我有两种声音，我想在按下按钮后播放第一首歌，在声音结束后，我想播放第二种声音。因此，如果第一个声音结束播放第二个声音，我想使用if语句。

this.setLocation(790, 0);
this.add(button);
this.add(button2);
this.add(label);
this.getContentPane().setBackground(Color.BLACK);
this.setLayout(null);
}这是按钮功能，我想如果我按下按钮，剪辑2开始，结束后，第一个剪辑开始
public void actionPerformed(ActionEvent e) {
if (e.getSource() == button) {
JOptionPane.showMessageDialog(null, "niiiiiiiiiice");
clip2.start();
getContentPane().removeAll();
repaint();
label.setText("What is 1+1");
this.add(button3);
this.add(button4);
this.add(label);
}
if(e.getSource()==button2){
System.exit(0);
}
}
}

Clip工具Line，因此可以使用linelistener在Clip结束（lineevent.type=stop）。可以将实现侦听的类设置为在接收到通知时触发您希望发生的下一件事情。
