每次按下mi app中的“播放”按钮都会引发以下错误：

任何人都知道为什么？
我不知道为什么抛出错误我不知道如何解决它。 我使用带有JDK 1.7和vlcj库的NetBeans IDE来播放音频和视频以及jna库。
这是mi app的代码

感谢您的帮助！
答案 0 :(得分：3)
很简单;看看你的 actionPerformed（）方法。它说：
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated
令人惊讶的是，这会引发异常。无条件地，作为处理其他“动作”代码的最后一步。总是
该声明可能是由您的IDE创建的。只需删除该行！
许多IDE的默认行为是为您生成新代码;但他们必须投入一些东西。并且您的IDE（或者开始编写该代码的人将该异常放入该方法体中以指示：“here work todo”）。然后你只是忘了删除那个抛出语句！
提示：如果你真的不知道那条线在做什么;然后我建议退一步进行UI编程。然后你最好在下周学习这种绝对的java基础知识。否则，您将从一个问题运行到下一个问题。当你几乎无法爬行时，不要试图跑！
答案 1 :(得分：0)
public void actionPerformed(ActionEvent e) {
String archivo = "";
if(e.getSource() == check1){
lista = abrirArchivo();
archivo = dato.getRuta();
label1.setText(archivo);
} else if (e.getSource() == check2){
archivo = abrirVideo();
label2.setText(archivo);
}else if (e.getSource() == check3){
try {
archivo = abrirAudio();
} catch (IOException ex) {
Logger.getLogger(AppJelic.class.getName()).log(Level.SEVERE, null, ex);
}
label3.setText(archivo);
}else if (e.getSource().equals(boton)){
flag=true;
if(ourMediaPlayer != null){
ourMediaPlayer.getMediaPlayer().stop();
}
if(ourPlayer != null){
ourPlayer.getMediaPlayer().stop();
}
audioVideo();
}
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
无论结果如何，您方法的最后一个语句都会抛出此异常。删除该行，看看是否能解决问题！
