));
clip = AudioSystem.getClip();
clip.loop(Clip.LOOP_CONTINUOUSLY);
clip.open(audioInputStream);
}
catch(Exception e)
{
System.out.println("Error with playing sound.");
e.printStackTrace();
}
}
public void startSound()
{
clip3.start();
settingSubMenuItem1.setEnabled(false);
settingSubMenuItem2.setEnabled(true);
}
public void stopSound()
{
clip3.stop();
settingSubMenuItem1.setEnabled(true);
settingSubMenuItem2.setEnabled(false);
}
private class MenuItemListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
if(e.getSource() == settingSubMenuItem1)
{
startSound();
}
if(e.getSource() == settingSubMenuItem2)
{
stopSound();
}
}
}
}
当我单击 时settingSubMenuItem1
,它工作正常,播放音频。
但是当我点击 时settingSubMenuItem2
,出现错误,如果再次点击settingSubMenuItem1
,就没有声音了。
这是错误:
Error with playing sound.
java.lang.IllegalStateException: Clip is already open with format PCM_SIGNED 44100.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian and frame lengh of 7658
我的程序有什么错误?
